What does Psalm 54:7 mean?

When betrayed by enemies and pursued by Saul (1 Samuel 23:19–20), David prayed for rescue (Psalm 54:1–3). This was immediately followed by his confident declaration that the Lord would keep him safe, take vengeance on the evil ones, and bring David safely back to worship in the sanctuary (Psalm 54:4–6).

Among the reasons David is so confident is prior experience. God had already delivered him from dangers and allowed him to look in triumph on his enemies. Of course, David would still face many troubles and battles before taking his rightful place on the throne of Israel, but his faith was strong. He regarded the ultimate victory as having been accomplished already. Many believe David also wrote Psalm 118. There, the psalmist testifies, "The Lᴏʀᴅ is on my side as my helper; I shall look in triumph on those that hate me" (Psalm 118:7).

Christians, too, are victors by the Lord's grace. Paul writes about the troubles that assail believers (Romans 8:36), but adds, "In all these things we are more than conquerors through him who loved us" (Romans 8:37). Someday, believers will return from heaven to earth with the Lord Jesus Christ and share in His victory over evildoers. Although they will not engage the enemy, they will witness Jesus' triumph (Revelation 19:11–21).
