What happens to unbelievers at the Great White Throne after the thousand years?
After the thousand years, every unbeliever is brought before the Great White Throne to answer for what he did in the flesh. He sees the record and goes to his doom. Punishment has degrees: the seemingly good person suffers less than the vicious criminal.
Les teaches that the thousand years end, and then comes the time for everyone to answer for what they have done in the flesh. The Great White Throne is specifically for unbelievers; believers have already been judged or rewarded shortly after the Rapture. At this throne every lost individual is brought to see the record and then goes to his doom. Les also notes that there will be degrees of punishment: a person who lived a good life and thought he was doing all right will not suffer as much as the vicious criminal. Jesus illustrated this in His earthly ministry when He told Capernaum it would be more tolerable for Sodom and Gomorrah in the judgment day, because if Sodom and Gomorrah had witnessed the miracles Capernaum saw, they would have repented in sackcloth and ashes.
