 Start by saying, that's a really great question. I understand why you might ask that if you've experienced suffering yourself. Talk about that. Talk about how that caused you to wrestle and think about things because you've made a connection straight away. So sympathize. Second thing, look for the hidden assumptions. So if someone says, if there's a good God, why is there suffering in the world? There's an assumption there, and the assumption is that suffering or evil or injustice are wrong.
