[S]ince we know beyond a reasonable doubt that God exists and that he has the characteristics we’ve listed above—characteristics that include design, purpose, justice, and love—then we should expect him to reveal more of himself and his purpose for our lives. This would require that he communicate with us.I Don't Have Enough Faith to Be an Atheist, p.200, Norman Geisler and Frank Turek
I have been running across a number of Christians in the blogosphere recently who justify their belief in the divine inspiration of the Bible, in part at least, on the grounds that it is reasonable to think that God would want to explain what's going on to us directly. I just can't see why this would be so. Certainly God might choose to communicate with us (and I would be interested to know what he had to say if he did), but why in the world should I think it more likely than not that he would want to?
If an infinite, omnipotent, and omniscient God exists, he is so far above us that I don't see how we could ever have any reasonable expectation that he would want to explain himself to us. We cannot have any expectation that we are even capable of understanding his purposes. There is no reason to think that we are anything more to him than an ant farm or a tank of tropical fish, i.e., something that he finds interesting to observe from time to time, but nothing with which he desires to communicate.
It seems to me to be every bit as reasonable to think that God expects us to figure out things for ourselves. He gave us the world to live in and the capacity to reason and he is watching to see what we come up with. It might be that communicating with us directly would defeat his purposes completely. I can't know this to be the case, but it is no less reasonable than thinking that communicating with us would achieve his purposes.
As far as I can tell, this idea that we should expect God to reveal himself to us is founded on nothing more than our capacity to reason, but that is like a dog thinking that he is the center of his owner's universe rather than her cat because his ability to respond to a few simple commands means that he is on her wavelength in some fundamental way that her cat is not. It could just as well be that she views them equally as mere pets, or even that she responds to her cat in some important ways that are beyond the dog's ability to comprehend.
The significance of this for the belief in divine revelation is that unless we have good reason to think that God would want to communicate with us directly, it is really hard to see any justification for wasting much time to trying to figure out whether he did.
