It might be a part of it..I heard about the fault line and the water in 1972 from an old Billy Graham World Wide Pictures film about Israel and from other End times books at the time. Southern Baptists have been way ahead of the curve...end times speaking! They were predicting Israel’s re-emergence way before it ever happened.(So were various adherents of the Darbyists and out shoot followers)
So you might rethink the Darbyist views about the rapture!
