Good Morning Davy,
Why would you choose to disregard(unbelief) God's words?
Then I saw the beast and the kings of the earth with their armies assembled to wage war against the One seated on the horse, and against His army.
But the beast was captured along with the false prophet, who on its behalf had performed signs deceiving those who had the mark of the beast and worshiped its image.
Both the beast and the false prophet were thrown alive into the fiery lake of burning sulfur.
What you're not understanding is that the 'beast' and 'false prophet' concepts are ROLES that Satan will play as false-Messiah when he comes. This is why all three, the beast, false prophet, and the dragon (Satan) are shown working the miracles to deceive with; it's all the same source, Satan as the beast king.
Rev 19:20
20 And the beast was taken, and with him the false prophet that wrought miracles before him, with which he deceived them that had received the mark of the beast, and them that worshipped his image. These both were cast alive into a lake of fire burning with brimstone.
KJV
Who's "image" did they worship? Satan, the "dragon", as the "another beast" of Rev.13:11 forward that will set up the "image of the beast" in false worship, and work miracles and speak lies like waters as a flood to deceive at the end.
Rev 16:10
10 And the fifth angel poured out his vial upon the seat of the beast; and his kingdom was full of darkness; and they gnawed their tongues for pain,
KJV
Who's "kingdom"?? The beast's kingdom. Who is that? Satan, the "dragon" and beast king. It's his kingdom.
Rev 16:13
13 And I saw three unclean spirits like frogs come out of the mouth of the dragon, and out of the mouth of the beast, and out of the mouth of the false prophet.
KJV
The unclean spirits come out of all three, the dragon, the beast, and the false prophet. It's because all three ROLES are about the beast king Satan, also called the "dragon."
Rev 16:14
14 For they are the spirits of devils, working miracles, which go forth unto the kings of the earth and of the whole world, to gather them to the battle of that great day of God Almighty.
KJV
They are from the "dragon", Satan, the "another beast", the pseudo-Christ, man of sin, that will work the great signs and wonders to deceive the whole world, except Christ's elect.
How do those beast and false prophet Roles compare with Satan's coming attempt to mimic our Lord Jesus Christ? Lord Jesus is a Prophet per Deut.18:15; contrasted with Satan as the "false prophet". Lord Jesus is The KING; contrasted with Satan as the beast king.
