Revelation 11:15: And the seventh angel sounded; and there were great voices in heaven, saying, The kingdoms of this world are become the kingdoms of our Lord, and of his Christ; and he shall reign for ever and ever.

The Third Woe will begin when the seventh and final trumpet angel of the seventh seal sounds his trump.¹ The seventh trump symbolically heralds Christ's Second Coming to earth as the King of kings.² The Second Coming will occur at the end of the Third Woe,³ when the kingdom of heaven combines with the kingdom of God on earth.⁴ At that time, great voices in heaven⁵ will joyfully declare⁶ that the kingdoms of this world are become the kingdoms of our Lord [God],⁷ and of his Christ.⁸ Christ will be anointed King at Adam-ondi-Ahman⁹ and at the Second Coming he will establish his new world government.¹⁰ Nebuchadnezzar, the king of Babylon,¹¹ had a dream that foresaw this day when God's kingdom¹² shall make a full end of all nations.¹³

The great voices in heaven are the redeemed of all creation, including exaltation-worthy people who will be resurrected as of the start of the Third Woe and other celestial-worthy creations still awaiting their resurrection in celestial paradise of the postmortal spirit world.¹⁴ John previously described all of creation in celestial paradise as four beasts in Revelation 4:6-8.¹⁵ The great voices also include the 24 Elders from Revelation 4:4, who represent exaltation-worthy saints,¹⁶ as well as the great multitude of exaltation-worthy saints in paradise from Revelation 7:10-17.¹⁷ All these worship God in Revelation 11:16-17.¹⁸

The kingdoms of this world are the component parts of the singular kingdom of Satan.¹⁹ The heavenly hosts proclaim the supremacy of Christ's kingdom over all these worldly kingdoms.²⁰ After the Third Woe, these kingdoms will no longer exist, and Christ shall reign on earth for ever and ever.²¹
