Book excerpt: What if God is as rational as our own existence? Sitting in a pub one Christmas Eve, two friends hash out their doubts and questions about God, the Trinity, and existence itself. They agree that the Christian Trinity does not make much sense, yet when they look at the origins of the universe, they realize it also does not make sense, and for exactly the same reasons. And if the enigma of the Trinity is the same one underlying the universe, then perhaps the Trinity is as rational to believe in as our own existence. Yet as the night goes on, they realize the same tact can be taken with lots of other mysteries as well, including free will, the soul, God, eternity, truth, and meaning. If such things were not real, then would we even exist to talk about it?
