A Psalm for Thanksgiving.

1 Shout joyfully to the Lord, all the earth.
2 Serve the Lord with gladness; Come before Him with joyful singing.
3 Know that the Lord Himself is God; It is He who has made us, and not we ourselves; 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 lovingkindness is everlasting And His faithfulness to all generations. (Psalm 100:1-5)

Known affectionately as "Old Hundredth," this psalm praises Yahweh joyfully, calling all the earth to worship him.
It is not without reason that the Psalmist calls us to worship Yahweh. We should praise Him because of who He is. For He is Lord (v. 1), God (v. 3a), Creator (v. 3b), Shepherd (v. 3d), good (v. 5), merciful (v. 5), and faithful (v. 5).

As well as giving us many reasons to worship Yahweh, the Psalmist tells us how to do it. The Lord wants us to shout with joy (v. 1), serve Him gladly (v. 2), sing before Him (v. 2b), give thanks to Him (v. 4a), and bless His name (v. 4b).

On this Thanksgiving Day, be sure to enjoy time with your family and friends. Eat lots of delicious food. Most importantly, give thanks to God for all these blessings!
