The problem is as old as Socrates’ Euthyphro. If….”good” must mean approximately the same thing when we apply it to God as what it means when we apply it to human beings, then the fact of suffering provides a clear empirical refutation of the existence of a being who is both omnipotent and perfectly good. If on the other hand, we are prepared to give up the idea that “Good” in reference to God means anything like what it means when we refer to humans as good, then the problem of evil can be sidestepped, but any hope of a rational defense of Christianity goes by the boards. - Victor Reppert.
