There are many, many of God's true saints in the land today who have been deceived by the teaching of the Millenium. The Millenium theory is a 2nd chance theory that originated around 90 A.D. with a wicked man named Cerinthus. Many Protestant groups have grabbed hold of this doctrine even as the Catholics have grabbed hold of the doctrine of Purgatory as a 2nd chance after death. But the Bible says in Hebrews 9:27 " For it is appointed unto man once to die and after this the judgement." Also, in Revelation 22:11 "He that is unjust let him be unjust still: and he which is filthy let him be filthy still: and he that is righteous, let him be righteous still: and he that is holy, let him be holy still." There is an old adage that says: "As a tree falls so shall it lie, as a man lives so shall he die, as a man dies so shall he be, forever the same throughout eternity."
