What is the millennial kingdom?
The millennial kingdom is the last thousand years of human history on earth, a time when the curse is lifted and conditions revert to Eden, with Christ as King in perfect government, no sin because Satan is bound. Only believers enter it, including Tribulation survivors who believed the Gospel.
Les explains that the millennial kingdom is the last thousand years of human history on the planet, pretty much as we know it, except the curse will be lifted and everything will revert back as it was in the Garden of Eden. He describes it as a time of true glory, a perfect government with Christ the King, and no sin because Satan is locked up. It will be the utopia that all of human history has been looking forward to. Regarding who enters, Les teaches that no unbelievers will go into the Kingdom; only believers. This includes the remnant of Jews who fled Jerusalem at the midpoint, the few survivors from Isaiah chapter 24, and those who heard the Gospel from the 144,000 and became believers. Survivors who rejected the Gospel will be removed. Jesus depicted this in Matthew 25 when He separated the sheep from the goats, which were all Gentiles.
