Revelation 16:17: And the seventh angel poured out his vial into the air; and there came a great voice out of the temple of heaven, from the throne, saying, It is done.

The seven Vial Plagues of the Third Woe¹ will reach their climactic end² when the seventh angel pours out his vial into the air.³ Satan is called the prince of the power of the air.⁴ Therefore, a plague on the air⁵ is an attack on Satan's domain and his dominion.⁶ Satan's power in the air will end⁷ as Christ descends from heaven in glory through the airspace⁸ that Satan can no longer occupy or control.⁹ As the glory of Christ's Second Coming fills the air from the east,¹⁰ the darkness of Satan and his evil host will shrink from his presence.¹¹ The air will also be filled with a righteous army of angels,¹² called the kings of the east in Revelation 16:12.¹³

All evil spirits of devils must be eliminated from the earth as part of the earth's spiritual cleansing.¹⁴ This will occur during the seventh Vial Plague, after God the Father speaks from the throne¹⁵ out of the temple in heaven,¹⁶ saying: It is done.¹⁷ The words of the Father are the antitype¹⁸ for the Savior's final words of victory on the cross when he said, it is finished.¹⁹ After Christ spoke from the cross, there were convulsions and tempests that changed the entire topography of the American continent.²⁰ Similarly, when the Father declares it is done,²¹ the topography of the entire earth will change as it returns to the paradisaical conditions that existed before the fall of Adam.²²
