An exhortation to praise God cheerfully, 1, 2, for his greatness, 3; and for his power, 4, 5.
1 [A Psalm of Praise.] Make a joyful noise to the LORD, all you lands.
2 Serve the LORD with gladness. Come before his presence with singing.
3 Know that the LORD himself 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.
Matthew Henry Commentary - Psalms, Chapter 100[➚]
John Calvin's Chapter Summary:
The title of this psalm may serve for a summary of its contents Moreover, its brevity renders a lengthened discourse unnecessary. The Psalmist, in an especial manner, invites believers to praise God, because he has chosen them to be his people, and has taken them under his care.
