Forgive me tanakh, but what you have said is not according to scripture. The scripture is clear in that, Jesus will literally return to the earth to end the age and establish his kingdom. He himself will be ruling from Jerusalem on the throne of David, in fulfillment of the prophecy. Regarding Christ's millennial kingdom, we have the following:
"While you were watching, a rock was cut out, but not by human hands. It struck the statue on its feet of iron and clay and smashed them. Then the iron, the clay, the bronze, the silver and the gold were all broken to pieces and became like chaff on a threshing floor in the summer. The wind swept them away without leaving a trace. But the rock that struck the statue became a huge mountain and filled the whole earth.
Nebuchadnezzar's statue = represents all human government
The Rock = The Lord Jesus
The Rock falling on the feet of the statue and blown away by the wind without leaving a trace = Jesus dismantling the governments of the world via the seals, trumpets and bowl judgments, the result being the end of all human government
The Rock becoming a huge mountain and filling the whole earth = Christ's millennial kingdom on earth
When Jesus said, "my kingdom is not of this earth" he meant at that time. For his appearing in the flesh the first time was not to rule the world, but to meet the righteous requirements of the law, fulfilling them and to pay the penalty for our sins by the shedding of his blood. After that He rose on the third day and then returned to the Father. When he returns to the earth to end the age, His kingdom will be of this world during that thousand years. After that will be the new heaven, new earth and the new Jerusalem.
