“For God is the King of all the earth; sing praises with a psalm!” (v7). The ancient Israelites rejoiced that God had “subdued” their enemies and given them a wonderful heritage (v3-4). But while national pride would normally stop there, the psalmist pointed toward God’s bigger plan: for “all the earth” to sing praises to the Creator King (v2,7). One day, separation would be no more, because by faith people from every tribe would be included in God’s family through the Son. “The princes of the peoples gather as the people of the God of Abraham” (v9).
“God reigns over the nations” (v8). True human unity is found when people from “every tribe and tongue” joyfully acknowledge Jesus as Lord.
