The idea is, there are two total eclipses exactly seven years apart (the “Tribulation” period) and the path of both eclipses cross on the San Andreas fault in the States.
That, coupled with natural disasters and worldwide political upheaval, so much of it involving the Middle East and the U.S. siding with so many of our enemies (Iran in the previous administration—who was anti-Israel, and Iran’s support of North Korea.
I don’t particularly ascribe to the view that these are the seven years of the Tribulation but I can certainly understand why so many people hope or wish that they are. If you really want to know what those who ascribe to this view are thinking, watch TBN or Daystar or some Christian cable network. They may be wrong, they may be deluded, but they aren’t stupid. You can at least come to an understanding to the theology, numbers, and world occurrences behind this viewpoint.
I do not ascribe to this point of view. When the end-times or Tribulation arrive, you will definitely know it and I don’t think you’ll be mocking. You’ll be hiding in the rocks.
