Now, in the formation of the anti-Christian kingdom, God gives the Euphrates River – which is the dividing line between the East and the West – to dry up. This barrier between these two is removed. The way is clear, therefore, in the text for the kings of the East to join now with the West. The anti-Christian kingdom is going to overcome this natural barrier between East and West, and he will join all nations of the earth together.
Those unclean spirits that go forth accomplish this union under the providence of God, deceiving the nations to join together. Revelation 16:13 speaks of three unclean spirits like frogs going forth from the unholy copycat trinity of the dragon (who is Satan), the beast (who is the political anti-Christian world power) and the false prophet (which is the false and apostatizing church). These unclean spirits are pictured as frogs, because frogs are repulsive and disgusting, and these unclean spirits are spiritually repulsive and disgusting. They go forth to the whole earth – including to the East – to convince the nations of the world to join as one with the anti-Christian power. The throne of Antichrist is in the West, where false and apostatizing Christianity takes the lead in propping up this anti-Christian kingdom. That false and apostatizing Christianity leads all the nations of the world – the kings of the East too – to join this kingdom. These unclean spirits don't, of course, remove all distinctions between East and West, but through the influence of what comes out of their mouth and the possibility of wealth and pleasure and the promise of safety, it causes the kings of the East to join – to overcome that barrier and go beyond the Euphrates River and join this worldwide anti-Christian kingdom.
The purpose of this union, from the point of view of the Antichrist and of the men of the earth who receive the mark of the beast, is that the world be united in the service of man. That man's depraved nature finally be able to loose itself completely without fear. That God and His law be dethroned completely in the earth and man and his desires be enthroned completely in all the earth. That is the Antichrist’s purpose with this union and with the sending out of those unclean spirits. But that is not God’s ultimate purpose! The pouring out of the sixth vial gives us the rise of the Antichrist from God's point of view. That is something that we have not talked about yet in great detail in this series.1

13 And I saw, coming out of the mouth of the dragon and out of the mouth of the beast and out of the mouth of the false prophet, three unclean spirits like frogs.
