Revelation 20

Following the destruction of the beast and his followers, Satan is bound for 1,000 years while Jesus Christ reigns upon the earth.  After 1,000 years have passed, Satan is released and leads a short-lived rebellion against Christ.  At this point, all - living and dead - are judged.  All those not found in the Lamb's book of life are cast into a lake of fire to be eternally separated from the presence of God's blessing.
