Revelation 20 shows the moment in history when God will destroy all that is evil once and for all. He will put an end to death, and judge all humanity by what they have done. 

Everyone who has ever lived will stand before the great white throne to be judged by God.

Those who refused to worship God as the creator of heaven and earth, will be judged by what they have done. But those who have believe in the Good News of Jesus Christ, will not be judged by their deeds, because they have been forgiven, and their names are in the Book of Life.
