"And they sing the song of Moses the servant of God, and the song of the Lamb, saying, Great and marvellous are Thy works, Lord God Almighty; just and true are Thy ways, thou King of saints. Who shall not fear Thee, O Lord, and glorify Thy name? for Thou only art holy: for all nations shall come and worship before Thee; for Thy judgments are made manifest" Rev 15:3-4
They sing of
God's Work - Great and marvellous are Thy works
God's Ways - just and true are Thy ways
God's Wonder - Who shall not fear Thee, O Lord, and glorify Thy name?
God's Worship - all nations shall come and worship before Thee
God's Wrath - Thy judgments are made manifest
