1I saw an angel coming down out of heaven, having the key of the abyss and a great chain in his hand. 2He seized the dragon, the old serpent, who is the devil and Satan, who deceives the whole inhabited earth, and bound him for a thousand years, 3and cast him into the abyss, and shut it and sealed it over him, that he should deceive the nations no more until the thousand years were finished. After this, he must be freed for a short time.
4I saw thrones, and they sat on them, and judgment was given to them. I saw the souls of those who had been beheaded for the testimony of Jesus and for the word of God, and such as didn’t worship the beast nor his image, and didn’t receive the mark on their forehead and on their hand. They lived and reigned with Christ for a thousand years. 5The rest of the dead didn’t live until the thousand years were finished. This is the first resurrection. 6Blessed and holy is he who has part in the first resurrection. Over these, the second death has no power, but they will be priests of God and of Christ, and will reign with him one thousand years.
7And after the thousand years, Satan will be released from his prison 8and he will come out to deceive the nations which are in the four corners of the earth, Gog and Magog, to gather them together to the war, whose number is as the sand of the sea. 9They went up over the width of the earth and surrounded the camp of the saints and the beloved city. Fire came down out of heaven from God and devoured them. 10The devil who deceived them was thrown into the lake of fire and sulfur, where the beast and the false prophet are also. They will be tormented day and night forever and ever.
11I saw a great white throne and him who sat on it, from whose face the earth and the heaven fled away. There was found no place for them. 12I saw the dead, the great and the small, standing before the throne, and they opened books. Another book was opened, which is the book of life. The dead were judged out of the things which were written in the books, according to their works. 13The sea gave up the dead who were in it. Death and Hades gave up the dead who were in them. They were judged, each one according to his works. 14Death and Hades were thrown into the lake of fire. This is the second death, the lake of fire. 15If anyone was not found written in the book of life, he was cast into the lake of fire.
3:1 Sardis, located 30 miles southeast of Thyatira, had been the capital of Lydia. The worship of the Roman Caesar and of Artemis, goddess of fertility, were active here. The seven Spirits may be the Holy Spirit, or perhaps seven angels ( 1:4 ). The seven stars are “the angels of the seven churches” ( 1:20 ).
3:2 No one’s works are completely perfect before God (see Rom 3:23 ). Unbelievers, those whose names are not “written in the Book of Life” ( Rev 20:15 ), will be judged solely according to their works ( 20:12 , 13 ).
3:3 Christ’s warning that He will come unexpectedly as a thief echoes His repeated emphasis in Matt 24:36-25:13 : Be alert and ready for My coming ( Rev 16:15 ).
3:4 Those who have not defiled their garments are those who have remained faithful to Christ. Unlike some of the believers, they have had victory over sin and have demonstrated a practical righteousness. The Lord promises those who have not defiled their garments that they will walk with Him in white, for they are worthy. This image probably describes righteous acts, not the imputed righteousness of Christ ( 19:8 ).
3:5 The white garments probably symbolize the Lord’s recognition of godly character and faithful service in this life (v. 4 ; 6:11 ; 19:7 , 8 ). White is the color of the garments the redeemed will wear in the Lord’s presence ( 7:13 , 14 ). The Book of Life is the list of the eternally redeemed ( 20:12 , 15 ). To not blot out is a figure of speech, affirming a positive by negating its opposite. Thus it means “I will include their names.” Blot out likely alludes to Exod 32:32 , 33 , where God says He will blot out sinners, but not faithful ones like Moses, from His Book. Christ will make sure the faithful believer’s name and works are not erased, but remembered and honored. Confess his name before My Father and before His angels: The text does not state that any believer will have his name blotted out of the Book of Life (see Luke 10:20 ). Rather, the faithful believer will be resoundingly confessed before the saints, the angels, and the Father by the Son (see Matt 10:32 , 33 ; 2 Tim 2:12 ). To have the Lord publicly confess one’s name is to have the Lord’s approval of one’s character and service (see Matt 10:32 , 33 ; 1 Tim 2:12 , 13 ).
