It's a pity that Revelation has become so popular with the absolute crazies, because it's actually quite beautiful.
Am always tempted to randomly quote from it in order to scare people though.
I thought the reference to the rapture was supposed to come out of First Thessalonians, not Revelation, is that not correct? However, I am aware that those pushing the rapture are big on Revelation.
Well the event is just the church meeting Christ when he comes back. For a specifically PRE-TRIBULATION rapture I hear Rev 3:10 used a lot:
"Because you have kept the word of My perseverance, I also will keep you from the hour of testing, that hour which is about to come upon the whole world, to test those who dwell on the earth" (NASB)
I don't believe in a pre-tribulation rapture, but some make a better case for it than others. I personally think it undermines the plain/normal/literal hermeneutic that Dispensationalists aim for. There are also people that support the idea for less than entirely Biblical reasons as I'm sure you can imagine.
