When God spoke out of heaven to our Lord, self-centered men who heard it explained it by natural causes: they said, “It thundered.” This habit of explaining the Voice by appeals to natural law is at the very root of modern science. In the living, breathing cosmos there is a mysterious Something, too wonderful, too awful for any mind to understand. The believing man does not claim to understand. He falls to his knees and whispers, “God.” The man of earth kneels also, but not to worship. He kneels to examine, to search, to find the cause and the how of things. Just now we happen to be living in a secular age. Our thought habits are those of the scientist, not those of the worshiper. We are more likely to explain than to adore. “It thundered,” we exclaim, and go our earthly way. But still the Voice sounds and searches. The order and life of the world depend upon that Voice, but men are mostly too busy or too stubborn to give attention.
