I am no theologian, and do not have the answers to these questions, and one of the reasons I enjoy the animals on the farm so much is that they don't think about their pain, or question it, they accept it and endure it, true stoics. I have never heard a donkey or cow whine (although I guess dogs do). I told my friend this: pain, like joy, is a gift. It challenges us, tests, defines us, causes us to grow, empathize, and also, to appreciate its absence. If nothing else, it sharpens the experience of joy. The minute something happens to me that causes pain, I start wondering how I can respond to it, what I can learn from it, what it has taught me or shown me about myself. This doesn't make it hurt any less, but it puts it, for me, on a more manageable level. I don't know if there is a God, or if he causes me or anybody else to hurt, or if he could stop pain. I try to accept it and live beyond it. I think the animals have taught me that. The Problem of Pain is that it exists, and is ubiquitous. The Challenge of Pain is how we respond to it.
