William Graham addresses the critical topic of repentance, using the story of King David's sin with Bathsheba as a backdrop. He emphasizes that true repentance begins with God's conviction and is not merely feeling sorry for being caught in sin. Graham highlights the importance of recognizing the foolishness of sin, the need for self-indictment, and the visible expression of repentance in our lives. He calls for a heartfelt return to God, urging listeners to confess their sins and make God the hero of their stories through genuine repentance.
