This study guide gives you questions and leader’s notes for Revelation 15, the short chapter where seven angels receive the final plagues and a crowd of believers sings beside a sea of glass. It works for a small group, a Sunday class, or a quiet personal study. Each set of questions moves from what the text says, to what it means, to how it shapes daily life.
Revelation 15 at a Glance
John sees a new sign in heaven: seven angels holding the last plagues, which bring God’s wrath to completion. Before the angels act, he sees those who have stood firm against the beast gathered by a sea of glass, holding harps and singing the song of Moses and the Lamb. Their song praises God’s works, his justice and his holiness, and it anticipates the nations coming to worship him.
The chapter then shifts to the heavenly temple, which opens and fills with smoke from God’s glory. The angels come out dressed in pure linen, one of the living creatures hands them bowls of wrath, and no one can enter the temple until the plagues are finished. Chapter 15 is a pause and a preparation, a moment of worship before the judgments fall.
Observation Questions
Use these questions first, before anyone offers an interpretation. Ask the group to point to the specific words in the text, and resist the urge to explain too quickly. Let people notice details like colors, objects and actions before moving on.
Revelation 15:1-2
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.

Read these verses first to set the scene of the sign, the angels and the sea of glass. They give the group a clear picture of the chapter’s setting before any discussion begins.
Revelation 15:3-4
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.”
(WEB)
The song is the heart of the chapter, so reading it aloud lets the group hear its praise together. Pause afterward and invite people to name the attributes of God that stand out to them.
Revelation 15:5-6
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.
(WEB)
These verses open the heavenly temple and bring the angels into view. Reading them aloud helps the group picture the moment when judgment is about to be released.
Revelation 15:7
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.
(WEB)
This single verse presents the bowls of God’s wrath, a central image of the chapter. Hearing it alone gives the group space to consider how God’s judgment is handled by his own servants.
Revelation 15:8
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.
(WEB)
Ending with this verse brings the chapter to its pause, with the temple filled with glory and no one able to enter. Reading it last leaves the group in the same expectant silence that John describes.
Memory Verse for Revelation 15
Revelation 15:4
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.”
(WEB)
This verse holds the core of the chapter’s worship: God alone is holy, and all nations will come to worship him. Memorizing it gives you a short prayer to return to whenever you need to recall God’s holiness and faithfulness.
A Closing Prayer for the Group
Father, we come before you as those who are still learning to sing your song in the middle of a broken world. Thank you that your works are great and marvelous, and that your ways are righteous and true. Teach us to praise you when our circumstances are hard, and to trust your timing when we cannot see how your plans will unfold. Help us to stand firm in faith, to resist the pull of idols, and to keep our eyes fixed on your holiness. May our lives become a song of worship that points others to you. Amen.
