What does Psalm 33:20 mean?
One of the ways we demonstrate faith in God is by "waiting on" Him. Those who can truthfully speak the words of this verse have learned several good reasons to wait on the Lord. They know He is faithful and will not disappoint them. Their hope in Him is firm. They trust God as their advocate and ultimate defense. Hebrews 4:16 directs believers to approach God with confidence, knowing He offers us patient mercy. Likewise, God is a protector to those who trust Him. Even if earthly struggles are overwhelming, nothing can eternally defeat those whose shield is the Lord (John 16:33)!God's schedule does not always match ours. We prefer immediate answers to prayer, but the Lord is never in a rush. He is not obligated to respond immediately, but He has promised He will answer, "in time of need" (Hebrews 4:16). Literally "waiting" for the Lord to send us an answer teaches us to depend on Him, as well as grows our patience and trust.
Psalm 33:20–22 completes David's song with an expression of faith in the Lord. The congregation and choir, having recounted the many reasons to praise the Lord, confess their peace, hope, and trust in God. They ask Him to place His steadfast love upon them.
David summons the worshipers of Israel to be joyful as they praise God. The psalm celebrates God's creative power, sovereignty, and faithfulness. Rather than relying on earthly strength, the Lord's people can trust in His omnipotent power. This results in a collective praise for God and His unfailing love for those who trust and hope in Him.
