16. If anyone should see his brother sinning a sin not leading to death, he should ask, and he will grant life to him, to those who sin not leading to death. (There is a sin leading to death; I do not say that he should ask about that.
17. All unrighteousness is sin, and there is a sin not leading to death.)
18. We know that everyone who is fathered by God does not sin, but the one fathered by God, he protects him, and the evil one does not touch him.
19. We know that we are from God, and the whole world lies in the power of the evil one.
20. And we know that the Son of God has come and has given us understanding, in order that we may know the one who is true, and we are in the one who is true, in his Son Jesus Christ. This one is the true God and eternal life.
21. Little children, guard yourselves from idols.
