“You can hear a miracle a long way after dark. Miracles are very like radio waves in this way. Not many people realize that the ordinary radio wave and the extraordinary miracle have much in common. Left to their own devices, radio waves would not be audible for much more than forty or fifty miles. They travel on perfectly straight paths from their broadcast source, and because the Earth is round, it does not take them long to part ways with the ground and head out to the stars.”
