In the context of biblical revelation, we must add a third question: “Is the good good because the very essence of God is good?” The good is not a product of an arbitrary decision of a mere will sporting about in a vacuum. Neither is it good because God’s will happens to yield to an alleged higher set of (Platonic) principles to which the Creator of all is subservient. Rather, the good is good because it is consistent with God’s very nature. God’s self-determinations always express who he is. He cannot deny himself. God wills the good and holiness because he is good and holy. God is always displeased with evil and unholiness because in his very essence he is awesomely separate from all the evil and unholy.
