We can find an answer to the problem with which small and great grapple, namely, why doesn’t God reveal Himself?
What will God do in order to be revealed?
The difficulty is not because He conceals Himself, but because we are not capable of seeing Him.
The problem lies in the vessels, and our tools of comprehension, which are physical tools, are not at all on the level that enable us to comprehend Him.
“Man shall not see Me and live” (Ex. 33:20), not because there is concealment blocking man, but because there is man.
We cannot see because our reality consists of a world in which the basic perception of its physical nature conceals the existence of God.
Rabbi Adin Steinsaltz
