I've heard the 7 year cycle thing, too. But, lets face it, with so much bad news and twisted behavior at all levels of government across the globe, how do you pick this particular 7 year cycle? When did it start/end? Maybe they know something I don't, but I'm having a Hell of a time finding definitive beginning or end of the craziness since the last part of the Clinton years...
I'm certainly not one to ignore the evidence if someone has connected the dots to come to a conclusion worth acting on, but in the last 20 years or so, I think you could pick and choose your unfortunate tidbits from a huge well of crazy. And with everyone predicting the next global upheaval (granted, at some point one of them is going to be right) its hard to give credence to one doomsayer over another.
All of that being said, I do have a great deal of respect for the seriousness with which the Mormons take their prepwork. Its damned impressive!
