7 And there was war in the heaven: Michael and his angels went to war with the dragon. And the dragon fought, and his angels; 8 and he prevailed not, nor was their place found any more in the heaven. 9 And the great dragon was cast out, the ancient serpent, he who is called Devil and Satan, he who deceives the whole habitable world, he was cast out into the earth, and his angels were cast out with him.

Commentary on Revelation 12:7-11
(Read Revelation 12:7-11)
The attempts of the dragon proved unsuccessful against the church, and fatal to his own interests. The seat of this war was in heaven; in the church of Christ, the kingdom of heaven on earth. The parties were Christ, the great Angel of the covenant, and his faithful followers; and Satan and his instruments. The strength of the church is in having the Lord Jesus for the Captain of their salvation. Pagan idolatry, which was the worship of devils, was cast out of the empire by the spreading of Christianity. The salvation and strength of the church, are only to be ascribed to the King and Head of the church. The conquered enemy hates the presence of God, yet he is willing to appear there, to accuse the people of God. Let us take heed that we give him no cause to accuse us; and that, when we have sinned, we go before the Lord, condemn ourselves, and commit our cause to Christ as our Advocate. The servants of God overcame Satan by the blood of the Lamb, as the cause. By the word of their testimony: the powerful preaching of the gospel is mighty, through God, to pull down strong holds. By their courage and patience in sufferings: they loved not their lives so well but they could lay them down in Christ's cause. These were the warriors and the weapons by which Christianity overthrew the power of pagan idolatry; and if Christians had continued to fight with these weapons, and such as these, their victories would have been more numerous and glorious, and the effects more lasting. The redeemed overcame by a simple reliance on the blood of Christ, as the only ground of their hopes. In this we must be like them. We must not blend any thing else with this.
