What does Psalm 33:4 mean?
The first two of several reasons for praising the Lord with joy appear in this verse. First, God's Word is true. When Jesus prayed to the Father in His High Priestly Prayer, He asked that believers be sanctified in the truth, adding, "your word is truth" (John 17:17). In his letter to Titus, Paul affirms that God is incapable of lying. He states categorically that God never lies (Titus 1:2). Psalm 119:142 declares that the Lord's law is true, and verse 160 affirms, "The sum of your word is truth."According to this verse, everything God does is dependable. All the Lord's works are performed in faithfulness. Whatever the Lord does exhibits His unfailing care. This description comes from a Hebrew word which also refers to "trustworthiness" or "honesty." The Lord God makes no mistakes. We may trust Him, therefore, to orchestrate all the events in our lives for our good and His glory (Romans 8:28–30).
Psalm 33:4–19 records David's reasons to praise the Lord. They include praise for God's Word, His creative power, His sovereignty over the nations, His all-seeing vision, His faithful works, and His deliverance of His people.
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.
