I don't necessarily agree with everything in these sites, but I recommend them for their scriptural presentation of the Post-Tribulation view. The time and nature of the "Rapture" may not be of paramount importance, but neither are they merely academic. Anyone who expects to be raptured before the Antichrist appears will be unlikely to recognize him when he does appear.
Bread on the Waters Ministry: William D. Brehm's interesting web site; William believes, as do an increasing number of Bible students, that Islam is the Beast of Revelation. He identifies (erroneously, in my opinion) the Tribulation and Wrath. But the site is provocative and useful. His message is the wholesome one of "Be Prepared."
The Seventh Trumpet Rapture: Articles and teaching by James Underwood and Mike Rouse which prove from Scripture that the Pre-Tribulation Rapture is a myth and offer convincing scriptural evidence for a Post-Tribulation and Pre-Wrath Rapture.
Ed Tarkowski's articles on The Second Coming and much more. Examines and refutes the Pre-Tribulation Rapture theory.
Unmasking the Pre-Trib Fallacies: An online book exposing the fallacious reasoning which has caused multitudes to mistakenly assume that there is a Biblical basis for the Pre-Trib Rapture. That doctrine may be the world's most egregious example of wishful thinking.
Corrie Ten Boom on the Rapture: Corrie Ten Boom comments on the Rapture theory that is popular today. She exhorts us to prepare ourselves spiritually for the coming trials of our faith. She tells how the Chinese Church was unprepared for the persecutions under Mao Tse Tung's Red Guard (beginning in 1949) because of the doctrine of the Pre-Tribulation Rapture they had been taught.
