Here’s a good website for study material from a lot of other pastors/preachers/teachers in regards to the Rapture...
Pre-Trib Research Center
http://www.pre-trib.org/
They have a conference every year in Dallas where papers are presented and/or different people talk on the issue.
They have a lot of archived material there, too...
That's a good website.
Why I believe in the Pre-Trib rapture
Clarence Larkin was one of the finest theologians of the last century. He wrote right around the time of World War One. People thought he was nuts because he stated that a regathering of Israel would take place in actual fashion.
Hal Lindsey discredited himself by making so many specific predictions in his early years. John Walvoord, Dwight Pentecost, Charles Ryrie, and M.R. Dehaan are some of the traditional scholars who believed in an immediate rapture.
