Psalm 100 Feb. 25 A Psalm of thanksgiving.  1Shout for joy to Yahweh, all you lands! 2Serve Yahweh with gladness, come before His presence with singing. 3Know that Yahweh, He is God. It is He who has made us and not we ourselves, and we are His. We are His people, and the sheep of His pasture. 4Enter into His gates with thanksgiving, into His courts with praise. Give thanks to Him, and bless His name. 5For Yahweh is good, His grace endures forever, His faithfulness to all generations.   

Commentary

100:3 The fact that God Himself created us, as His sheep, “and not we ourselves” (a comment applicable, in essence, to theories of atheistic evolution) should lead us to ecstatic singing of praise before Him. Likewise 96:2,5, and so many other examples, invite us to enthusiastically praise God, simply because “the Lord made the heavens”. God as creator results in joy and praise amongst those of His creation who recognize Him as creator.
