A psalm of praise
Praises to God are found throughout the Psalms, but Psalm 100 is the only one to be titled, “A Psalm of praise.” Psalm 100 “is all ablaze with grateful adoration, and has for this reason been a great favourite with the people of God,” said Charles Spurgeon. It has given its name to one of the best known melodies in Christian hymnody: "the Old One Hundredth." The tune was used with an adaptation of Psalm 100—“All people that on earth do dwell”— and is also used to sing "The Doxology."
Make a joyful noise unto the Lord, all ye lands.
Serve the Lord with gladness:
come before his presence with singing.
Know ye that the Lord he is God:
it is he that hath made us, and not we ourselves;
we are his people, and the sheep of his pasture.
Enter into his gates with thanksgiving,
and into his courts with praise:
be thankful unto him, and bless his name.
For the Lord is good;
his mercy is everlasting;
and his truth endureth to all generations.
