People imagine that since G‑d is not physical, therefore He must be in heaven. But the heavens—and all things spiritual—are just as much creations as the earth. Less dissonant, more harmonious, more lucid—but finite realms nonetheless.
G‑d is not found in a place because it is big enough to contain Him or so magnificent that He belongs there. G‑d is found in whatever place He desires. And where does He desire most to be found? In the work of our hands, repairing His world.
The heavens are filled with spiritual light. In the work of our hands dwells G‑d Himself, the Source of All Light.
