Maybe God has given mankind the power of reason and knowledge but also the responsibility for whatever happens when we use it. Is man's inhumanity to man his/her fault or ours? Do you really want a life with no pain, no suffering, and no death? What would be the point of having the ability to reason and learn if we have no problems to solve?
Actually, that is no better than the parent analogy. That answer would be perfectly understandable, if our lives had difficulties, and challenges. It does. But, what? God decided my life wasn't challenging enough, so he decided my son needed to contract a fatal disease, and die, while I could do nothing? God decided that my life was not difficult enough, so, he sat back, and did nothing as a rapist violated my daughter? Really? And just what made me so special? Why were the normal difficulties, and challenges that life presents to...well...everyone, allowing them to grow, and develop their reason, and intellect simply not enough, that I required such special, particular attack from outside, that I did nothing to incur? And this is your benevolent God? Really?
You didn't answer my questions. Why?
