1. I confessed; you forgave (1-6)
David was a king. He was a successful general and a national hero. He was loved and respected by his subjects. He was also a talented musician and poet. But these did not make him happy. When he sinned and tried to cover it up, he became sick. He had no strength. He was miserable. Then he sought God. He confessed his sin, and God forgave him. He found that the happy man is the man whose sins are forgiven, so he urges men to seek God and be happy.
2. The unfailing love of the Lord (7-11)
He found that though his enemies were still many and the burden of his responsibilities was just as great, the Lord was his hiding place. His heart was filled with songs of deliverance. He could rejoice and sing. He realized that he had been like a horse or mule when he had clung to his stubborn pride with an unrepentant heart. Mules have no understanding. They are controlled by the bit and bridle. Those who come to God for forgiveness can rejoice in God.
Application: Lord, I come to you with a repentant heart. Have mercy on me and forgive my sins. Restore the joy of my salvation.
One Word: The forgiven sinner is happy
