1 John 3:20-22

20 For if our heart condemn us, God is greater than our heart, and knoweth all things.
21 Beloved, if our heart condemn us not, then have we confidence toward God.
22 And whatsoever we ask, we receive of him, because we keep his commandments, and do those things that are pleasing in his sight.

vs 20: If we do not forgive ourselves, we lack confidence in God

vs 21: Forgive ourselves, increased confidence in God

vs 22: Answered prayer because of vs 21, and also an increased desire to do and please
