1. Joyful (vv. 1-2). We can easily understand the people of Israel shouting joyfully in praise to their great God (vv. 3, 5), but the psalmist calls for all the nations of the earth to praise Him. This is a recurring theme in the “royal psalms” (97:1, 6; 98:2-4, 7; 99:1-2), for it was Israel’s responsibility to introduce the Gentiles to the true and living God. The church has been commissioned to take the good news into all the world (Matt. 28:18-20; Mark 16:15), and it will be a glorious day when God’s people gather at His throne from “all nations, and kindreds, and peoples, and tongues” (Rev. 7:9). But our shouting ought to lead to serving Him, for He is the only true God (Deut. 6:13; 10:12; Josh. 24:15-24). Worship leads to service, and true service is worship. If we sing in the Spirit and with understanding, our songs are received in heaven as sacrifices to the Lord (Heb. 13:15).
