Last month I responded to the question of why bad things happen to us. You continue the question of why with an interesting focus on the intentions of the Creator, rather than the experience of the creatures.
Theology is the work of trying to find rational answers to questions about ultimate reality.
That reality is always more than rationality can describe. Still, I can hear my theology professor, Dr. John Cobb, insisting that that there is a need to pursue the questions with all of one's mind. I submit that the answer you are seeking has at least as much to do with your heart and soul as your mind. You don't write about the life situation out of which your question comes. I'm assuming that it comes from the same deep place of despairing and aspiring from which the question comes to me.
