1 John 5:16-18

16If anyone sees his fellow Christian committing a sin not resulting in death, he should ask, and God will grant life to the person who commits a sin not resulting in death. There is a sin resulting in death. I do not say that he should ask about that.

17All unrighteousness is sin, but there is sin not resulting in death.

18We know that everyone fathered by God does not sin, but God protects the one he has fathered, and the evil one cannot touch him.
