Create in me a clean heart, O God, and put a new and right spirit within me. Do not cast me away from your presence, and do not take your holy spirit from me. Restore to me the joy of your salvation, and sustain in me a willing spirit.—Psalm 51:10–12 Most of us have wished at one time or another that life had a “do-over” button (or an “unsend” button for e-mail). This was true even of King David, the second king of Israel, whom God called “a man after my heart” (Acts 13:22).

Then Peter came and said to him, “Lord, if another member of the church sins against me, how often should I forgive? As many as seven times?” Jesus said to him, “Not seven times, but, I tell you, seventy-seven times.”
—Matthew 18:21–22
