What does Revelation 20:4 mean?
Strictly speaking, the resurrection John sees here involves a specific group of Christians: the martyred believers of the great tribulation. The "first resurrection" includes those who are raised at the rapture (1 Thessalonians 4:16), along with these end-times believers, into eternal life. Those who are part of the "second resurrection," described later, face only judgment (Revelation 20:5; 20:11–15).The apostle Paul wrote in 2 Timothy 2:12 that Christians will reign with Christ. Revelation 2:26–27 promises that overcomers will receive authority over the nations and will rule them with a rod of iron. Also, it appears the armies of heaven will reign with Jesus (Revelation 19:14). The armies are the saints who accompany Christ to the earth. Further, tribulation martyrs will be resurrected to participate in the administration of Christ's earthly kingdom (Revelation 20:4). Based on Daniel 12:1–3, some scholars believe that Old Testament believers will also be raised to rule in this administration.
Whom will these individuals rule? The "sheep" at the judgment of the nations (Matthew 25:33–34) will enter the kingdom in their physical bodies. Many of them will procreate, and the cycle of birth will continue during the kingdom reign. Each generation will come under the rule of God's people. Although righteousness will prevail, sin will erupt occasionally and require the judicial attention of those who reign with Christ (Isaiah 65:20; Zechariah 5:3–4).
Revelation 20:4–10 focuses on the reign of Christ during the millennium: the thousand years of Christ's rule on earth, as well as what happens at the end of that era. The millennial reign begins after the Devil is imprisoned in the bottomless pit (Revelation 20:1–3) and before the unrighteous dead of all periods of history are judged and consigned to the lake of fire (Revelation 20:11–15). These events precede the descent of the New Jerusalem from heaven (Revelation 21).
Revelation chapter 20 represents the final lesson, final judgment, and final victory of the end times. Satan is bound, but not destroyed, and released after a thousand years of peace and righteousness. Proving that no evidence or reason to believe in and follow Jesus is enough for those determined to rebel, some follow Satan and are destroyed in a rebellion. Those who died without faith in Christ, through all of history, are resurrected to face the great white throne judgment. There, they are sentenced for sin and consigned eternally to the lake of fire.
