Psalm 51 is perhaps one of the most beautiful Psalms in the Bible. It contains David's heartfelt contrition regarding his sin with Bathsheba. In this Psalm, David displays his penitent heart. David's penitent heart was a heart that 1) Acknowledged his sin, 2) Appealed for forgiveness, and 3) Adjusted his attitude. In studying these things we seek to understand the penitent heart so that we can know how to repent of our sins also.
