What will the millennial Kingdom be like and what will people need to prove?
The millennial Kingdom will be a thousand years of perfect environment, with no sin, no sickness, and no pain. During that time, people must demonstrate that their old Adamic nature can make a choice, proving their free will allegiance when Satan is released to test them.
Les explains that the Kingdom economy will be like Eden: for a thousand years people will have a perfect environment with no sin, no sickness, and no pain. Yet they will still have to show that the old Adamic nature has been able to make a choice. Just as Adam and Eve had to choose between following the adversary or remaining true to God, Satan has to be released so that the millennial people can demonstrate their choice.
