Psalm 33

Shout for joy in the Lord, O you righteous!” The writer of this psalm was not specifically identified, though he was leading the Lord’s people in worship. He was calling on all of those who were gathered in God’s presence to sing and to play musical instruments—not just for their own pleasure—but with the joyful awareness that the Lord God was listening to them.
The Lord’s people had many good reasons to praise their God. The psalmist began with the greatness of God’s Word. “The Word of the Lord is upright.” The God who spoke that Word was Himself the epitome of all that was right and good. He was also powerful. His Word brought about the creation of the heavens and the earth. That Word also ordered and sustained everything that God had created.
Other impressive rulers throughout the earth might make plans against the will of the God of Israel, but would they be able to overrule the decrees of the Almighty? Certainly not! The Lord could easily frustrate even the most frightening tyrants. Israel was greatly blessed to have the Lord as their God.
The Lord exercised supreme power from His throne above. He also enjoyed complete knowledge of the smallest details of every creature upon the earth. “He sees all the children of man.” He also knew everything they did or even intended. He knew the hearts of every king and all their subjects. He had His eye of protection and mercy on all those who approached Him with reverent fear. He was able to help them in their times of greatest need.
The Lord was wonderful in every way! His power, knowledge, and love were beyond compare. Yes, Israel had every reason to shout for joy to the Lord. If worship was right for them, how can we who know the Lord Jesus Christ do less than they were called to do? Our Savior is the eternal Word of God. He has been given all power and authority in heaven and on earth. His goodness and love are beyond question. He Himself is the best reason that we can ever have to respond to God’s invitation to worship Him.
