1 Make a joyful shout to the Lord, all you lands!
2 Serve the Lord with gladness;
Come before His presence with singing.
3 Know that the Lord, He is God;
It is He who has made us, and not we ourselves;
We are His people and the sheep of His pasture.
4 Enter into His gates with thanksgiving,
And into His courts with praise.
Be thankful to Him, and bless His name.
5 For the Lord is good;
His mercy is everlasting,
And His truth endures to all generations.
This psalm gives us many reasons to praise God. In the middle of numerous exhortations to praise Him, the unidentified writer lifts up the following attributes of God that should compel one to praise Him. First, He is God. That should be enough on its own. God signifies an awesome presence, higher and holier than anyone. He is then identified as the Creator of the world, especially mankind. He is also lauded as the Shepherd of His people, One who nurtures and protects. Fourth, He is called good. As you recall, Jesus said there is none good, no not one. However, God is good, always good, forever good. Fifth, God is eternal in His mercy, reaching to every generation equally with the offer of forgiveness of sin. Sixth and finally, God’s truth endures to all generations, making Him eternally true.
When the reader takes in all the attributes of God listed here, it is clear why the psalmist admonishes the reader to shout joyfully, serve the Lord, and sing His praises. It is reasonable to offer thanksgiving and praise and to be thankful. Our God is praiseworthy and we should give Him praise!
