1 John 5:14-16

VIN(i) 14 This is the confidence that we have toward him: that if we ask anything according to his will he hears us. 15 And if we know that he hears us, whatever we ask, we know that we have the requests that we have asked of him. 16 If anyone sees his brother commit a sin that does not lead to death, he will ask, and God will give him life for those whose sin is not leading to death. There is sin leading to death. I do not say that he should pray about that.
