Good question Daniel! And you aren't overthinking it. Psalm 90 tells us that a generation can be 70 or 80 years. We are past the 70 mark as you noted and when you add 7 years for the Tribulation we are very near or even at the 80 year point. That is why my Tipping Point book is subtitled, "The End is Here". I don't set dates, but like like you I do the math and it is exciting to say the least!
Thanks, Jimmy! This may be amplified by the fact that December 13, 2020 was the exact mid-point to the 2 total solar eclipses that cross the USA: August 21, 2017, and, 7 years later, in April 8, 2024. The paths of these two eclipses cross in a region called “Little Egypt” (near the Illinois, Missouri, and Kentucky state border) and occur 7 years apart.
