I think Nicholas Wolterstorff's answer was the most human.
You've not addressed the fact that the Bible itself acknowledges that God's actions may seem unjust, and that humans don't have satisfactory answers sometimes. Paul said bluntly:
"But who are you, a human being, to talk back to God?" (And the rest of Romans 9)
Paul didn't pretend to know the answer. He said humans don't have the right to question God on his actions.
The Bible writers were apparently not ignorant of the problem of evil, nor did they ignore it. Their conception of God often included the idea that his qualities are difficult to reconcile and that we don't have good answers to why God acts in certain ways.
