"the word "rapture" is not in the bible but the teaching is."

The closest thing in the Bible to the contemporary concept of the rapture is the picture of Christians being caught up to meet Jesus in the air as he is coming down at his return. The rest of the Dispensationalist calendar is put together by picking odds and ends of Bible quotes which in contest refer to an assortment of things, and arranging them on a structure constructed totally independently from the Bible. Put of any the verses used to support the doctrince back into context, and they lose all relevance to the alleged rapture-tribulation-final return sequence of the "left behind" scenerio.

I suspect that if Dispensationalism hadn't been popularized by the notes in the Schofield Bible, Mary Margaret MacDonald and Darby would be largely forgotten, and Dispensationalists would be very rare or have totally faded away.
