The Gospel of Revelation
Then I saw another sign in heaven, great and marvelous: seven angels having the seven last plagues, for in them the wrath of God is complete.
And I saw something like a sea of glass mingled with fire, and those who have the victory over the beast, over his image and over his mark and over the number of his name, standing on the sea of glass, having harps of God.
They sing the song of Moses, the servant of God, and the song of the Lamb, saying: “Great and marvelous are Your works, Lord God Almighty! Just and true are Your ways, O King of the saints!
Who shall not fear You, O Lord, and glorify Your name? For You alone are holy. For all nations shall come and worship before You, For Your judgments have been manifested.”
After these things I looked, and behold, the temple of the tabernacle of the testimony in heaven was opened.
And out of the temple came the seven angels having the seven plagues, clothed in pure bright linen, and having their chests girded with golden bands.
Then 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.
The temple was filled with smoke from the glory of God and from His power, and no one was able to enter the temple till the seven plagues of the seven angels were completed.

"a sea of glass mixed with fire", which represents, possibly, the terrible persecution that the Beast will submit to Christians during the period of the Great Tribulation. During this period no man will be able to buy or sell, unless he has engraved in his hand or on his forehead the Mark of the Beast, the number 666.
These days will be very difficult, in which no Christian will survive unless it has been sealed with the Mark of God.
This verse tells us that they will not only endure that period, but that they have achieved victory over the beast and its image and its mark and the number of its name. Here we have the saints of the Tribulation, who have passed through the fire of persecution and yet their song has not ceased. They have the harps of God
This chapter alludes to the preparations that are made for the consummation of the judgment, with the introduction of the seven angels that would pour out the seven bowls, while the seals and the trumpets represent the preliminary judgments, the seven bowls represent the judgments that are to be consummated, and therefore are the last, as indicated by a simile, as a sea of glass mixed with fire recalls the liberation of Israel through the Red Sea, with waters stained by the pillar of fire, also emphasizes the security of the redeemed
It is through the revelation of the Holy Spirit to understand these things that are going to happen, many think Apocalypse with death for the righteous, and in reality it is the fall of Babylon and the eternal enemy.
