Which God are you? and why did you go to such lengths to conceal yourself?
I think for myself the answer to that would be a part of all of the gods. Personally I view god as all the gods, not to say every faith is true. But all are true and all are false. People experience life in various ways and a spirit will interact with people in different ways and be interpreted in different ways.
I would say the moment you try to define God, you've limited god and what this god is by the very definition. To have the best explanation I would draw from Kabbalist literature and say God in No Thing. God is not Any Thing.
So, why did he conceal himself?
Firstly, you were not looking in the right place. If God is No Thing ...then you can't find God in the tangibles, you find God in the intangibles.
That is to say the spiritual and the natural are different things. One is No Thing and the other is Any Thing.
We also find that nature "hides" itself as well, so it should be no surprise that God does.
We find that the uncertainty principle guarantees electrons will be partly unseen from us.
Are we really experiencing all the energy of reality? Or just part of it and what is the other part?
