The big picture
The Book of Revelation introduces the seven last plagues as the completion of divine wrath, yet before any bowl is poured it shows those who have overcome the beast, its image, its mark, and the number of its name. They stand by a glasslike sea mingled with fire and sing a song called both the song of Moses and the song of the Lamb. Their victory is not described as military conquest but as faithful refusal of the beast's claims. Their song praises God's works, justice, truth, holiness, and the coming worship of the nations. Then the temple of the tabernacle of testimony opens in heaven. Seven angels emerge in pure linen, receive golden bowls from one of the living creatures, and stand while smoke from God's glory fills the sanctuary. No one can enter until the plagues are completed. Covenant language, worship, and judgment remain joined at the threshold of the final sequence.
Central truth
Revelation 15 presents victorious worship before the final plagues, joining the song of Moses and the Lamb with the solemn opening of the heavenly sanctuary from which seven bowls of wrath proceed.

What to explain, in order
Teach the passage in this order. Each step names the verses it rests on, so every point can be shown in the text before it is applied.
Revelation 15:1
The last plagues announced
Open with verse 1 and explain that it acts as a heading for chapters 15 and 16. Seven angels with seven last plagues: the third and final series after the seals and the trumpets. Explain "filled up" as completed: these plagues bring God's judgement on evil to its end. Remind the group that the seals touched a fourth and the trumpets a third. Then tell them that before a single bowl is poured, the chapter will turn aside to a song. That order is the lesson: worship comes before wrath, and God's people see his justice from the place of victory.
Revelation 15:2
Victors beside the sea
Describe the scene. The sea of glass from 4:6 is now mingled with fire, and on it, or beside it, stand those who overcame the beast. Read Exodus 14:29 to 15:1: Israel stood beside the Red Sea after crossing it, saw Pharaoh's army destroyed, and sang. The victors here have come through the beast's sea and stand safe. List their four victories against chapter 13: beast, image, mark and number. Explain that in Revelation victory often looks like death to the world (12:11), and that their harps show the outcome: they are worshipping.
Revelation 15:3-4
One song for Moses and the Lamb
Read Exodus 15:1-18 aloud before the song of verses 3 and 4. Then read the song and show how it is woven from the Old Testament: great and marvellous works from Psalm 111:2 and 139:14, just and true ways from Deuteronomy 32:4, all nations coming to worship from Psalm 86:9 and Jeremiah 10:7. Point out that it names Moses as "the servant of God" and Jesus as the Lamb, and that the singers say nothing about themselves. Explain "King of saints": many ancient copies read King of the nations, which fits verse 4. The song makes the coming judgement the revelation of God's justice.
Revelation 15:5-7
The sanctuary opened
Explain "the temple of the tabernacle of the testimony" as the heavenly original of the tent Moses built, where the tablets of the testimony were kept in the ark (Exodus 25:16, 38:21). The angels come out dressed like priests, in white linen and golden girdles, and receive seven golden bowls, the vessels of temple worship. Note that the bowls in 5:8 held the prayers of the saints; now golden bowls hold God's answer to those prayers. One of the living creatures who led worship in chapter 4 hands them over. Judgement comes from God's holy presence and his covenant faithfulness.
Revelation 15:8
Smoke fills the temple
End with the smoke of glory. Read Exodus 40:34-35 and Isaiah 6:4. God's presence fills the sanctuary so fully that no one can enter. Explain that this marks a decisive moment: until the plagues are complete, no one goes in. Readers often take this as the end of the time of intercession for those who have refused God. Teach it soberly. The chapter that began with a song ends with silence and smoke, and the bowls are about to be poured. Prepare the group for chapter 16 by keeping both pictures in view: the victors' song and the closed sanctuary.
Where learners get stuck
The misreadings this passage tends to produce, and how to answer each from the text.
"Christians sing because their enemies are being destroyed."
The song of 15:3-4 never mentions enemies or the singers' own victory. It praises God's works, his just and true ways, his holiness and the worship that all nations will bring him. Its hope is that "all nations shall come and worship before thee" (15:4). Like Israel's song in Exodus 15, it celebrates God's deliverance from oppression, not delight in suffering. Teach the song as worship of God's justice, not as gloating.
