The return will be followed immediately by the reception into heaven of the elect and the banishment of the unsaved to hell, which will also be populated by Satan and the demons. They will stay there forever. The Bible does NOT teach the extinction of the soul. During these events, the elect will receive new bodies, free of all defects. We do NOT know the substance of such bodies.
Many Believers make such a belief a test of orthodoxy and of salvation itself.
Most of them are also willing to cast aside brethren who do not subscribe to a literal millennium. Heaven and Hell Heaven and Hell are real places. Hell is a place of unimaginable terror and woe, a place removed from the Presence of God. Heaven is filled with joy and peace and is in the Presence of God. We do not know what heaven and hell are really like.
