Fulfillments of Bible prophecies in the past seventy years (including an uptick in 2009 and 2012) indicate an asteroid may hit Earth (ending civilization as we know it) either between 2017-2024 or in about 500 years.
This is intensive research I have been doing for over 30 years, and started publishing in 2011.
I do have a book on Amazon (advertised on this site) that is self-published but probably not the best resource because it needs to be updated. It focuses on the major fulfillments of prophecy that occurred in 2009 and 2012, but it was published in 2013 and does not include most of the work (including the timelines and charts) that I have completed in the past five years.
The best resource for information on this topic (as of 2018) is the playlist on my YouTube channel that is linked below as a video. Just click on the video title to open the playlist on YouTube or watch the whole playlist here.
It is not my intention to continue this research after the year 2025.
