In response to his last question, I like Hans Küng’s way of putting it – that God ought to be thought of as “at least personal” rather than impersonal, but also as “more than personal” since God’s existence transcends the level of reality on which we experience personhood.
In other words, we need to find ways of emphasizing that, when we talk about God, we are talking about a reality greater than we are, and we cannot do so by merely saying either that God is something less than we are (impersonal) or something that we are (personal).
On the question of whether “God did it” should be used as an explanation for anything, it is noteworthy that we have no events within the universe which provide unambiguous evidence of some sort of miraculous divine action. We have stories about seas parting in the past, but we do not have a contemporary case of a sea parting and slaves being freed as a result that we can point to and say, “Here we have something that cannot be explained in terms of the natural world as we understand it.”
There is a lot of interesting food for thought in Dale’s post and so I hope that there will be some discussion there and also here. Another commenter in the aforementioned post recommended reading about “Ultimism” by J. L. Schellenberg, and so that also seems worth mentioning.
