Psalm 100 (ESV)
100:1 Make a joyful noise to the Lord, all the earth!
2 Serve the Lord with gladness!
Come into his presence with singing!
3 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.
4 Enter his gates with thanksgiving,
and his courts with praise!
Give thanks to him; bless his name!
5 For the Lord is good;
his steadfast love endures forever,
and his faithfulness to all generations.
