Rebellion in Heaven

        In the Revelation John says, "And there was war in heaven." We are accustomed to the idea that this earth only has been in a state of rebellion; but this scripture says that 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 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. And I heard a loud voice saying in heaven, Now is come salvation and strength, and the kingdom of our God and the power of His Christ; for the accuser of our brethren is cast down, which accused them before our God day and night." Revelation 12:7-10
        "Michael and His angels fought." Michael is Christ. Three very simple scriptures will show us that. "Yet Michael the archangel, when contending with the devil, He disputed about the body of Moses, durst not bring against him a railing accusation, but said, The Lord rebuke thee." Jude 9.
        There we find that Michael is spoken of as the archangel. And in Thessalonians Paul says, "For the Lord Himself shall descend from heaven with a shout, with the voice of the archangel." 1 Thessalonians 4:16.
        The Lord Himself shall descend with the voice of the archangel. But we read in John 5:25, "Verily, verily, I say unto you, The hour is coming and now is, when the dead shall hear the voice of the Son of God, . . . and shall come forth."
        Michael is the archangel; the Lord will descend with the voice of the archangel; and it is the Lord's voice that calls the dead from their tombs.
        "And the dragon was cast out, that old serpent." Not in the sense that we use the expression—that old serpent himself—but that ancient serpent, that one that caused the trouble in Eden. There was war in heaven, and the old serpent, the one that caused trouble in Eden, and is still causing trouble here, raised the rebellion, led in the fight, and was cast down to the earth.
        Is there any way by which we can tell what caused the trouble in heaven?
