Finally the scientists took the lump into the laboratories, when behold! it melted as quickly as a lump of sugar melts in the mouth of a boy. They discovered that nature was no lump at all, but a bundle of beautiful, complex energies. Nature as _substance_ scientists have driven to the vanishing point; so much so that no great physicist would dare to say that there is any substance. Yet nature was never so potent in the lives of men as since it has been reduced to invisible energies. The knowledge of these invisible forces and the power to manipulate them make men almost like gods in their achievements. The present situation, then, is a little like that of putting the tunnel under the Hudson. One gang beginning on the Jersey side, and another on the New York side, they bored down and onward, sometimes going far below the water; but when the workers came together under the Hudson, they had varied from each other only by the least fraction of an inch. Just so the philosophers and theologians began on the spirit side, reducing spirit to purposeful energy; while the scientists began on the nature side reducing it to purposeful energy; and when the two sets of workers broke through, they were apparently at the same point. The Christian scholar looked up with joy and amazement, saying, "Why, this invisible, purposeful energy of nature is simply what God is thinking, and feeling, and willing. Whether there is any _substance_ we do not know, but whether there is, or is not, _nature is Will in action_. God continually purposes all these energies and they go forth. Light-energy, and all other beautiful forces constituting nature, are the modes of God's continuous will."
