What does Revelation 17:11 mean?
The angel's explanation of John's symbolic vision (Revelation 17:1–6) continues by focusing on the beast. Varied interpretations of Revelation tend to converge here and identify this specific creature as the Antichrist. The beast had a past but not a present: it "was," but it "is not." However, it will emerge from the seventh form of government and take its place as the eighth form of government. It will be destroyed, though. The most likely interpretation of this passage is as a reference to the seventh form of Roman government, in this case the Revived Roman Empire which comes into existence at the beginning of the tribulation. Ten kings will govern this political structure, but the beast from the sea (Revelation 13:1), will succeed these kings and become the dictatorial head of the Revived Roman Empire.This takeover will introduce the eighth form of Roman government. The eighth form of Roman government will end when the beast—the head of the Revived Roman Empire—is cast into the lake of fire at the hands of Jesus, the King of kings and Lord of lords. Revelation 19:20 says, "And the beast was captured, and with it the false prophet who in its presence had done the signs by which he deceived those who had received the mark of the beast and those who worshiped its image. These two were thrown alive into the lake of fire that burns with sulfur."
Revelation 17:7–14 explains the meaning of the visions John saw in the prior verses. The angel speaking with John explains the symbols of the beast, seven mountains, and ten horns. In the passage to follow, the angel will explain the downfall of the ''great prostitute,'' who symbolizes an ungodly religion. Other passages in the Bible speak to this vision in Revelation 17. e For example, Daniel 7 prophesies a ''fourth empire'' to produce ten kings and another king. The final king will speak blasphemous words against God and will wear out God's saints for three and a half years. However, the Most High will destroy him and establish God's everlasting kingdom. Daniel 9:24–27 and Revelation 13 also describe this defiant, powerful king. Revelation 19:11–21 reveals his end.
Revelation 17 zeroes in on God's judgment of Babylon as the center of religious corruption in the tribulation. The target of this wrath seems to be an eclectic form of all apostate religions. This might be a concrete, single religion. Or, it might be a near-religious blending or equalizing of all spiritual beliefs. God views religious Babylon as ''the great prostitute'' that has support from heads of state. This system is both extremely rich and murderous, guilty of martyring saints. It has a past and a renewed existence as a religious-political system. Together, the political heads of state and religious Babylon battle Jesus, the Lamb, but He defeats them. The end of religious Babylon comes when the ten kings turn against her and ruin her. They destroy religious Babylon because God puts it in the hearts to do so.
