Shout for joy to the LORD, all the earth.
  Worship the LORD with gladness;
   come before him with joyful songs.
 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.

 Enter his gates with thanksgiving
   and his courts with praise;
   give thanks to him and praise his name. 

 For the LORD is good and his love endures forever;
   his faithfulness continues through all generations.

-Psalm 100

This particular Psalm has been popping up around me lately.
