Sing joyfully to the LORD, all you lands;
serve the LORD with gladness;
come before him with joyful song.
Know that the LORD is God;
he made us, his we are;
his people, the flock he tends.
Enter his gates with thanksgiving,
his courts with praise;
Give thanks to him; bless his name.
The LORD is good:
the LORD, whose kindness endures forever,
and his faithfulness, to all generations.
(Psalm 100 1-2, 3-5)
Psalm 100 A hymn inviting the people to enter the Temple courts with thank offerings for the God who created them.
100:1–3. This series of imperatives shows that the psalmist is eager to have his invitation accepted. “Serve the Lord” (v. 2) is the equivalent of “Worship him”, but it also implies keeping his commandments. Praise of God, if sincere, is always accompanied by joy (to be seen here in festivity: v. 2; cf. Ps 30; 106; etc.) and it stems from faith (“the Lord is God”: cf. Deut 4:35, 39) and from the conviction that we belong to him and feel safe when he is our guide (v. 3). Eusebius of Caesarea makes this exhortation: “If we do not serve him with joy, we can never dare to come into his presence” (Commentaria in Psalmos, 99) and St Augustine, for his part, says: “This psalm of praise commands and exhorts us to rejoice in the Lord. But it does not command a particular part of the world or one house or people to sing the praises of God; rather, since he pours out his blessings over the whole world, all peoples in all places should rejoice” (Enarrationes in Psalmos, 99, 2).
100:4–5. The “gates” of the Lord are those in the temple (this psalm is thought to have had a liturgical origin). The triple profession of faith in v. 5 corresponds to the triple proclamation of the Lord’s power and love in v. 3.
How do we approach worship in our lives? The worship that the psalm initiates is joyful, full of exuberance, enthusiasm, and mirth. Does this describe your worship experience? We can learn much from this psalm as its call for joy is not hype but a focus on God to whom the praise is directed. These are the qualities of we should yearn for in our worship because: “(1) God is present, and it is possible to enter the very presence of the LORD, it is the exciting anticipation of being in the presence that funds the joy of praise; (2) the God who is present is the shepherd of his people. The LORD is savior. The gathered faithful move into the presence of the one who is ‘for us’; (3) the God who is present is ‘good’ (v. 5) and this is the sole basis for our call to worship.”
May the virtues of faith, hope, and love go with you today – DV.
