Peter does not offer two mutually exclusive medical diagnoses, as though the deficient believer were at once unable to see and able to see only nearby. The predicate adjective τυφλός (typhlos, “blind”) gives the principal judgment, while μυωπάζων (myōpazōn), a present active participle agreeing with the implied masculine subject, further depicts the manner of that blindness: he is blind because his sight has become constricted, squinting and unable to see beyond what lies immediately before him. The rare verb is related to the idea of closing or contracting the eyes and appropriately bears the sense “being short-sighted” or “squinting.” The phrase is therefore climactic and pictorial rather than clinically precise. In context, the failure of sight concerns “these things,” namely the qualities enumerated in vv. 5–7. The person who does not possess and cultivate faith’s moral fruit has lost spiritual perspective. He cannot perceive the relation between present sanctification, God’s effective call and election (v. 10), and the promised entrance into Christ’s eternal kingdom (v. 11). The final participial clause, λήθην λαβών (lēthēn labōn, “having taken/received forgetfulness”), explains this impaired vision: he has allowed forgetfulness to overtake him concerning “the cleansing of his old sins.” The contrast is not between intellectual ignorance and saving knowledge, but between a confession of cleansing and a morally forgetful condition that fails to reckon with the cleansing already received. Peter’s imagery thus rebukes a spiritually myopic profession whose lack of the virtues exposes a serious failure to apprehend the grace and future hope that ought to govern Christian conduct.

Peter intentionally distinguishes φιλαδελφία (philadelphia, “brotherly affection”) from ἀγάπη (agapē, “love”), although the semantic fields of the two terms overlap. Philadelphia denotes the affection proper to those bound together as siblings, and in early Christian usage it particularly characterizes the mutual attachment of believers as members of God’s household. Agapē, placed as the final quality in the sequence, denotes the fuller and governing love that gives itself for the good of another. The progression is therefore not from an inferior natural affection to a wholly unrelated virtue, but from love for the brethren to love in its comprehensive Christian form. The syntax continues the pattern established in vv. 5–6: “in [or with] godliness, brotherly love; and in brotherly love, love.” The accusatives τὴν φιλαδελφίαν and τὴν ἀγάπην depend on the supplying imperative of v. 5, ἐπιχορηγήσατε (epichorēgēsate, aorist active imperative, “supply” or “furnish”). Each virtue is to be furnished in connection with the preceding one; godliness must issue in concrete familial affection within the covenant community, and such affection must mature into agapē. The repeated articles identify recognizable moral qualities rather than vague sentiments. Peter’s wording in 1 Peter 1:22 provides a close parallel: believers have purified their souls “for sincere brotherly love” (philadelphian), and therefore are commanded to “love” (agapēsate, aorist active imperative) one another earnestly. There too brotherly affection is not abolished by agapē but carried into its earnest, holy expression. In 2 Peter 1:7 the unqualified final ἀγάπη most naturally has a breadth not restricted to the church, while necessarily including the brethren. It is the climactic virtue because it reflects the moral character of the God who has called his people and gives proper form to every preceding quality.

Peter most likely invokes the Jewish interpretation that connected the angelic rebellion with the events preceding the flood in Genesis 6, but he does not himself provide an exposition of the “sons of God” in that passage. The sequence of examples—sinning angels, the ancient world and Noah, and Sodom and Gomorrah (vv. 4–6)—closely resembles Jude 6–7, where the angels are said to have abandoned their proper dwelling. The juxtaposition of the angels with Noah therefore makes an allusion to the Genesis 6 tradition highly probable, particularly the tradition in which heavenly beings transgressed divinely fixed boundaries before the flood. Yet 2 Peter 2:4 identifies these beings only as “angels who sinned” (angelōn hamartēsantōn), with the genitive aorist participle describing the persons whom God did not spare. The verse concentrates not on the precise character of their sin but on God's judicial action: having cast them into Tartarus (tartarōsas), he “handed [them] over” (paredōken) in dark chains, being kept (tēroumenous, present passive participle) for the final judgment. Genesis 6 itself neither explicitly calls the “sons of God” angels nor describes their imprisonment. Consequently, Peter's language should not be used to settle every disputed question concerning Genesis 6. It does show, however, that Peter regards a real angelic rebellion and present divine confinement of its perpetrators as a fitting first example of the certainty of God's judgment upon the ungodly.

