Argument from morality as a compelling Christian argument: moral facts (e.g., torturing children for fun is wrong) require a grounding explanation

Cameron observes that just as the problem of evil grips people emotionally on the atheist side, the argument from morality grips people on the Christian side. The fact that "torturing infants for fun is wrong" seems objectively true — yet naturalism struggles to explain the ontological grounding of such moral facts. Cameron personally is on the fence about the standard moral argument but finds it interesting.
