"I have a very basic philosophical response, and I’ve written on this many other ways. It runs something like this: the philosophical problem is actually far more intense than the skeptic actually thinks it is. The philosophical problem, or the problem of pain, is actually more complex and complicated than the philosopher actually thinks it is when he or she raises the question. . . .
"They raise the question of evil, and I’m telling you, it is more complex than they think it is. Why? Because one must question the questioner. If there’s such a thing as evil, you assume there’s such a thing as good. If you assume there’s such a thing as good, you assume there’s such a thing as a moral law on the basis of which to differentiate between good and evil. If you assume there’s such a thing as a moral law, you must posit a moral law giver, but that’s whom they are trying to disprove and not prove. Because if there’s not a moral law giver, there’s no moral law. If there’s no moral law, there’s no good. If there’s no good, there’s no evil. What is their question?
"Now you may question the last jump: why do you actually need a moral law giver if you have a moral law? The answer is because the questioner and the issue he or she questions always involve the essential value of a person. That is, you can never talk of morality in abstraction. Persons are implicit to the question and the object of the question. In a nutshell, positing a moral law without a moral law giver would be equivalent to raising the question of evil without a questioner. So you cannot have a moral law unless the moral law itself is intrinsically woven into personhood, which means it demands an intrinsically worthy person if the moral law itself is valued. And that person can only be God.
