Of these 7 kingdoms, 5 are prior to John’s prophecy, 1 present to him and 1 is yet future. Moreover, the 7th kingdom is predicted to manifest for “a short space.” Interestingly, there is an 8th kingdom. This is the beast himself, obviously rising up in his own right from the restraint placed upon him
The 4th kingdom was still in place in the first century. Rome is the 4th kingdom. The 5th kingdom is the ten toes.
If you say that 5 kingdoms are past, that would be the time since the Reformation until the Second Coming. This period we are in, today, is the 6th kingdom.
That would destroy your idealistic view that Satan is bound in the 4th kingdom. Satan is of all earthly kingdoms, and always influential in them, never bound once in history.
"And there are seven kings: five are fallen, and one is, and the other is not yet come; and when he cometh, he must continue a short space. And the beast that was, and is not, even he is the eighth, and is of the seven, and goeth into perdition."
Satan, the beast is of the 7, not including the 7th. The seven are the first 6 and the 8th. The 8th kingdom makes "of the seven".
We are in the 6th kingdom now. The one where the stone without hands crushed the image of earthly kingdoms. Jesus as Prince is the 7th kingdom after the Second Coming. The 8th kingdom is Satan's 42 months where he sits on the throne of Jesus in Jerusalem.
Post tribulationist incorrectly give the 7th kingdom to a false messiah. They are the ones claiming here is Christ and there is Christ, instead of acknowledging the True Prince, Jesus Christ.
Satan is the beast that has been around since tempting Eve in the Garden. Satan has been involved in all earthly kingdoms working and pulling the strings, of whoever follows him. Satan has not been simply incarcerated ever. Only the kingdoms he thinks he has been in charge of have been invaded by the Gospel. When Satan is bound, he will not have any influence period. Unlike amil's pseudo incarceration.
So saying 5 kingdoms have fallen would not place the writing in the first century. Because the 4th kingdom Rome had not past yet. Revelation 4 and after is clearly written in the context of today (the future of the first century). This would be after the 5th kingdom, the ten toes, was replaced by the 6th kingdom.
What is presented in Revelation 13:1-4 as a beast is human government, not an individual beast. Satan is the individual beast. There is a third beast referenced along with Satan and the false prophet. So the term beast is not just one entity throughout the book, but different depending on context.
The beast in Revelation 13:1 is not necessarily the same beast in Revelation 17:3. The one in Revelation 17 is describing that 8th kingdom, of which Satan has 100% control over. The contrast in Revelation 17:9 with Revelation 17:10 is that verse 9 is describing the then current governmental situation, with the historical past of all earthly kingdoms in verse 10. If not, then there is nothing in Revelation looking back on history, but all beast only describe a post Second Coming scenario, and only if Satan is even given 42 months to set up an earthly Babylonian empire after the decimation of the Second Coming.
