2 I saw something like a sea made of glass, the glass all shot through with fire. Carrying harps of God, triumphant over the Beast, its image, and the number of its name, the saved ones stood on the sea of glass. 3 They sang the Song of Moses, servant of God; they sang the Song of the Lamb: Mighty your acts and marvelous, O God, the Sovereign-Strong! Righteous your ways and true, King of the nations! 4 Who can fail to fear you, God, give glory to your Name? Because you and you only are holy, all nations will come and worship you, because they see your judgments are right.
Matthew Henry's Commentary on Revelation 15:2-4
Commentary on Revelation 15:1-4
(Read Revelation 15:1-4)
Seven angels appeared in heaven; prepared to finish the destruction of antichrist. As the measure of Babylon's sins was filled up, it finds the full measure of Divine wrath. While believers stand in this world, in times of trouble, as upon a sea of glass mingled with fire, they may look forward to their final deliverance, while new mercies call forth new hymns of praise. The more we know of God's wonderful works, the more we shall praise his greatness as the Lord God Almighty, the Creator and Ruler of all worlds; but his title of Emmanuel, the King of saints, will make him dear to us. Who that considers the power of God's wrath, the value of his favour, or the glory of his holiness, would refuse to fear and honour him alone? His praise is above heaven and earth.
