Revelation 15 (WEB)

1 I saw another great and marvelous sign in the sky: seven angels having the seven last plagues, for in them God’s wrath is finished.

2 I saw something like a sea of glass mixed with fire, and those who overcame the beast, his image, and the number of his name, standing on the sea of glass, having harps of God.

3 They sang the song of Moses, the servant of God, and the song of the Lamb, saying, “Great and marvelous are your works, Lord God, the Almighty! Righteous and true are your ways, you King of the nations.

4 Who wouldn’t fear you, Lord, and glorify your name? For you only are holy. For all the nations will come and worship before you. For your righteous acts have been revealed.”

5 After these things I looked, and the temple of the tabernacle of the testimony in heaven was opened.

6 The seven angels who had the seven plagues came out, clothed with pure, bright linen, and wearing golden sashes around their breasts.

7 One of the four living creatures gave to the seven angels seven golden bowls full of the wrath of God, who lives forever and ever.

8 The temple was filled with smoke from the glory of God, and from his power. No one was able to enter into the temple, until the seven plagues of the seven angels would be finished.

Summary

John sees another great sign in heaven: seven angels with the seven last plagues, in which the wrath of God is brought to completion. Before they go forth, he sees a sea of glass mingled with fire, and standing beside it those who had conquered the beast, its image, and the number of its name, holding harps given by God. They sing the song of Moses, the servant of God, and the song of the Lamb—joining the old deliverance at the Red Sea to the new deliverance in Christ. Their song magnifies God's great and marvelous works, his righteous and true ways as King of the nations, declaring that all nations will come and worship before him because his righteous acts have been revealed. Then the heavenly temple of the tabernacle of testimony is opened, and the seven angels come out clothed in pure bright linen with golden sashes. One of the four living creatures gives them seven golden bowls full of the wrath of the eternal God, and the temple is filled with smoke from the glory and power of God, so that no one can enter until the seven plagues are finished. The chapter pairs the worship of the redeemed with the solemn preparation of God's final judgments.

Lessons Learned

  • Those who overcome the beast are brought to victory and worship by God's grace.
  • The song of Moses and the Lamb unites God's saving acts across the whole of Scripture.
  • God's judgments are praised as great, marvelous, righteous, and true.
  • God's holiness and glory stand behind every act of his final judgment.
  • Victory ends in worship. Those who overcame the beast stand with “harps of God” (Revelation 15:2, WEB). The triumph of the saints overflows into praise.
  • God's works are marvelous. “Great and marvelous are your works, Lord God, the Almighty!” (Revelation 15:3, WEB). His deeds, even in judgment, evoke wonder, not just fear.
  • His ways are righteous and true. “Righteous and true are your ways, you King of the nations” (Revelation 15:3, WEB). God's judgments are never arbitrary or unjust.
  • All nations will worship him. “All the nations will come and worship before you” (Revelation 15:4, WEB). God's righteous acts draw the peoples to himself.
  1. Why do those who conquered the beast respond with singing rather than mere relief?
  2. What does it mean that they sing both the song of Moses and the song of the Lamb?
  3. How does this song describe God's character and his ways with the nations?
  4. Why might heaven pause to worship just before the final plagues are poured out?
  5. How can praising God's righteous and true ways shape the way you view his judgments?
  1. The victors do not merely escape the beast; they are brought to a place of worship beside the sea of glass (15:2-3). Help the group see that the goal of salvation is not only deliverance but glad, grateful praise of God.
  2. Joining the song of Moses to the song of the Lamb ties the exodus deliverance to the greater rescue in Christ (15:3). Discuss how the whole Bible tells one story of God redeeming his people and how we sing it together.
  3. The song praises God as Almighty, righteous, true, and King of the nations whom all peoples will worship (15:3-4). It centers not on the saints' achievement but on God's character and the revelation of his righteous acts.
  4. Heaven worships before the bowls are poured because God's judgments flow from his holiness and faithfulness, not cruelty. The pause assures us that even his severest acts are worthy of praise, grounded in his righteous and glorious nature.
  5. This is a personal-application question. Invite members to wrestle honestly with God's judgment, then to anchor their thoughts in the conviction that his ways are righteous and true. As leader, encourage trust in God's justice even where it troubles us.
