7. The problem of a “mixed population” during a literal earthly millennium.
A theological problem with the premillennial view is that it means that resurrected believers with glorified, newly created bodies would be living in the old creation with people with corruptible bodies, many of whom will become unbelievers at the end of the millennium. The response that the incorruptible Christ dwelled with people having corruptible bodies for forty days after His resurrection is interesting but not fully satisfying.
