'Thousand Years' in the Bible

But you, dear friends, must never shut your eyes to the fact that, to the Lord, one day is the same as a thousand years, and a thousand years as one day.

He seized the Dragon, the primeval Serpent (who is the 'Devil' or 'Satan'), and bound him in chains for a thousand years.

He flung him into the bottomless pit and locked it, and set his seal upon it; that he should not deceive the nations any more, until the thousand years were ended. After that he must be let loose for a while.

Then I saw thrones, and to those who took their seats upon them authority was given to act as judges. And I saw the souls of those who had been beheaded because of the testimony to Jesus and because of the Message of God, for they had refused to worship the Beast or its image, and had not received the brand on their foreheads and on their hands. They were restored to life, and they reigned with the Christ for a thousand years.

(The rest of the dead were not restored to life till the thousand years were ended.) This is the First Resurrection.

Blessed and holy will he be who shares in that First Resurrection. The second Death has no power over them; but they will be priests of God, and the Christ, and they will reign with him for the thousand years.

When the thousand years are ended, Satan will be let loose from his prison,