The reciprocal formulation denies that the apparent length of the delay before the day of the Lord measures either God’s faithfulness or his ability to fulfill his promise. The first comparison, “one day with the Lord is as a thousand years,” answers the scoffers’ premise that the passing of many years constitutes evidence against the promise (3:3–4). The reversed comparison, “a thousand years as one day,” excludes the opposite inference: a long historical period does not make the promised day remote or difficult for the Lord to bring about. In both directions, creaturely calculations of delay cannot govern judgment concerning the divine promise. The language deliberately recalls Psalm 90:4, where a thousand years in God’s sight are like a day that has passed. Peter’s wording is not a bare quotation, however, but an adapted and intensified allusion suited to his argument. The phrase παρὰ κυρίῳ (para kyriō, “with/before the Lord”) locates the comparison in relation to the Lord’s perspective and sovereign action, not in an abstract speculation about time. The present imperative μὴ λανθανέτω (mē lanthanetō, “let this not escape [notice]”) marks the assertion as the decisive fact the beloved must retain amid the scoffers’ objection. The verse therefore teaches God’s transcendence over temporal limitations and his freedom in ordering redemptive history; it does not provide a conversion formula by which prophetic “days” must equal literal thousand-year periods. Its immediate sequel makes the point explicit: what appears to be slowness is divine patience, while the day of the Lord remains certain (3:9–10).

Peter presents grace and peace as divine blessings that are to increase through the believers’ knowledge of God and Jesus Christ. The verb πληθυνθείη (plēthyntheiē), an aorist passive optative, expresses a benedictory wish: “may [grace and peace] be multiplied.” The singular verb governs the closely joined nouns χάρις (charis) and εἰρήνη (eirēnē), which together form a unified summary of God’s saving favor and the wholeness and reconciliation that attend it. The passive voice leaves the giver unstated, but the context makes God the effective agent; grace and peace are not self-generated spiritual attainments but gifts God causes to abound. The phrase ἐν ἐπιγνώσει (en epignōsei), “in/by the knowledge,” denotes more than the intellectual environment in which grace and peace are recognized. In this context it identifies the sphere and instrumental means of their multiplication: God’s benefits abound as his people come truly to know him and Jesus Christ. Ἐπίγνωσις (epignōsis) commonly conveys full or genuine knowledge, and throughout the letter it stands opposed to the moral and doctrinal blindness of the false teachers. It is therefore not secret or speculative knowledge, but the covenantal knowledge of the God revealed in Christ, a knowledge inseparable from faith, obedience, and participation in the divine promises (1:3–4, 8). The genitives “of God and of Jesus our Lord” identify the object of this knowledge. They distinguish God and Jesus personally while placing Jesus, designated “our Lord,” within the single saving knowledge by which divine grace and peace are communicated.

Peter’s expression is more concrete than the English rendering “eyes full of adultery” immediately suggests. Μοιχαλίδος is the genitive singular of μοιχαλίς (moichalis), ordinarily a substantival feminine term meaning “adulteress,” and it depends on μεστούς (mestous, “full”), which commonly takes a genitive of that with which something is filled. Literally, then, the teachers have “eyes full of an adulteress.” The phrase portrays a gaze dominated by the prospect or image of illicit sexual intercourse: they look upon women not with purity but as objects of adulterous desire. “Full of adultery” is therefore an interpretive translation that accurately conveys the moral force, though it softens Peter’s deliberately personal and visual wording. The singular need not identify one particular woman or establish that the teachers sought only married women already engaged in adultery. Greek can use a singular substantive generically, and the expression likely represents the adulteress as the embodiment of the sexual object of their desire. The following phrase, “not ceasing from sin,” confirms that this is not a passing temptation but a settled, continuous moral disposition; ἀκαταπαύστους (akatapaustous) agrees with “eyes” and depicts eyes that are incapable of resting from sin. In the immediate context, these men indulge their passions openly (2:10, 13), and their predatory character is made explicit by the present participle δελεάζοντες (deleazontes, “enticing”): their uncontrolled sexual vision belongs to their wider program of ensnaring “unestablished souls,” not merely to private inward lust.

