1 John 5:14-15

5:14 And this is the confidence that we have before him: that whenever we ask anything according to his will, he hears us. 5:15 And if we know that he hears us in regard to whatever we ask, then we know that we have the requests that we have asked from him.

1 John 4:6

4:6 We are from God; the person who knows God listens to us, but whoever is not from God does not listen to us. By this we know the Spirit of truth and the spirit of deceit.
