The evidence sure does seem like the events this September looks like the “great sign” in Revelation 12. But as far as I can tell, it doesn’t make any prediction about that date, but it does indicate it is a sign that Christ is coming soon. I am hopeful that Christ will call his church home soon.
I have had a tendency to look for the return of Yeshua during the Feast of Tabernacles each year, and this year have focus on October 5, 2017 as a possible return date.
