I used to be a pre-tribber but I recently switched to a post-trib interpretation of the Scriptures. You see, the post-trib position is the only one that allows for the most smugness. If the Tribulation starts and the Elect haven't been raptured then I can point and say "I told you so!" If the rapture occurs pre-tribulation then the pre-tribbers will have neither the ability nor inclination to be smug. The defense rests.
