Revelation 17:7 And the angel said unto me, Wherefore didst thou marvel? I will tell thee the mystery of the woman, and of the beast that carrieth her, which hath the seven heads and ten horns.
8 The beast that thou sawest was, and is not; and shall ascend out of the bottomless pit, and go into perdition: and they that dwell on the earth shall wonder, whose names were not written in the book of life from the foundation of the world, when they behold the beast that was, and is not, and yet is.
The angel wondered why John marveled and tells him he will explain to him about the beast and the woman and the seven heads and ten horns.It talks of the beast that was, the ruler in the first 3 and 1/2, and is not, he is presumed dead midway in the tribulation, and is yet, is the Antichrist appearing to be resurrected like Christ. The last one will be the Antichrist that leads so many to turn from God but those who know the truth will not waver. These whose names were not written in the book of life will wonder after the destruction of in the last half of tribulation about the one that was, and is not , and yet is. They will actually realize they have followed the wrong one but it is too late.Today you still have a chance to make the decision to accept Christ and not have to face the tribulation at all, want you make that decision today?
