Prophecy is a complex subject often hard to understand. For that reason prophecy provides a playground for sensational speculation. In the 1970’s Hal Lindsay predicted Jesus would return one generation after Israel became a nation -1988. When that didn’t happen he amended his prediction. Since Israel did not have all the land until the 1967 War, Jesus would return in 2007. Obviously that didn’t happen. Now he says a generation is actually from 60-80 yrs. So Jesus will return in 2047.
