Many Christians that do no believe in the rapture believe completely different things about heaven and hell than the Christians that do believe. And I think they also have different beliefs of who wrote Revelations. I may be wrong, but I seem to remember being told who wrote it (again, may just be the belief of that preacher??) And of course any of it is possible. We just really do not know for sure.
As for everyone saying this is about fear--well, actually, Christians who are believers of the rapture are not afraid at all. It would be welcoming. BUT, most of us don't go around thinking its coming tomorrow or trying to asign a date.
I actually thought the rapture was the first thing that is supposed to happen when the end is near, I guess I am confusing Left Behind with Revelations. Need to go back and read!
Anyone that doesn't know what the rapture is, read Left Behind. Remember it IS fiction, but it can give a general explanation of it. There are really good books. (and a lot easier to understand that Revelations

)
