My Grandmother Ruby's favorite Psalm of Thanks. My Dad, Aunts and Uncles were all required to memorize it as children:
"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 prasie; 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 (NIV)