The masculine dative plural relative pronoun οἷς (hois, “for whom”) makes clear that the “gloom of darkness” is reserved not for the metaphorical springs and mists but for the male false teachers introduced by Οὗτοί (“these men”). The two predicate images, πηγαὶ ἄνυδροι (“waterless springs”) and ὁμίχλαι (“mists”), are grammatically feminine because their nouns are feminine, as is the participle ἐλαυνόμεναι (present passive participle, nominative feminine plural, “being driven”). Yet Peter resumes the personal referent with the masculine pronoun. The imagery describes the teachers; the judgment belongs to the persons so described. This grammatical shift also sharpens the force of the metaphors. Like springs that promise water but yield none, these teachers advertise refreshment while providing no life-giving truth. Like mists violently driven by a storm (ὑπὸ λαίλαπος), they possess neither stability nor direction. Their apparent spiritual promise is therefore exposed as empty and transient. The closing clause reverses their pretensions: those who offer deceptive illumination are assigned ὁ ζόφος τοῦ σκότους, literally “the gloom of darkness,” an intensified expression for the realm of divine judgment. The perfect passive τετήρηται (from tēreō, “has been kept/reserved”) presents this punishment as already fixed and guarded for them. The passive naturally implies God as the one who has reserved it, in keeping with the preceding assertion that the Lord knows how to keep the unrighteous under punishment for the day of judgment (2:9). Jude 13 employs closely parallel language and explicitly adds “forever”; although that temporal phrase is not present in the usual text of 2 Peter 2:17, the immediate context and the established judicial reservation indicate final eschatological condemnation rather than a merely temporal consequence.

Peter grounds the commanded pursuit of virtue and knowledge in God’s prior gift, rather than setting human moral effort alongside grace as an independent source. “For this very reason” (kai auto touto de) points back to the divine power that has granted all things necessary for life and godliness (v. 3) and to the precious promises through which believers become partakers of the divine nature and escape corruption (v. 4). The aorist participle pareisenenkantes, “having brought in” or “bringing alongside,” is subordinate to the aorist imperative epichorēgēsate, “supply.” The participle identifies the manner accompanying the command: all diligence (spoudēn pasan) is to be brought to bear in furnishing the qualities that follow. The imperative does not imply a merely momentary act, but summons a decisive, wholehearted undertaking. The verb epichorēgeō originally could denote the generous provision made by a sponsor for a chorus, and in Hellenistic usage it came to mean to furnish abundantly. Peter therefore does not envision a minimal addition to faith, but the full cultivation of a coherent moral life. Yet this earnest supplying is not self-generated moral achievement. The sequence begins with “your faith,” the faith already received through the righteousness of Jesus Christ (v. 1), and it follows the declaration that God has already granted what is needed (v. 3). Divine provision establishes both the possibility and the obligation of diligent growth. Peter thus excludes both passivity, since believers must supply these graces with every diligence, and autonomous self-reliance, since the whole exhortation rests on God’s effective calling and promises. The repeated preposition en, “in,” presents the ensuing traits as developing in connection with one another: virtue is to be supplied in faith, and knowledge in virtue. Virtue (aretē) here denotes moral excellence, an especially fitting term because God’s own excellence is named in v. 3. Knowledge (gnōsis) is not the secret or speculative knowledge claimed by false teachers, but the discernment that belongs to a life of moral excellence and accords with the knowledge of Christ emphasized throughout the chapter. Faith, therefore, is neither displaced by ethical qualities nor left barren; it is the foundational reality in which virtue and knowledgeable obedience are to be richly furnished.

Peter is not presenting water as an independently existing, eternal substance alongside God; he is summarizing the Genesis creation narrative in order to expose the scoffers’ selective forgetting of God’s past interventions in the world. The feminine perfect participle συνεστῶσα (synestōsa, from synistēmi), agreeing with γῆ (gē, “earth”), denotes an earth that had been constituted or established and remained so. Its perfect tense suitably portrays the ordered earth as the enduring result of God’s creative act. The final dative phrase, τῷ τοῦ θεοῦ λόγῳ (“by the word of God”), identifies the effective cause of that constitution: creation is governed by God’s commanding word, not by an autonomous natural process. The paired phrases ἐξ ὕδατος (“out of water”) and δι’ ὕδατος (“through water”) recall Genesis 1:2, 6–10. The waters are present in the initial, unformed condition, are divided by the expanse, and are gathered so that dry land appears. “Out of water” most directly refers to the earth’s emergence from the gathered waters; “through water” emphasizes water’s role in the process by which the habitable world was ordered. Peter’s wording is compressed rather than technical cosmology, but it intentionally makes water prominent because the same element becomes the means of the world’s destruction in the following verse (3:6). Accordingly, the verse does not itself argue the doctrine of creation ex nihilo by philosophical formulation, yet neither does it deny it. Peter assumes the Old Testament’s fundamental confession that God alone made heaven and earth and that his word is determinative. His immediate point is historical and polemical: the created order, which the scoffers treat as permanently uniform, was established by God’s word amid and by means of waters, and that same world was later judged through water. The creation account thus supplies the first premise for Peter’s rebuttal of their denial of a future divine judgment.

