Over at From Wine To Water, Ivan takes another stab at addressing the problem of evil. His main argument, simply stated, is this: the Bible doesn't depict God's love as anything like our love (in fact, it's alien and dangerous, it provokes fear) and therefore to say "how would a loving God allow [Auschwitz/cancer/the cancellation of Firefly] is to misunderstand the concept of love. I won't tackle the hermeneutic question of whether the Bible does depict God's love as sufficiently alien - that would be a pretty mammoth effort - but I will give another objection to Ivan's argument.
In his post, Ivan asks "What job are you expecting God to do? And how do you justify that expectation?" The implication here seems to be that there's no biblical justification for expecting God to make everything happy and easy. But I contend that there's a clear moral justification! In the words of the great philosopher Parker, power is directly proportional to responsibility. The more you can do, the more you ought to do. If, like God, you can do almost anything, you've got a near-infinite obligation to act all the time to help people. Imagine you gained the powers, not of God, but of Superman - you'd have to help out with natural disasters and suchlike, at the very least. How much more, then, ought God to do?
The only way out from this argument that I can see is to propose that God is already acting to help people, and since He's omnipotent you shouldn't second-guess Him. This is the position ridiculed by Voltaire in the character of Pangloss, and it's not a very good one.
Of course, it doesn't follow from this that there's no God - simply that if there is a God, he doesn't conform to our standards of morality. In Ivan's words, "there is not some God who acts toward you exactly like your loving Dad did, or exactly like you think a loving Dad should."  But this presents a huge problem for believers. If your God is infinitely loving and kind in a way that I can comprehend, however dimly, then I've got a reason for believing in the face of huge odds. If your God, on the other hand, is 'loving' in the sense that somebody who is born paraplegic is loved, then my reason vanishes. I don't want to be in God's love for eternity if it's the same kind of love He showed the Auschwitz dead. You can bite the bullet, like Ivan, and dismiss the problem of evil - but in doing so, you dismiss the main intuitive attraction of Christianity.
 The word 'exactly' there bugs the hell out of me, by the way. Would you tell a victim of child abuse that they haven't been treated 'exactly like you think a loving Dad should'? No, of course not. That word trivialises the very real, very horrific reasons that many people have to doubt the concept of a loving God.
