1 John 5:14-16

14 And how bold and free we then become in his presence, freely asking according to his will, sure that he's listening.

15 And if we're confident that he's listening, we know that what we've asked for is as good as ours.

16 For instance, if we see a Christian believer sinning (clearly I'm not talking about those who make a practice of sin in a way that is "fatal," leading to eternal death), we ask for God's help and he gladly gives it, gives life to the sinner whose sin is not fatal. There is such a thing as a fatal sin, and I'm not urging you to pray about that.
