In the Holy Zohar on Pinchas is says
“The lord buildeth Jerusalem”(Psalms)
He and no other. It is for this building that we are waiting, not a human structure which cannot endure. The Holy One , GOD, will send down to us the first house and the second house together, the first in concealment and the second openly. The second will be revealed to show all the world the handiwork of the Holy One, Baruch HaSem, in perfect joy and gladness. The first which will be concealed, will ascend high over that which is revealed, and all the world will see the clouds of glory surrounding the one which is revealed and enveloping the first one which ascends to the height of the glorious heavens. It is for that building that we are waiting. Even the future city of Jerusalem will not be the work of human hands, all the more so the Temple, GOD’s habitation.” Zohar III221a
BUT DO NOT BE MISTAKEN WE MUST DO OUR PART
Nachemya”h and Ezra offered Sacrifices on the the Temple mount even before a Temple was built ! In another place the Zohar says the Temple will be built before the exiles are gathered. So that the Shechinah first returns to the “mikdosh.” But if we are then only returning from exile the cloud of glory will be seen on the wise, great and Chassidim. All depend on what we do.
