There are some who believe the antichrist will be muslim instead of European and some who believe the rapture will take place at the end of the Tribulation, but regardless, people will be forced to be marked at the midpoint, or 3 1/2 years.
I personally believe the rapture will happen before the Tribulation begins.
You might want to checkout Prophecy Watchers also, they have a website & TV program.
Hal Lindsy is selling books and that is all. The Tribulation is a 1800 teaching and was never part of the first century church. Nice story but a load of B.S. on it’s best day.
