The only problem with a finite mind and the concept of omnipotence is that I can't think of all the different ways God could have done things, I can only think of some. I'm not saying that the other ways I can think of are better since I don't know what the purpose is that God wants to accomplish by being, at least initially, distant from us and hard to reach.
So then you simply accept that he did things this way, and you don't know why, and don't care why? You don't know if there is a lesson to be learned, and you don't know what the purpose is, if any, for God wanting to be sought instead of readily available? It's okay to say you don't know.
How about a metaphor for our exchange?
I ask, "Why can't I cross the street anywhere I want?"
You answer, "Because it's the law and you'll die if you break it."
I ask, "Why did we make that law instead of designing some other system to get around on foot?"
And I'm waiting for a reply to that question.
