”By contrast God is a natural stopping point as a foundation for objective moral values and duties. For unless we are moral nihilists, we have to recognize some stopping point, and God as the ultimate reality is the natural place to stop. Moreover, God is by definition worthy of worship, so that He must be the embodiment of perfect moral goodness. Again, God, by definition, is the greatest conceivable being, and a being that is the ground and source of goodness is greater than one that merely shares in goodness. So theism isn’t characterized by the sort of arbitrariness and implausibility that afflicts stubborn humanism.”[1]
