The rapture has happened already. May 22 2011 I recall. It began with a series of earthquakes and the dead rose up from the grave. And there was mass panic and society collapsed. Planes crashed as their pilots were taken to heaven. And the world as we know ended that fateful day.
Or maybe nothing happened and it was all the dreams of a demented sicko, Harold Camping.
SO the only thing real about the rapture is the misery Camping bought to all those gullible people who believed his prophetic diarrhea. Many gave up their jobs and sold their homes so they could devote their final days to preaching and warning that the world was about to end.
