What does Psalm 3:8 mean?

David concludes this psalm by declaring that salvation belongs to the Lord. That understanding enables him to express confidence in the Lord to deliver him from his enemies, and he ascribes all the credit to the Lord. Although David refers to deliverance from his enemies (2 Samuel 17:1–4; 15–16) as "salvation," here, Scripture teaches that eternal salvation from sin and perdition also belongs exclusively to the Lord. God saves by grace; that is, undeserved favor. Ephesians 2:8–9 teaches: "For by grace you have been saved through faith. And this is not your own doing; it is the gift of God, not a result of works, so that no one may boast." Romans 6:23 also teaches us that salvation is a gift from God. This verse states, "For the wages of sin is death, but the free gift of God is eternal life in Christ Jesus our Lord."

David pronounces a benediction as he closes Psalm 3. He prays that the Lord's blessing will rest upon His people. This benediction reveals David's shepherd heart. He thinks about and prays for the well-being of the people of Israel despite his difficult personal circumstances.
