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.
10. Now—Now that Satan has been cast out of heaven. Primarily fulfilled in part at Jesus' resurrection and ascension, when He said (Mt 28:18), "All power [Greek, 'exousia,' 'authority,' as here; see below] is given unto Me in heaven and in earth"; connected with Re 12:5, "Her child was caught up unto God and to His throne." In the ulterior sense, it refers to the eve of Christ's second coming, when Israel is about to be restored as mother-church of Christendom, Satan, who had resisted her restoration on the ground of her unworthiness, having been cast out by the instrumentality of Michael, Israel's angelic prince (see on Re 12:7). Thus this is parallel, and the necessary preliminary to the glorious event similarly expressed, Re 11:15, "The kingdom of this world is become (the very word here, Greek, 'egeneto,' 'is come,' 'hath come to pass') our Lord's and His Christ's," the result of Israel's resuming her place.
salvation, &c.—Greek, "the salvation (namely, fully, finally, and victoriously accomplished, Heb 9:28; compare Lu 3:6, yet future; hence, not till now do the blessed raise the fullest hallelujah for salvation to the Lamb, Re 7:10; 19:1) the power (Greek, 'dunamis'), and the authority (Greek, 'exousia'; 'legitimate power'; see above) of His Christ."
accused them before our God day and night—Hence the need that the oppressed Church, God's own elect (like the widow, continually coming, so as even to weary the unjust judge), should cry day and night unto Him.
