One of the main reasons that I'm mormon is that I think that some questions are answered by the LDS theology that can't be answered in traditional theology.
Case it point:

and

I view these as fundimental to christian belief, and they simply aren't addressed coherently. I admit that I have to think about things a bit more but that is one reason why I'm intrigued by Ostler.
