Often you hear Christians gasp with amazement when they hear about the peculiar doctrines of cults like the Mormons and JWs. They often exclaim "How can anybody believe that?"
Typically, they have not read enough of the cults material too understand the reasoning behind some of these false doctrines. Hence, when they actually meet real live cult followers, they are confounded and have no idea how to answer them.
These false doctrines have not been plucked from the air. They are supported by twisted readings of scriptural passages. They are invariably based on wrong methods of eisegesis. Yet the reasoning behind them makes sense. When they present their arguments, you can see where they are going.
Yet despite the smart arguments, you are still left with the thought in your head "How can anybody come to that conclusion?"
For all the great theology that has come from Dispensationalist theologians, my thoughts on the Pre-Trib rapture are still exactly the same as my reaction to the odd doctrines of the cults- "How can anybody come to that conclusion?"
I have read book after book by Pre-Trib theologians. Yet I am still baffled as to how people come to think that there is a pre-trib rapture. The more arguments that Pre-Tribbers raise, the more implausible there proposition seems to me.
