Pretribulation Rapture - Is There a First Tribulation?

There is no easy way out, like, if you are faithful to god, or you will go to god before. Why do i find this debate interesting? Politically, it's not as stupid as you may expect. People point out that the those who think rapture, usually they talk about five, ten % people disappearing. But what interests me in this idea of left behind is, sorry, why is this theme so popular? I'm to offer a very vulgar materialist mark is but vulgar, but i think it hits apoint reading that, as usual, god is listening to economy.