"The song of Moses belongs to the Old Testament, and Christians have moved beyond it."
Revelation joins them in one song: "the song of Moses the servant of God, and the song of the Lamb" (15:3). The exodus is not left behind but fulfilled in the Lamb, whose death is the true Passover (1 Corinthians 5:7). The song itself is built from the Psalms, Deuteronomy and Jeremiah. The New Testament church sings with Israel's Scriptures, not instead of them.
"God's wrath means he loses his temper."
In this chapter the wrath is carried by angels dressed as priests, out of a sanctuary filled with God's glory (15:6-8), and the song calls God's ways "just and true" (15:3). Wrath here is God's settled and holy opposition to evil, carried out with order and justice, not an outburst. The prayers of the saints for justice (6:10, 8:3-5) are being answered. Let learners see that a God who did not oppose evil would not be good.
Learning objectives
- Explain why the seven plagues are called last.
- Describe the victorious worshipers by the glassy sea.
- Identify the song's major claims about God.
- Trace worship into the opened temple.
- Explain the smoke-filled sanctuary in verse 8.
- Separate chapter 15's preparation from chapter 16's bowls.
Teacher preparation
- Read Exodus 15 for the song-of-Moses background.
- Mark sea, fire, beast, song, nations, temple, bowls, wrath, and smoke.
- Compare the two victory songs without making them identical.
- Keep chapter 16's bowl details out of this lesson.
- Let the smoke carry weight without turning it into a joke.
Evidence and interpretation checks
Explicit
Verse 1 calls the seven plagues the last because in them the wrath of God is filled up.
Scripture-supported
Verses 2 to 4 describe those victorious over the beast, image, mark, and number standing on a glassy sea mingled with fire, holding God's harps and singing.
Strong inference
The combination 'song of Moses' and 'song of the Lamb' strongly frames the victory as both exodus-shaped deliverance and Lamb-centered redemption without erasing either biblical horizon.
Possible or traditional reading
Some readers treat the sea of glass and fire primarily as symbolic, while others expect a literal heavenly feature corresponding to John's vision; the chapter does not explain its material nature.
Limit
Revelation 15 does not describe what is inside each bowl, identify every worshiper beyond the victory language of verse 2, or permit the reader to skip directly to catastrophe and ignore the song.
Discussion with answer guidance
1. What makes the sign in verse 1 'great and marvellous'?
What a good answer contains
John sees "another sign in heaven, great and marvellous, seven angels having the seven last plagues; for in them is filled up the wrath of God" (15:1). The sign is great because of what it completes: these are the last plagues, and God's wrath against evil reaches its full measure. A strong answer notes the word "last": the seals and trumpets were partial, and this is the end of the series. It also notes that the same words, great and marvellous, are used of God's works in 15:3. A weak answer stops at the spectacle.
Show teacher guidance
Tie the description to seven angels with seven last plagues and the completion of God's wrath rather than to visual spectacle alone.
2. Who stands on the sea of glass in verse 2, and what have they gained victory over?
What a good answer contains
John sees "them that had gotten the victory over the beast, and over his image, and over his mark, and over the number of his name, stand on the sea of glass, having the harps of God" (15:2). Four victories, matching the four threats of chapter 13. A good answer notices that they hold harps, not weapons, and that their victory is the refusal to worship, often at the cost of their lives (13:15). The sea of glass of 4:6 is now "mingled with fire", recalling the sea Israel crossed. A weak answer assumes they won by fighting.
Show teacher guidance
List beast, image, mark, and number of his name, then notice they hold harps rather than weapons.
3. Which divine qualities dominate the song in verses 3 and 4?
What a good answer contains
"Great and marvellous are thy works, Lord God Almighty; just and true are thy ways, thou King of saints" (15:3). Then: "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" (15:4). A strong answer collects God's great works, his just and true ways, his unique holiness, the worship of all nations and his judgements revealed. It notes that the song is entirely about God; the singers never mention themselves.
