"I may burn in hell for his flawed craftsmanship."
"I do not think that it would be easy for just any god to reveal himself, but I do think that it would be incredibly easy for the Christian god to do so. The problem is that Christians have usually insisted on an omnimax god. So it seems difficult to imagine insurmountable odds for such a being."
It is a fair concern. My response to that, as indicated in my thread with Pete about free will, is that expecting a God in the nature that I think him to be to do certain things are actually nonsense statements. Example, even many atheists acknowledge that asking an omnimax God to create a rock he can't lift is asking something nonsensical. Or, can God create a God that can kick his own a$$. Or, can God create a square triangle. Asking God to create free will (for example) but at the same time make it impossible for these 'free-will' endowed beings to choose against God or what not is in the same category of nonsensical requests.
"The tricky business is just in how to explain this god's strange inability to communicate. The FWD is the only defense that Christians seem capable of mounting in the face of such a conundrum,"
The FWD is only one aspect of the defense, depending on where the particular atheist is coming from. But the 'strange inability to communicate' goes to my epistemology points, not to free will.
"Uh, yeah. If you ignore the entire Old Testament, in which God intervened all the time in very direct ways."
Did he? I thought you were arguing for Divine Silence.
Your other questions are not without merit, but they seem to fly in the face of your premise in this thread. Although, its worth mentioning, you asked if God expected people to fail... I again point out that from the beginning of the OT to the end of the NT the race of man is deemed a fallen race. So yea, God expected people to fail. That too is the point of Christianity.
"Nonsense. From what we can tell, there is plenty of evidence that lots of Christians, if not the majority before the 4th century, believed that Christ was a mere mortal."
We could war that out historically. I seem to recall rareairpug chewing somebody up for making that argument. You are relying on secondary sources. If you go to the primary sources there are lots of examples to contradict this. Its not worth arguing about here. You are not arguing with Christians of the 2nd century. You are arguing with Christians in 2006.
To the extent that the point has any merit at all, it should be added that the Christian community itself was aware of all sorts of groups trying to take the Christian label but not really having Christian theology. As I pointed out to CNM, the NT says that that was coming. No one reading the epistles of Paul in 110AD should have been surprised to see it. The response was the establishment of a number of creeds laying out the orthodox POV 'for the record.'
"Gee, I don't know. If God created the entire universe, he might be up to handling the rather tiny human population, don't you think?"
Sure, but that doesn't mean pleasing all of them. You can't please them all, when they've got mutually exclusive requests.
You're so smart...

help God with this one....
Teams A and B are playing against each other in Sport X. Team A prays to God that Team A will win, Team B prays to God that Team B will win.
Now, how should an omnimax God respond? Can you think of a response that preserves the point of the competition in the first place?
"I can understand why the President doesn't want to meet people who are carrying guns. I don't think that God can be reasonably said to have the same concerns."
Sure, you can understand the easy example. But what about a harder example? It doesn't even have to be the President. It can be anyone who is in a position of authority who is tasked to take into account all of the facts and then make the final decision. The President is a good example because he has access to a wider pool of facts that you and I don't have access to. If he makes a decision that baffles you, it doesn't necessarily mean that he has made a bad decision- perhaps you'd have made the same decision if you had access to the same pool of facts. But you don't have access to all the facts. You don't even have a right to them.
We vaccinate our children. The shots hurt. What's it seem like from the perspective of the infant? It looks like we're sitting there letting the doctors hurt them a great deal. They don't have access to the same facts: they don't know that we are trying to save them from an even greater pain.
