What does Psalm 62:7 mean?

This psalm frequently repeats the metaphor of God as a "rock." The implication is that of safety and security. Anchoring a structure to solid rock gives it the best possible foundation (Luke 6:48). Fortresses—both in the ancient world and more recently—are frequently built on rocky terrain and composed of rock-like materials. Thick stone walls radiate a sense of power and security, far more than wood or soil. God can keep David completely safe from his enemies, so David can experience calm in the face of danger (Psalm 62:1–2, 5–6).

Further, David calls attention to the Lord's power, calling God "mighty." David places all his trust for salvation in the Lord alone. In the same way, David relies on God to guide whatever will happen in his life. His "glory"—David's success and accomplishments—are grounded in his relationship with God.

A key teaching of Scripture is that salvation is anchored in God alone. No person can earn their way into heaven by adding up good deeds or avoiding bad ones (Ephesians 2:1–10). Attaining eternity with the Lord (Romans 6:23) happens only when a person humbly, submissively depends on God's faithfulness, rather than on their own efforts (Titus 3:5). Further, whatever credit there might be for a believer's success should be credited to the God who made it possible. Colossians 3:4 promises: "When Christ who is your life appears, then you also will appear with him in glory." God deserves all the credit for the believer's salvation and glory.