The “any” and “all” are most naturally read in relation to the addressees, the beloved whom Peter has addressed throughout this section (3:1, 8, 14, 17). The prepositional phrase εἰς ὑμᾶς (“toward you”) supplies the immediate sphere of the Lord’s μακροθυμία (makrothymia, “patience”): the apparent delay of the parousia serves the saving end of bringing all those toward whom this patience is exercised to repentance. Thus τινας (“any”) and πάντας (“all”), both masculine plural substantives, are not abstract statements detached from the discourse but are explained by the preceding “you.” Grammatically, μὴ βουλόμενος (“not willing,” a present middle participle agreeing with κύριος, “the Lord”) governs the two aorist infinitives ἀπολέσθαι (“to perish”) and χωρῆσαι (“to come” or “to make room for oneself”) εἰς μετάνοιαν (“unto repentance”). Peter contrasts perishing with entering repentance, not a merely temporary postponement with a change in the divine timetable. The same purpose appears in v. 15, where the Lord’s patience is to be reckoned as salvation. The delay is therefore neither divine negligence nor an uncertain experiment; it is the means by which the promised salvation reaches its appointed consummation before the day of judgment arrives. The verse consequently should not be made to teach universal salvation, since the surrounding context repeatedly affirms the destruction of the ungodly (3:7) and the certainty of judgment. Nor does its language, considered in isolation, settle every question concerning the extent of the atonement. It does, however, declare the Lord’s efficacious saving purpose toward his people: none of those embraced by his patient purpose will finally perish, but all will come to repentance. This contextual restriction accords with the Reformed distinction between God’s saving decree, which unfailingly accomplishes salvation for his elect, and the universal summons to repentance announced elsewhere in Scripture. Here Peter’s concern is specifically to assure the threatened and mocked church that the delay of Christ’s return is governed by mercy and will not leave the Lord’s own people unfinished.

Peter explicitly characterizes Noah as a κῆρυξ δικαιοσύνης (kēryx dikaiosynēs), “a herald of righteousness,” and thus presents him as more than a private survivor whose obedience was known only within his household. The noun κῆρυξ denotes a public herald or announcer, ordinarily one commissioned to proclaim a message. The genitive δικαιοσύνης is most naturally objective or descriptive: Noah proclaimed righteousness—God’s righteous standard and, in the immediate setting of judgment, the righteousness that distinguishes the godly from the ἀσεβεῖς (asebeis), the ungodly. Peter therefore understands Noah’s life amid the corrupt antediluvian world as including a witness that exposed its guilt. Genesis does not preserve the content or occasions of Noah’s proclamation, and this statement should not be expanded into a detailed account of prolonged evangelistic preaching beyond the evidence supplied. Nevertheless, Peter’s designation is not reducible merely to Noah’s righteous conduct. Noah’s obedient construction of the ark certainly functioned as a visible testimony; Hebrews 11:7 similarly says that by faith he “condemned the world.” Yet κῆρυξ normally denotes one who announces, and Peter’s wording supports the conclusion that Noah bore verbal witness as well as exemplary witness to God’s righteousness and coming judgment. The title also serves Peter’s argument in 2:4–10. God did not spare the ancient κόσμος (kosmos), but he “guarded” Noah (ἐφύλαξεν, aorist active of phylassō) while bringing the flood upon a world marked by ungodliness. Noah’s heralding of righteousness consequently sharpens the justice of the flood: the judgment fell not upon an uninformed or morally neutral world, but upon those set over against the righteous testimony embodied and proclaimed by Noah. At the same time, the preservation of Noah and his household confirms the larger assertion that the Lord distinguishes the righteous from the ungodly in judgment.

