G-d's plan for man: 

Creating a center and focal point for Israel and all mankind to gather together in profound and joyful nearness to G-d.

Raising up the world via the reality of the Holy Temple.

The Ark of the Covenant which contains the Torah, G-d's message to man, and the two golden cherubim point the way back to the Garden of Eden and the Tree of Life.

This is the place where G-d wants us to be.
