Davy, you were claiming that the beast-king is not a human being. But he will be a human being possessed by the spirit of the serpent beast (that will come out of the bottomless pit).
That is how many interpret it according to their 'carnal flesh thinking.'
But that 'carnal' interpretation is only based on Scripture like Mark 8:31-33 where Peter rebuked Lord Jesus for His saying He would be rejected and crucified, and then Jesus rebuked Peter while referring to Satan speaking through Peter.
It is this, and the events of demons in The New Testament, which causes many to think Satan cannot manifest with his image of man in our earthly dimension, but can only work behind another flesh person, like a spirit possession. Those who think that are relying on a carnal understanding, and don't actually understand the two different dimensions of existence at all that God created, nor how Satan's working at the end of this world is going to be different.
The "strong delusion" which God is going to send upon this world for the coming "great tribulation" will involve Satan and his angels coming here on earth, in OUR EARTHLY DIMENSION, in plain sight. Satan has the image of man, as all angels do. That event of his future coming with His angels is solidly written in the Revelation 12:7-17 Chapter involving the war in Heaven between Archangel Michael and his angels, vs. Satan and his angels. It says when that war happens, there will be no more place found in heaven for Satan. Since there are only TWO different dimensions of existence written of in God's Word, this earthly one we live in, and the heavenly one where God and the angels dwell, and even Satan and his angels dwell, that means there is only one other... place Satan and his angels can go when they are kicked out of heaven, and that is into OUR EARTHLY dimension, right here on earth in plain sight.
That is why in Revelation 17:8 says all those who dwell on earth whose names were not written in the book of life from the foundation of this world, will WONDER AT THAT BEAST (Satan). They will wonder who he is, which is a pointer to the world being able to actually SEE Satan with the image of man right here on earth, working those great signs and wonders and miracles to deceive the whole world. Only Christ's elect will not 'wonder', and will know who he is really is.
