20:1 And I saw an angel come down from heaven, having the key of the bottomless pit and a great chain in his hand. 00343 20:2 And he laid hold on the dragon, that old serpent, which is the Devil, and Satan, and bound him a thousand years, 00344 20:3 And cast him into the bottomless pit, and shut him up, and set a seal upon him, that he should deceive the nations no more, till the thousand years should be fulfilled: and after that he must be loosed a little season. 00345 20:4 And I saw thrones, and they sat upon them, and judgment was given unto them: and I saw the souls of them that were beheaded for the witness of Jesus, and for the word of God, and which had not worshipped the beast, neither his image, neither had received his mark upon their foreheads, or in their hands and they lived and reigned with Christ a thousand years. 00346 20:5 But the rest of the dead lived not again until the thousand years were finished. This is the first resurrection.
Rev. 20:4-6 is also great. And I believe it. However, John wrote in symbols and OT imagery. While I don't believe anyone can actually say exactly what this part of the passage has to say, we can say that we do know what constitutes the first resurrection (see my post #24 on the thread "The Millennial Syndrome"). The "rest of the dead", along with the dead saints of the thousands of years, will be raised from the dead, the living translated and caught up with Christ, the unbelievers raised for judgment - the second death.
