Those who around after the rapture on the earth are lost people. How sad.

After the rapture takes place the next thing on the prophetic calendar of the Living God will be the tribulation, God's judgment on the lost, who were left behind. They are the ones decieved by the anti-Christ. They will be the ones who will worship the beast, and the false prophet. Some of them will die when an earthquake takes place as part of the tribulation. Others will die when fire and brimestone from heaven hits them. Still the people will continue to worship the false leaders instead of God.
They will probably still believe in such myths as purgatory even then, among other lies.
