2 And I saw what appeared to be a sea of glass mingled with fire, and those who had conquered the beast and its image and the number of its name, standing beside the sea of glass with harps of God in their hands. 3 And they sing the song of Moses, the servant of God, and the song of the Lamb, saying, "Great and wonderful are thy deeds, O Lord God the Almighty! Just and true are thy ways, O King of the ages! 4 Who shall not fear and glorify thy name, O Lord? For thou alone art holy. All nations shall come and worship thee, for thy judgments have been revealed."
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.