The expression εἰς ἡμέραν αἰῶνος, literally “unto a day of eternity,” is not merely a decorative equivalent of “forever.” It denotes the eschatological horizon in which Christ’s glory is openly and irrevocably displayed. The accusative ἡμέραν is governed by εἰς, while αἰῶνος functions as a genitive characterizing the day: it is the day belonging to, or marked by, the eternal age. English versions therefore rightly render the sense as “forever,” “forever and ever,” or “to the day of eternity,” though the latter preserves Peter’s distinctive temporal and eschatological imagery. The wording gathers up the chapter’s repeated concern with the coming “day of the Lord” (3:10) and “day of God” (3:12), when the present order is judged and the promised new heavens and new earth are realized (3:13). Peter does not identify the phrase mechanically with one isolated twenty-four-hour event; rather, the final day is viewed as the threshold and abiding manifestation of the age without end. The glory ascribed to Jesus Christ belongs to him already—“now”—and will continue into that consummated eternal day. The temporal pair καὶ νῦν καὶ εἰς ἡμέραν αἰῶνος therefore joins Christ’s present exaltation with his everlasting eschatological glory. The antecedent of αὐτῷ (“to him”) is Jesus Christ, the immediately preceding “our Lord and Savior.” The single article τοῦ governing both κυρίου and σωτῆρος, with the two singular personal nouns joined by καί, identifies one person: “our Lord and Savior, Jesus Christ.” Thus the doxology is directed to Christ himself, fitting the letter’s climactic confession that the one who saves and rules the church receives glory now and in the eternal consummation.

The reading ἐν ταῖς ἀπάταις αὐτῶν (en tais apatais autōn), “in their deceptions,” is to be preferred over the variant “in their love feasts.” Peter does not identify the meal itself as an ἀγάπη (agapē), a Christian fellowship feast, although συνευωχούμενοι ὑμῖν (syneuōchoumenoi hymin), “feasting together with you,” plainly indicates that these teachers participated in the community’s common meals. Rather, the present participle ἐντρυφῶντες (entryphōntes), “reveling,” locates their self-indulgence within the sphere of “their deceptions”: their corrupt teaching and deceitful conduct accompanied, and likely exploited, their continued outward fellowship with the churches. The variant ἐν ταῖς ἀγάπαις αὐτῶν, “in their love feasts,” is readily explained as assimilation to Jude 12, which describes intruders “feasting together” at the believers’ love feasts. The verbal resemblance between Jude and 2 Peter—especially the participle συνευωχούμενοι—would naturally prompt a copyist to replace the less familiar ἀπάταις (apatais, “deceptions”) with ἀγάπαις (agapais, “love feasts”). The more difficult reading, supported by the stronger textual evidence, also suits Peter’s sustained portrayal of the teachers as agents of fraud (2 Pet. 2:1–3, 18–19). Jude’s wording may preserve a more explicit designation of the communal setting; Peter’s wording emphasizes the moral contradiction that such deceivers could share the believers’ table while indulging the very lies and sensuality that marked them as “spots and blemishes.”

The participle σπεύδοντας (speudontas, present active participle, accusative masculine plural) means more than merely moving eagerly toward the day; joined with the accusative object τὴν παρουσίαν, “the coming,” it ordinarily conveys hastening its arrival. Peter therefore presents the holy conduct and godliness of v. 11 as connected, in God’s appointed order, with the approach of the final day. The faithful are not passive spectators of the promised consummation, but await it in a manner that accords with and serves God’s redemptive purpose. This language does not imply that human conduct controls a date unknown to God or alters an otherwise uncertain divine decree. The same context grounds the apparent delay in the Lord’s patience and his purpose that people should come to repentance (3:9), while the day remains certain because it rests upon God’s word (3:5–7, 10). Peter can thus speak both of God’s settled judgment and of believers’ participation in the means by which his purpose advances. Their godly life belongs to the divinely ordained history leading toward the day; it does not place the day at human disposal. Some render σπεύδω here as “eagerly desiring” or “hurrying toward,” thereby avoiding the notion that believers hasten the event itself. Such a sense is possible in some contexts, but the direct object “the coming of the day of God” favors the stronger rendering, “hastening the coming.” The paired participles προσδοκῶντας (prosdokōntas, “expecting”) and σπεύδοντας distinguish watchful expectation from an active orientation toward the consummation. Peter’s point is that eschatological hope expresses itself in conduct consonant with the approaching renewal, even as the day’s arrival remains wholly God’s act.

