When the thousand years are over, Satan is released from prison and goes out to deceive millions of people all over the world, gathering them at the beloved city to battle Christ and His army. But fire comes down from heaven and devours them. Satan is thrown into the lake of fire for eternal torment.
Then every dead unbeliever is raised to appear before the Great White Throne for final judgment. Books are opened which show their works. Another book is opened -- the Book of Life. Because their names are not written there, they, too, are thrown into the lake of fire.
