1 John 5:14-16

RKJNT(i) 14 And this is the confidence that we have in him, that if we ask anything according to his will, he hears us. 15 And if we know that he hears us in whatever we ask, we know that we have that which we have requested of him. 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.
