"And I heard a great voice in heaven saying: 'Now have come the salvation and the power and the kingdom of our God, and the authority of his Anointed One, because there has been cast down the accuser of our brothers, who night and day accuses them before God. They have overcome him through the blood of the Lamb and through the word of their witness, and they did not love their soul to death. Rejoice, therefore, you heavens and you who dwell in them. Alas for the earth and the sea! because the Devil has come down to you with great wrath and well aware that he has only a little time left.'"
THE REASONS FOR REJOICING AND SINGING
This passage is referring to the glorified martyrs. They rejoice and sing when Satan is cast out of heaven because:
(1) Salvation is at last complete. The singers are in heaven and they will never have to see Satan's ugly face again. Before this event, Satan paraded around in heaven acting like he still belonged there. He was full of himself and accusing God's children of his lies and reminding them of the sins that Father God had removed as far as the East is from the West. God said that when we receive Jesus' blood sacrifice, our sin goes into God's Sea of Forgetfulness. Satan was there to accuse, but Jesus was there to intercede for us, defending us and reminding Father God that His blood has covered our sins.
(2) All power belongs to Jesus and there will be no more evil or the stench of Satan's presence as he visits heaven.
(3) The kingdom of God will shortly come to earth, and
(4) Jesus will at last exercise the authority over earth that He won at the cross.
THE SLEEPLESS VIGIL OF EVIL
The historical background of the age in which the Revelation was written lends sharpness to this picture of Satan. People were constantly being arrested, tortured, killed because someone had informed against them. Tacitus, writing some years before John was given the Revelation, had said: "He who had no foe was betrayed by his friend." That ancient world knew only too well what malevolent, cynical, venal accusers were like. Satan is the poster boy for the sleepless vigilance of evil against good. This passage reveals what could be termed as the cleansing of heaven. Satan, the lying evil prideful Accuser, is cast out forever. It is for this reason that the martyrs in glory sing their song of triumph.
THE POWER IS IN THE BLOOD
The Blood of Jesus fights for His people. When we realize this we have no confidence in ourselves as human beings. Instead, we come to Calvary and point to the Cross - for that is where Jesus paid for our sin with His holy blood. When we sin we break fellowship with God - the only way back into fellowship is repentance and the blood of Jesus will cover the sin. If a person daily beats himself up for his sins, then he is denying what Jesus did for him. You can't do it and also have Jesus do it. Jesus did it ALL. All to Him I owe. It is not any of our goodness that covers the awful mountain of sins that we have done. I John 1:9 says, "If we confess our sins, He is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness." Verse 7 says, "If we walk in the light, as He is in the light, we have fellowship one with another, and the blood of Jesus Christ His Son cleanses us from all sin." So the Blood of Jesus fights for us. We overcome evil by the Blood and by the Word of our testimony.
