Who shall not fear thee, O Lord, and glorify thy name? for thou alone are holy: for all nations shall come and worship before thee. Rev. 15:4.
Revelation 20 is the only chapter in the Bible where the thousand years, or millennium, is mentioned. Let's read the first six verses of the chapter. "And I saw an angel come down from heaven, having the key of the bottomless pit and a great chain in his hand. And he laid hold on the dragon, that old serpent, which is the Devil, and Satan, and bound him a thousand years, 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.
"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. But the rest of the dead lived not again until the thousand years were finished. This is the first resurrection. Blessed and holy is he that hath part in the first resurrection: on such the second death hath no power."
The beginning of the thousand years is the first resurrection. There is another resurrection at the end. The righteous are raised at the first resurrection, at the coming of Jesus. They are taken to heaven to live and reign with Christ. The wicked are in their graves until the second resurrection a thousand years later. Satan and his cohorts are bound to the earth.
When Jesus comes, the announcement will be made that he that is unjust shall be unjust still, and he that is holy will be holy still. In spite of how much Satan would like us to believe that there will be a second chance, the Bible teaches that there is only one. But until that time, the door is still open. We still have the option of choosing to answer Christ's knock at the door of our hearts, and to prepare to meet Him. There is hope for each person today, as well as for those who have fallen asleep in Jesus. Christ has the power to raise from the dead.
