1We ask you, brothers, concerning the coming of our Lord Jesus Christ and our gathering to him.2We ask that you not be quickly shaken from the mind nor alarmed, neither through spirit nor through word nor through an epistle as though from us, as if the day of the Lord is present.3Let no one deceive you in any way, because that day will not come unless the apostasy comes first and the man of lawlessness is revealed, the son of destruction.4He opposes and exalts himself above all that is called god or object of worship, so that he sits in the temple of God, displaying himself as God.5Do you not remember that while I was still with you I told you these things?6And now you know the one holding back, toward the revealing of him in his own time.7For the mystery of lawlessness is already at work; only the one holding back now until he comes to be out from the midst.8And then the lawless one will be revealed, whom the Lord Jesus will kill with the breath of his mouth and bring to nothing by the appearance of his coming.9His coming is according to the active energy of Satan, in all power and signs and wonders of falsehood.10His coming is also in all deceit of unrighteousness for those perishing, because they did not receive the love of the truth so that they might be saved.11Therefore God sends them a powerful delusion so that they believe the lie.12They are to be condemned, all who did not believe the truth but took pleasure in unrighteousness.
