And in James it is said that if we resist the Devil he will flee from us; and in First John we are told that he that committeth sin is of the Devil, for the reason that the Devil sinneth from the beginning; and we are also told that "for this purpose was the Son of God manifested, that he may destroy the works of the Devil."
No Devil—no Christ.
In Revelation, the insanest of all books, I find the following: "And there was war in heaven. Michael and his angels fought against the dragon, and the dragon fought and his angels.
"And prevailed not; neither was their place found any more in heaven.
"And the great dragon was cast out, that old serpent, called the Devil, and Satan, which deceiveth the whole world: he was cast out into the earth, and his angels were cast out with him.
"Therefore, rejoice, ye heavens, and ye that dwell in them. Woe to the inhabiters of the earth and of the sea; for the devil is come down unto you, having great wrath, because he knoweth that he hath but a short time."
From this it would appear that the Devil once lived in heaven, raised a rebellion, was defeated and cast out, and the inspired writer congratulates the angels that they are rid of him and commiserates us that we have him.
In the twentieth chapter of Revelation is the following:
"And I saw an angel come down from heaven, having the key of the bottomless pit and a great chain in his hand.
"And he laid Hold on the dragon—that old serpent, which is the Devil and Satan—and bound him a thousand years.
