The Apostle John was given a vision and a glimpse into the future, specifically the end times.  [The site cites Revelation 11:2 in the NIV, see below]  He was told to measure the temple.  Today, this temple does not exist, but shortly it will. Today, Gentiles (any person who is not Jewish) have control of the Temple Mount. Two of the Arabs most holy sites, the Dome of the Rock and the Al Asqa mosque, are located on the original temple site and where the Jews will rebuild their sacred temple. I believe the Antichrist will forge a 7 year peace agreement that will allow Israel to rebuild her temple.

Revelation 11:1-2 (KJV):

¹ And there was given me a reed like unto a rod: and the angel stood, saying, Rise, and measure the temple of God, and the altar, and them that worship therein.

² But the court which is without the temple leave out, and measure it not; for it is given unto the Gentiles: and the holy city shall they tread under foot forty and two months.

These Jewish leaders are serious:  They want to rebuild the Temple in Jerusalem on its original site and then restore the old Leviticus era sacrifices.  Read this:

The timing of the gathering isn’t coincidental: This was the date on which the people of Israel were commanded to take a lamb and sacrifice it, before the exodus from Egypt. The ceremony on Thursday will be, in Israel Defense Forces (IDF) lingo, “practice with live fire.” Slaughtering lambs, sprinkling their blood on the altar by priests dressed in kosher priestly garments and roasting the lambs, with their heads, legs and innards. Just as God intended.

And this, describing two problems:

Everything is ready, then, except two additional, small matters. The easy one, you’d be surprised, is the Ark of the Covenant. “The Second Temple didn’t have an ark, either,” Segel reminds me, and Friedman adds, “There are 10 studies about the location of the Ark of the Covenant. We read them and studied all of them, and reached the conclusion that the right answer is that it’s buried in the tunnels under the Temple Mount. When the day comes, we will get to it.”

The more problematic issue is the Al-Aqsa Mosque, the Dome of the Rock, which slightly impedes the architectural plans. “The temple will not be built through private acts and blowing up mosques,” emphasizes Segal. “That’s not the direction. The direction is changing consciousness. The preparations are mental more than anything.” One of the people involved in preparations, who requested anonymity, explains, “If not for the problem of the Dome of the Rock, they would build the temple today, and the temple would be built there. The third temple will be built by the government of Israel, not by private individuals. No one will do what shouldn’t be done, like an underground action to blow up the Dome of the Rock. The people who are committed to establishing the temple are normative and rational people, and just like we established the State of Israel, the day will come when we will build the temple, in an orderly, state-sanctioned manner.”

Segel notes that it can all start small: “The location of the altar where sacrifices are allowed on the Temple Mount is not within the bounds of Al-Aqsa,” he says, “so at least they should let us sacrifice on the Temple Mount.” But before any sacrifices take place there, much may have to change: Currently, the State of Israel doesn’t often authorize Jews to ascend to the Temple Mount, much less pray there.
