What will Satan be able to do after he is released at the end of the thousand years?
After the thousand years, Satan will be released for a little season and given full freedom to deceive the nations that will be back on the scene. He will have opportunity to test the new generations in that kingdom economy, making the millennium a seventh period of testing the human race.
Les explains that Satan is confined to the bottomless pit for the thousand years because he is not yet ready for eternity and still has one more opportunity. Once the thousand years are fulfilled, Satan must be loosed for a little season. At that time he will have full freedom to deceive the nations that will be back on the scene. He will again have the opportunity to test the new generations that come on the scene in that kingdom economy, so the millennium becomes another period of testing. Les notes this is the seventh period of testing, since God always does things in seven.
