Jesus is just and will bring sin to its end

Those who rejoice in God’s justice (15:1-4)

Then I saw another great and awe-inspiring sign in heaven: seven angels with the seven last plagues; for with them God’s wrath will be completed. I also saw something like a sea of glass mixed with fire, and those who had won the victory over the beast, its image, and the number of its name, were standing on the sea of glass with harps from God. They sang the song of God’s servant Moses and the song of the Lamb: Great and awe-inspiring are your works, Lord God, the Almighty; just and true are your ways, King of the nations. Lord, who will not fear and glorify your name? For you alone are holy. All the nations will come and worship before you because your righteous acts have been revealed.
(Revelation 15:1-4)

Those who receive God’s justice (15:5-16:21)

After this I looked, and the heavenly temple—the tabernacle of testimony—was opened. Out of the temple came the seven angels with the seven plagues…
(Revelation 15:5-6)

Then I heard a loud voice from the temple saying to the seven angels, “Go and pour out the seven bowls of God’s wrath on the earth.”
(Revelation 16:1)

Then the seventh poured out his bowl into the air, and a loud voice came out of the temple from the throne, saying, “It is done!”
(Revelation 16:17)