The reading “will be exposed” is a defensible rendering of the difficult Greek verb εὑρεθήσεται (heuriskō, future passive indicative, third singular), literally, “will be found.” In this setting, however, “found” carries a forensic sense: the earth and everything done upon it will be laid bare before the Judge and shown for what it is. The verse therefore does not merely describe cosmic combustion; it depicts the disclosure of the created order and of human works on the day of the Lord. This accords with the immediate context, in which the present world is reserved for fire “for the day of judgment and destruction of ungodly men” (3:7), and with Peter’s later use of the same verb for believers being “found” by Christ in peace, spotless and blameless (3:14). The textual question is significant because many later Greek manuscripts read κατακαήσεται, “will be burned up,” a reading reflected in several older English versions. Other witnesses offer still different attempts to resolve the difficulty, including “will not be found” and “will disappear.” Yet εὑρεθήσεται has strong early textual support and is more likely to have generated the smoother alternatives than to have arisen from them. Scribes encountering the apparently abrupt statement that the earth and its works “will be found” could readily substitute a verb more obviously suited to the preceding fire imagery. The harder reading consequently best explains the rise of the variants. The singular εὑρεθήσεται most naturally treats γῆ, “earth,” as the leading subject, while τὰ ἐν αὐτῇ ἔργα, “the works in it,” is joined to it as the contents that share its exposure. The preceding clauses affirm the passing away of the heavens and the dissolution of the στοιχεῖα (stoicheia), the constituent elements of the present cosmic order, while this final clause emphasizes the judicial result. The text need not deny the fiery destruction already stated; rather, the fire serves the comprehensive unveiling in which neither the world nor its deeds can remain concealed.

Peter distinguishes the inward mastery of desires from the steadfast constancy required when faith is tested. ἐγκράτεια (enkrateia), "self-control," denotes mastery over one’s appetites and impulses; it is the moral restraint by which knowledge is not merely possessed but governed in conduct. ὑπομονή (hypomonē), "endurance" or "perseverance," denotes the capacity to remain steadfast under pressure, distress, or delay. The latter is not simply a stronger form of the former: self-control restrains the disordered response within, whereas endurance bears up faithfully against adversity without. The syntax presents these qualities as elements to be supplied in a progressive, interrelated sequence. Each preceding virtue stands in the dative after ἐν (en), while the following virtue is accusative, dependent on the governing imperative ἐπιχορηγήσατε (epichorēgēsate, "supply" or "furnish") in v. 5: "in self-control, endurance." The preposition need not mean that endurance is mechanically produced by self-control, but it marks the sphere or context in which the next quality is to be furnished. Nevertheless, the order is morally intelligible. A person unable to govern passions, fears, and immediate reactions will not readily remain firm when suffering, opposition, or the apparent postponement of God’s promises comes. Thus disciplined knowledge issues in self-control, self-control is proved and extended in endurance, and endurance is then joined to godliness (eusebeia), a life ordered reverently toward God. The sequence opposes any claim to spiritual knowledge that lacks sustained moral perseverance, a concern that becomes especially acute in the letter’s portrayal of the libertine false teachers.

The phrase ἐν ἐπιθυμίᾳ μιασμοῦ characterizes these men as walking "after the flesh" in a way governed by corrupt desire and directed toward pollution. The prepositional phrase is compact and emphatic: ἐπιθυμίᾳ (dative singular) functions as the sphere or instrument of their conduct, while μιασμοῦ (genitive singular) qualifies the desire as one aimed at, or marked by, defilement. The construction does not restrict the offense to one isolated category of vice, though sexual immorality is certainly included in Peter's portrayal of false teachers elsewhere in the chapter. The language is broader and moral-theological: they are controlled by appetites that issue in ceremonial and ethical uncleanness, the opposite of covenant holiness. This reading fits the surrounding participles. The clause continues with καταφρονοῦντας, "despising," and then the appositional terms Τολμηταί, αὐθάδεις, and the assertion that they do not tremble at "glories" (δόξας). Peter is not merely cataloging sins but describing a posture of rebellion: fleshly impulse, contempt for authority, audacity, and irreverence. The participial series suggests a settled habitual pattern rather than a single act. The men are "going after" (πορευομένους) the flesh, an idiom of chosen direction, so that defilement is both the path they take and the goal their desires pursue. In canonical terms, such language echoes the Old Testament concern that impurity is not merely external but springs from the rebellious heart, and it anticipates Peter's later contrast between those enslaved by corruption and those who escape it through knowledge of Christ. Here the emphasis falls on the moral inversion produced by false teaching: what should be hated is desired, and what should be honored is despised. The verse thus depicts not only licentious behavior but a deep deformation of moral perception and allegiance.