Show teacher guidance
Collect great and marvelous works, just and true ways, holiness, universal fear and glory, and judgments made manifest.
4. Why is the song called both the song of Moses and the song of the Lamb?
What a good answer contains
They "sing the song of Moses the servant of God, and the song of the Lamb" (15:3). Exodus 15 is the song Moses and Israel sang beside the sea after God destroyed Pharaoh's army. Here the victors stand beside a heavenly sea after the beast has been overcome. A good answer explains that the two titles describe one song: the exodus deliverance and the Lamb's redemption are the same kind of salvation, and the Lamb's is its fulfilment. It notes that the Passover lamb stood at the heart of the first exodus. A weak answer treats them as two songs in competition.
Show teacher guidance
Use Exodus 15 as background and Revelation's Lamb theme as foreground; present the combination as a deliberate scriptural joining, not a competition.
5. What comes out of the opened heavenly temple in verses 5 and 6?
What a good answer contains
John sees that "the temple of the tabernacle of the testimony in heaven was opened" (15:5). Then "the seven angels came out of the temple, having the seven plagues, clothed in pure and white linen, and having their breasts girded with golden girdles" (15:6). A strong answer notices that they come from God's own presence, dressed like priests and like the Son of man in 1:13. Then a living creature gives them "seven golden vials full of the wrath of God" (15:7). The judgement comes from the holiest place, not from cruelty.
Show teacher guidance
Seven angels bearing seven plagues emerge clothed in pure bright linen with golden girdles; keep the agents and their commission together.
6. What prevents entry into the temple in verse 8, and for how long?
What a good answer contains
Verse 8 says "the temple was filled with smoke from the glory of God, and from his power; and no man was able to enter into the temple, till the seven plagues of the seven angels were fulfilled" (15:8). A good answer recalls Exodus 40:34-35, where Moses could not enter the tabernacle because of the glory, and 1 Kings 8:10-11 and Isaiah 6:4. It sees that the time for intercession has passed until the judgement is complete. A weak answer treats the smoke as a disaster rather than as God's glory.
Show teacher guidance
Smoke from God's glory and power fills the temple, and no man can enter until the seven angels' plagues are fulfilled.
Responsible application
Sing before analyzing the bowls
Let verses 3 to 4 establish God's works, ways, holiness, and judgments first.
Victory is measured by allegiance
Use verse 2 to define conquest through refusal of the beast's worship and mark.
Treat judgment without embarrassment or relish
Teach divine wrath plainly without softening it or enjoying suffering as spectacle.

Sing it
Choose one application. Read the key verse, give out the handout, and if the group sings, close with a hymn of God's justice and holiness.
Adapting the lesson
Children
Tell the children about Moses and the people singing after God brought them safely through the sea. Then tell them that John saw God's people standing by a shining sea, holding harps and singing. Read 15:3-4 and teach a simple line to say or sing together: great and marvellous are your works. Leave out the details of the bowls.
Youth
Ask what song they would sing if they had been rescued from something. Read Exodus 15 and then Revelation 15:3-4. Point out that the song is all about God. Talk about what it means to be victorious over the beast, often by refusing to go along with the crowd, at a cost.
Adults
Trace the exodus pattern through the chapter carefully, with Exodus 14, 15, 25 and 40. Discuss the relation between worship and justice, and why the saints can praise God's judgements. Address the question of wrath with care, and let the chapter's own words, just and true, frame it.
One to one
Ask the person what God has brought them through. Read 15:2-4 and let them hear their own deliverance in the song. If they struggle with the idea of God's wrath, read 15:3 slowly and talk about a God whose ways are just and true.

Revelation 15
The passage in brief
Revelation 15 introduces seven angels with the seven last plagues, which complete God's judgement. But first John sees those who overcame the beast standing beside a sea of glass mixed with fire, holding harps. They sing the song of Moses and the song of the Lamb, praising God's great works and his just and true ways. Then the heavenly temple opens, the angels receive seven golden bowls, and the temple fills with the smoke of God's glory.
A verse to keep
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.
