We had Psalm 100 in the Liturgy this week. It is one of my favorite psalms. It tells us:
"Sing joyfully to the Lord, all you lands; serve the Lord with gladness; come before him with joyful song.
Know the the Lord is God; he made us, his we are; his people, the flock that he tends.
Enter his gates with thanksgiving, his courts with praise; give thanks to him, bless his name.
For he is good: the Lord, whose kindness endures forever, and his faithfulness to all generations."
So, let us today serve the Lord with gladness and come before him joyful and grateful.
