Psalm 100:1-5  A psalm. For giving thanks. 
Shout for joy to the LORD, all the earth. 2 Worship the LORD with gladness; come before him with joyful songs. 3 Know that the LORD is God. It is he who made us, and we are his; we are his people, the sheep of his pasture. 4 Enter his gates with thanksgiving and his courts with praise; give thanks to him and praise his name. 5 For the LORD is good and his love endures forever; his faithfulness continues through all generations.
