and behold a white horse; and he that sat upon it was called Faithful and True, and in righteousness he does judge and make war. 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. And he was clothed with a robe dipped in blood: and his name is called The Word of God.
And the armies which were in heaven followed him upon white horses, clothed in fine linen, white and clean.
And out of his mouth goes forth a sharp sword, that with it he should smite the nations: and he shall rule them with a rod of iron: and he treads the winepress of the fierceness and wrath of Almighty God. And he has on his robe and on his thigh a name written, KING OF KINGS, AND LORD OF LORDS.
And I saw an angel standing in the sun; and he cried with a loud voice, saying to all the fowls that fly in midheaven, Come and gather yourselves together unto the supper of the great God; That you may eat the flesh of kings, and the flesh of captains, and the flesh of mighty men, and the flesh of horses, and of them that sit on them, and the flesh of all men, both free and slave, both small and great.
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. And the beast was taken, and with him the false prophet that worked miracles before him, with which he deceived them that had received the mark of the beast, and them that worshiped his image. These both were cast alive into a lake of fire burning with brimstone. And the rest were slain with the sword of him that sat upon the horse, which sword proceeded out of his mouth: and all the fowls were filled with their flesh. Revelation 19:11-21
This will literally happen very soon. The time is near. When Jesus comes He will slaughter a vast proportion of the population. Certainly, the political and religious leaders are the first on His hit list, it says here. The earth will be filled with rotting dead bodies and the birds will be filled eating their flesh.
The scenario here of Jesus and His army coming down onto the earth and being met by a gathering of armies coming to fight against Him, is amazing to me. We need to remember that Jesus is a Man. He is returning as the crucified and risen, flesh and bone Man, Christ Jesus. He will set foot on the Mount of Olives. He will lead a real army of His saints from heaven (those of us who were faithful to Him) onto the earth. It will be a real battle. Real birds will eat the corpses of the fallen.
