Psalms 100: 1 - 3, 5
1 Make a joyful noise to the LORD, all the lands!
2 Serve the LORD with gladness! Come into his presence with singing!
3 Know that the LORD is God! It is he that made us, and we are his; we are his people, and the sheep of his pasture.
5 For the LORD is good; his steadfast love endures for ever, and his faithfulness to all generations.
