17 Every unrighteousness is sin; and there is a sin not to death.
18 We know that every one begotten of God does not sin, but he that has been begotten of God keeps himself, and the wicked one does not touch him.
19 We know that we are of God, and the whole world lies in the wicked one.
20 And we know that the Son of God has come, and has given us an understanding that we should know him that is true; and we are in him that is true, in his Son Jesus Christ. He is the true God and eternal life.
21 Children, keep yourselves from idols.
