It's a scam. They tell people that they need to go to find out what they need to do to survive the end of the system of things. Then, they get them in, where they are told that they need to go to all the boasting sessions, go out in field circus, and cut off all worldly ties. So they do those things, believing that it's what is necessary to survive. They end up becoming witlesses, and another 50 or more years come and go without the end coming. Of course, leaving at such point will put hardship and hassle in their way because the witlesses will hound them to death. They have even been known to use remaining family members, at the very least getting them to shun the departing witless, after hounding people to bring in their whole families.
The end is coming, regardless of what anyone tells--but being in a cult is not going to help you survive. And it is impossible to calculate the date--it will come from tyrants trying to control the whole world. Codex Alimentarius, the One World Totalitarian Government, and President Osama Obama are all working toward this. And, the Washtowel Slaveholdery itself would like nothing more than to seize control of the whole world and start the Second Dark Ages. People are going to die, and survivors will be enslaved and made stagnant to death. There is no cult that will give people escape once this happens.
