Then I saw an angel coming down from heaven with the key to the Abyss, holding in his hand a great chain. He seized the dragon, that ancient serpent who is the devil and Satan, and bound him for a thousand years. And he threw him into the Abyss, shut it, and sealed it over him, so that he could not deceive the nations until the thousand years were complete. After that, he must be released for a brief period of time. Then I saw the thrones, and those seated on them had been given authority to judge. And I saw the souls of those who had been beheaded for their testimony of Jesus and for the word of God, and those who had not worshiped the beast or its image, and had not received its mark on their foreheads or hands. And they came to life and reigned with Christ for a thousand years. The rest of the dead did not come back to life until the thousand years were complete. This is the first resurrection. Blessed and holy are those who share in the first resurrection! The second death has no power over them, but they will be priests of God and of Christ, and will reign with Him for a thousand years. When the thousand years are complete, Satan will be released from his prison, and will go out to deceive the nations in the four corners of the earth—Gog and Magog—to assemble them for battle. Their number is like the sand of the seashore. And they marched across the broad expanse of the earth and surrounded the camp of the saints and the beloved city. But fire came down from heaven and consumed them. And the devil who had deceived them was thrown into the lake of fire and sulfur, into which the beast and the false prophet had already been thrown. There they will be tormented day and night forever and ever.
And I will put enmity between you and the woman, and between your seed and her seed. He will crush your head, and you will strike his heel."
Significance
Revelation 20 narrates the consummated head-crushing of Genesis 3:15. The angel "seized the dragon, that ancient serpent (ὁ ὄφις ὁ ἀρχαῖος) who is the devil and Satan, and bound him for a thousand years" (20:2), and at the last "the devil who had deceived them was thrown into the lake of fire and sulfur... tormented day and night forever and ever" (20:10). The repeated title "that ancient serpent" — carried over from 12:9 — explicitly equates this enemy with the serpent of Eden, so the binding and final destruction of Satan are the terminus of the protoevangelium. What Genesis 3:15 announced as a promised wound to the serpent's head, and what Calvary accomplished decisively (Heb 2:14), Revelation 20 brings to its eschatological end: the serpent is not merely defeated but permanently removed from God's renewed creation. The trajectory is complete — garden curse, cross-victory, consummation. The asymmetry of Genesis 3:15 reaches its maximum here: the serpent's striking is over forever, while the crushing of his head is irreversible and eternal. The telos is the final security and gladness of the redeemed: the believer's longing for a world free of the deceiver is answered absolutely — never again will the serpent rise to ruin Eden, for the seed of the woman has cast him into the fire, and the saints reign with Christ in a kingdom from which evil is forever banished.
