Okay so lets say they can get it done in 1 yr.
Dan 9:27 ...But in the middle of the week He shall bring an end to sacrifice and offering.
The AC stops Temple practices 3 1/2 years into the Tribulation and I believe this is when the 2 witnesses are killed. That would mean the Temple is under construction 1 yr prior to the Tribulation. Also, prior to this is probably the 1st war of Gog and Magog and preceding that is probably the war noted in Psalm 83.
I do believe in a Pre-Trib Rapture, but I don't think it will occur much before the Tribulation. If I'm correct that means we will see several of these events occur.
As always I'm interested in your thoughts or those of anyone else who takes prophesy seriously.
As to the Temple being rebuilt- if the article I posted is correct, and the Tribulation is wrapped up in 2017, and we, like God, determine all of this by going according to the Jewish calendar, then midpoint to 2017 would be 2013. That means construction on the Temple would have to begin sometime this year. (This is also going according to the Jewish New Year, which begins in the fall. We are currently in the Jewish year 5770 which started on nightfall September 20, 2009. The Jewish year 5771, our 2010, will begin nightfall September 10, 2010. That date would start the countdown to the date on the Jewish calendar which would be our 2013).
That is what makes this particular prophecy very interesting.
All of this is speculation and remains to be seen whether or not it will happen. We certainly don't have long before we know for sure.
