V.1-4 Here is a very important lesson. King David had committed a dreadful sin (2 Sam. 11). Not only in committing adultery, but in causing the husband to be killed. In this Psalm, David takes full responsibility for his sin. He throws himself at the Lord’s feet. All sin is against God.
V.5 He goes back to the root of all sin. When the believer sins he (or she) must go to God quickly and confess it. 1 John 1:9 is important.
V.8-12 He longs to get back to the real joy of life — keeping close to the Lord.
V.13-15 He wants to be able to witness to others about the Lord.
V.16,17 We rest on the one sacrifice for our sins, the death of the Lord Jesus.
V.19 Then the Lord will rejoice too.
