1 John 5:16-18

16If any one see his brother sinning a sin not unto death, he shall ask, and he shall give him life, for those that do not sin unto death. There is a sin to death: I do not say of that that he should make a request.

17Every unrighteousness is sin; and there is a sin not to death.

18We know that every one begotten of 1God does not sin, but he that has been begotten of 2God keeps himself, and the wicked [one] does not touch him.
