God created the possibility of evil; people actualized that potentiality. The source of evil is not God's power but mankind's freedom. Even an all-powerful God could not have created a world in which people had genuine freedom and yet there was no potentiality for sin, because our freedom includes the possibility of sin within its own meaning.
Peter KreeftThus moral theology leads us four steps deeper than law. To fulfill the moral law, we need love. To get love, we need union with God. To get union with God, we need the new birth. And to get the new birth, we need faith.
Peter KreeftThe closer we are to God, to divine attributes - such as absolute truth, goodness, and beauty - the more we wonder. When we separate ourselves from truth, goodness, and beauty, we lose wonder and become cynical. The Enlightenment was basically the narrowing of our vision to a purely scientific, empirical, rationalistic worldview, screwing down the manhole covers on us so we became squinting underground creatures.
