1 John 5:16-18

RKJNT(i) 16 If any man sees his brother commit a sin which does not lead to death, he shall ask, and God shall grant him life, for those whose sin is not to death. There is a sin to death: I do not say that he should pray for that. 17 All unrighteousness is sin, and there is a sin that does not lead to death. 18 We know that whoever is born of God does not sin; but he who was begotten of God keeps him, and the wicked one does not touch him.