Peter’s point is not that his own experience on the mountain was unreliable, but that the prophetic word stands as a firmer and more abiding basis for the church’s faith because it is the divinely given interpretation of the glory that the apostles witnessed. The adjective βεβαιότερον (bebaioteron) is best taken in the comparative sense, and the context favors understanding it with the force of confirmed or made more sure rather than merely “more certain” in some abstract sense. Peter has just appealed to the Transfiguration as an event of unique apostolic privilege (1:16–18); now he insists that the prophetic Scriptures, which anticipated and elucidate that glory, are not displaced by experience but confirmed by it. The logic is canonical: the prophetic word and the apostolic testimony do not compete, for the latter verifies the former, while the former provides the norm by which the significance of the latter is understood. The phrase ᾧ καλῶς ποιεῖτε προσέχοντες (“to which you do well to pay attention”) makes the object of continuing attention the written prophetic word, not the mountain event itself. The comparison with a lamp shining “in a dingy place” (λύχνῳ φαίνοντι ἐν αὐχμηρῷ τόπῳ) underscores the present obscurity of the age and the need for an external, divine light until eschatological dawn. Thus the verse does not diminish the apostolic eyewitness; rather, it subordinates extraordinary experience to the inscripturated prophetic witness, which is the church’s settled light until the Day breaks and the “morning star” rises. In classic Reformed terms, Scripture is not authenticated by private experience, but experience is interpreted and judged by Scripture.

Peter’s point is not to speculate on the mechanics by which the voice reached the disciples, but to underscore its origin and revelatory character: “we heard this voice from heaven” (ἐξ οὐρανοῦ). The participle ἐνεχθεῖσαν, an aorist passive from φέρω, is grammatically best taken as modifying “voice” and agreeing with it in case and gender, yielding the sense of a voice “borne,” “conveyed,” or “uttered” from heaven. In context the passive naturally reflects the voice as something given to the disciples rather than generated on the mountain by any human agency. The wording thus heightens the objectivity of the apostolic witness: the testimony was not an inward impression but an external divine utterance received audibly by those present. The phrase σὺν αὐτῷ ὄντες (“while we were with him”) anchors the experience historically in the Transfiguration narrative and distinguishes the apostolic eyewitnesses from later recipients of tradition. Peter’s emphasis falls on shared presence with Christ “on the holy mountain” rather than on esoteric status. The mountain is “holy” not in itself but because of the divine self-disclosure that occurred there, as in other biblical theophanies where a locale becomes set apart by God’s manifestation. The combination of heavenly origin, audible reception, and eyewitness presence serves the larger argument of the paragraph: the apostolic proclamation of Christ’s majesty rests on real events witnessed by those commissioned to speak for him, not on cleverly devised myth.

The syntax strongly suggests that Peter places Paul’s letters in the same category as the "other Scriptures". The relative clause refers back to the δυσνόητά τινα in Paul’s letters, which the unstable twist "as also the rest of the Scriptures" (ὡς καὶ τὰς λοιπὰς γραφάς). The force of καί here is comparative and additive: the same kind of distortion done to Paul’s difficult statements is also done to the wider body of γραφαί. Since γραφή in the New Testament normally denotes sacred Scripture, the most natural reading is that Peter is not merely ranking Paul as a respected teacher, but recognizing his letters as belonging to the sphere of divinely authoritative writings. This observation is important in light of the verse’s own polemical logic. Peter does not say that Paul’s letters are equal to Scripture in every respect of genre or ease of interpretation; rather, he notes that they contain some things δύσνοητα, difficult to grasp, and that those who are ἀμαθεῖς and ἀστήρικτοι mis-handle them to their own ruin. The comparison with "the other Scriptures" assumes a shared vulnerability: both Paul and the established Scriptures can be misread when the reader is morally and doctrinally unsteady. The final phrase, πρὸς τὴν ἰδίαν αὐτῶν ἀπώλειαν, shows that such distortion is not a harmless exegetical mistake but a mode of self-destructive rebellion. A few have tried to soften the force of γραφάς here by taking it as a broader term for "writings" or by limiting it to some non-canonical collection. Yet the idiom, the article, and Peter’s unqualified comparison all favor a canonical sense. The verse therefore provides one of the clearest first-century indications that at least some Pauline correspondence was already being received as Scripture within the apostolic church, even while its interpretation remained susceptible to abuse by the unstable.
