There has been considerable discussion at Five Doves about the Tribulation Period (7 years by Daniel 9:27) beginning back in October of 2008.  If that was so, then the Third Temple in Jerusalem by now should be present and complete in time for Mid-Tribulation in the spring of 2012.  For the antichrist, rising from a mortal wound, goes into the Temple in the middle of the 7 year Tribulation Period and claims to be God (II Thess. 2:4).  But there is just one problem!  THERE IS NO THIRD TEMPLE IN JERUSALEM RIGHT NOW!  Why?  Because the Tribulation Period has not yet begun, and will not begin until AFTER the Rapture.  Then the antichrist will come on the world stage and make the Daniel 9:27 covenant, beginning the 7 year Tribulation Period.  During the first half of the Tribulation the Third Temple will be built, which is yet in our future.  

Also, God's two witnesses (Rev. 11) will minister during the first half of the Tribulation Period in Jerusalem.  THEY ARE NOT PRESENT YET!  Why?  The Tribulation Period has not yet begun!

January 27th through 29th has passed without incident (sudden destruction / Rapture), and for those who still cling to the teaching that the spring of 2012 is Mid-Tribulation, in just a few months you will be proven wrong!

There is however, a strong possibility that the Rapture may happen sometime this year, as 2012 + 7 = 2019.  The Great Tribulation (last 3 1/2 years of the 7 year Tribulation) is shortened by one third (see Matt. 24:21 & 22 and Rev. 8:12), so by our present time standard 2019 would actually be 2018 since one third of 3 1/2 years is one year and two months.  2018 is precisely 70 years after 1948, the year Israel returned as a nation.  And remember, from the time Jesus was born until 70 AD when the Romans destroyed Jerusalem, took down the Second Temple stone by stone, and scattered the Jewish people to the nations, we also had a 70 year time period.
