"One of the major themes of the Revelation is the conflict between God and Satan, which manifests itself in the history of the conflict between Christ and Antichrist. In the final sections describing the triumph of Christ, John firsts set for the triumph of Christ over Antichrist and his supporters, which is depicted in terms of a great battle, and then the triumph of Christ over Satan himself, which takes place in two stages: his binding in the abyss and his destruction in the lake of fire…The victory over Antichrist necessarily includes a victory over kings and nations of the earth who have given their support and allegiance to Antichrist. This is the battle of Armageddon, announced at the sounding of the sixth trumpet (16:12-16), when demonic spirits gathered the kings of the earth in allegiance to Antichrist “on the great day of God Almighty.”
