Christ's return is not future?
This is Christ returning and bringing his armies with him.
Revelation 19:11 "And I saw heaven opened, and behold a white horse; and he that sat upon him was called Faithful and True, and in righteousness he doth judge and make war."
Revelation 19:12 "His eyes were as a flame of fire, and on his head were many crowns; and he had a name written, that no man knew, but he himself."
Revelation 19:13 "And he was clothed with a vesture dipped in blood: and his name is called The Word of God."
Revelation 19:14 "And the armies which were in heaven followed him upon white horses, clothed in fine linen, white and clean."
The beast is preparing to battle against him, so this is indeed future.
Revelation 19:19 "And I saw the beast, and the kings of the earth, and their armies, gathered together to make war against him that sat on the horse and against his army.
Revelation 19:20 "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 like of fire burning with brimstone."
How is this not future? Christ has just returned. And the beast and FP that deceived them with the mark of the beast are thrown into the lake of fire.
