Assurance of Eternal Life and Warnings Against Sin
1 John 5:13-21
13These things I wrote to you so that you may know that you have eternal life, to those who trust in the name of the Son of God.14And this is the boldness which we have toward him, that if we ask anything according to his will, he hears us.15And if we know that he hears us, whatever we ask, we know that we have the requests which we have asked from him.16If anyone sees his brother sinning a sin not toward death, he will ask, and he will give him life—to those sinning not toward death. There is sin toward death; I do not say that one should ask about that.17All unrighteousness is sin, and there is sin not toward death.18We know that everyone who has been begotten of God does not sin, but the one begotten of God keeps him, and the evil one does not touch him.19We know that we are of God, and the whole world lies in the evil one.20We know, moreover, that the Son of God has come and has given us a mind so that we may know the true one; and we are in the true one, in his Son Jesus Christ. This is the true God and eternal life.21Little children, guard yourselves from the idols.
