I memorized Psalm 100 as a child. It is one of the few chapters of the Bible that I can quote from memory to this day, and it’s always been a favorite.
Make a joyful noise to the Lord, all the earth!
Serve the Lord with gladness!
Come into his presence with singing!
Know that the Lord, he is God!
It is he who made us, and we are his;
we are his people, and the sheep of his pasture.
Enter his gates with thanksgiving,
and his courts with praise!
Give thanks to him; bless his name!
For the Lord is good;
his steadfast love endures forever,
and his faithfulness to all generations.
