What does Psalm 38:22 mean?

David's plight (Psalm 38:1–4, 8, 18) created a sense of urgency. He prays for God to act quickly, to restore David and relieve him of his misery. God's conviction and correction can be deeply painful to endure; yet this is part of God's mercy, since that pain drives us to repentance and reconciliation with Him. A sense of urgency can drive a believer to call upon the Lord for help. Hebrews 4:16 encourages this, saying, "Let us with then with confidence draw near to the throne of grace, that we may receive mercy and find grace to help in time of need."

The disciple Peter sensed his urgent need to be rescued from heavy waves that threatened his life. When he attempted to walk on water, then began to sink, he urgently appealed for rescue (Matthew 14:30). Jesus answered Peter's urgent call immediately. He reached out His hand and took hold of him (Matthew 14:31).

Here, David addresses God as "my [his] salvation." He correctly recognized that only the Lord could deliver him from his sin, his suffering, and his enemies. Even while humbly admitting his sin, and expressing his pain, David was faithfully confident that the Lord would hear his prayer.
