1 Kings 21

"Then another message from the Lord came to Elijah: 'Do you see how Ahab has humbled himself before me? Because he has done this, I will not do what I promised during his lifetime. It will happen to his sons; I will destroy his dynasty.'" v.28-29
Ahab was more wicked than any other king of Israel, but when he repented in deep humility, God took notice and reduced his punishment. The same Lord who was merciful to Ahab wants to be merciful to you. No matter how evil you have ben, its never too late to humble yourself, turn to God, and ask for forgiveness.
