Then I saw a beast coming up out of the sea, having ten horns and seven heads, and on his horns were ten diadems, and on his heads were blasphemous names. And the beast which I saw was like a leopard, and his feet were like those of a bear, and his mouth like the mouth of a lion. And the dragon gave him his power and his throne and great authority. I saw one of his heads as if it had been slain, and his fatal wound was healed. And the whole earth was amazed and followed after the beast;
they worshiped the dragon because he gave his authority to the beast; and they worshiped the beast, saying, "Who is like the beast, and who is able to wage war with him?" (Rev. 13)
The beast that you saw was, and is not, and is about to come up out of the abyss and go to destruction. And those who dwell on the earth, whose name has not been written in the book of life from the foundation of the world, will wonder when they see the beast, that he was and is not and will come. Here is the mind which has wisdom. The seven heads are seven mountains on which the woman sits, and they are seven kings; five have fallen, one is, the other has not yet come; and when he comes, he must remain a little while. The beast which was and is not, is himself also an eighth and is one of the seven, and he goes to destruction. (Rev. 17)
7 heads - at the time of this revelation to John, 5 were fallen, the 6th is, and the 7th was yet to come. Then it "is not" and returns as the 8th. It is the head that received the fatal wound and was healed. The great gentile empires (all oppressors of Israel), empowered by Satan the dragon:
all fallen before John
7. Islamic Caliphate
"yet to come" then "fatally wounded"
8. Resurrected Islamic Caliphate
"who is able to make war with him", "goes into destruction" when Christ Himself returns
The ten horns which you saw are ten kings who have not yet received a kingdom, but they receive authority as kings with the beast for one hour. These have one purpose, and they give their power and authority to the beast. These will wage war against the Lamb, and the Lamb will overcome them, because He is Lord of lords and King of kings, and those who are with Him are the called and chosen and faithful. (Rev. 17)
These 10 Islamic kings will have their Caliphate led by their Caliph/Mahdi, but not until the exact time ordained by God. Did you know that attempts to resurrect the Caliphate have been ongoing ever since the Ottoman empire was broken up after WW1 and the office of Caliph abolished by Attaturk? Why hasn't it succeeded yet? I say let's look at the history and see what we find!
(***Did you know why Columbus wanted to find a new route to Asia? Because the Ottomans would not let them through their territory any longer. Do you know why Isabella and Ferdinand only agreed to send him in 1492? In January of that year, they finally drove the Muslim kingdom out of Iberia ending the "Reconquest" for Christianity over Islam. America was only settled because of the Caliphate and only after Islam was removed from Spain.)
2003 - USA invades Iraq after a decade of harassment. Overthrows Hussein and installs democracy. Begins 8 year stalemate battling Iranian Shia and Arab Sunni. America, the greatest military and economic power in world history, seems unable to achieve victory.
2007 - US "surge" of forces beat back both sides and in November 2008, coinciding with election of President Obama, agreement for all US troops to leave Iraq by end of 2011. Door to Caliphate opened.
2013 - As Brotherhood attempted to implement Sharia (as they have always held), military coup topples them. Obama orders his administration to reach a "final status" peace deal with Israelis and Palestinians.
"And those who dwell on the earth, whose name has not been written in the book of life from the foundation of the world, will wonder when they see the beast, that he was and is not and will come."
