“And the ten horns which thou sawest are ten kings, which have received no kingdom as yet; but receive power as kings one hour with the beast” (Rev: 17:10).
“For God hath put in their hearts to fulfill his will, and to agree, and give their kingdom unto the beast, until the words of God shall be fulfilled” (Rev 17:17).
The Bible predicts that someday a world leader will emerge from a revived Roman Empire. The European Union is clearly the fulfillment of this prophetic event. At some point, ten leaders will come to rule the EU. The likely reason for the ten political bosses is the need to streamline the decision making process. When the EU grows to 25 nations, it will become quite clear that a central governing body will be necessary. The book of Revelation tells us that the ten kings and the Beast (Antichrist) will rule at the same time. It looks like the current timeline and the prophetic timeline are about to join up with each other.
At this time, the leadership of the European Union rotates among its member nations, shifting to a new EU president every six months. I see it as a kind of musical chairs game: Who will get that last, all important chair when the music stops playing?
