They were holding God’s harps, and they sang the song of Moses, the servant of God, and the song of the Lamb: “Great and wonderful are your works, Lord God almighty. Just and true are your ways, O king of the nations.
Who will not fear you, Lord, or glorify your name? For you alone are holy. All the nations will come and worship before you, for your righteous acts have been revealed.” (Rev 15:1-4)

The liturgy of heaven continues with the Song of the Lamb. I grew up in a church where music was important. I even sang in the children’s choir. And I can still remember the songs we sang. Music is one way we come to God. As the hymn says, “Lift every voice and sing, Till earth and heaven ring!”
