Their most famous type/anti-type is the "seven times" is Nebuchadnezzar's tree dream where his insanity for 7 years is compared to the gentile nations' 2520 years of rule until 1914.
This was one of those things where when I was a teenager who wanted badly to believe, the explanation in the Live Forever book made a lot of sense.
A year or two later I revisited that story in its proper context during a personal reading of the book of Daniel and for the life of me I couldn't understand how that dream applied to something other than the 7 years Nebuchadnezzar spent in madness. The bible was very clear about the dream and its application, but somehow we were supposed to take at face value that the tree represented god's kingdom, the chopping down of the tree the destruction of the second temple, the seven years seven times, blah, blah.
It's an incoherent mess and the only explanation they can offer up is "because we say so."
