This cause--the cause of causes--must, it is further obvious, be in possession of a power far beyond the comprehension of our reasons or imaginations. All other power is derived from its power. All the power which is distributed and distinguished in secondary causes must be combined and united in the first cause. Now, think what an enormous power there is displayed even in this world. In every half-ounce of coal there is stored up power enough, if properly used, to draw two tons a mile. How vast, then, the power which God has deposited in the coal-beds of the world alone! The inhabitants of this little island, by availing themselves of the natural forces which Providence has placed at their disposal, annually accomplish more work than could by any possibility be effected by the inhabitants of the whole earth, if they exerted merely the power which is in their own bodies, the power of human bones and muscles. And yet there can be little doubt that, even in this country, we make no use at all of many natural agents, and only a wasteful use of any of them. "Weigh the earth on which we dwell," says an astronomer; "count the millions of its inhabitants that have come and gone for the last six thousand years; unite their strength into one arm; and test its power in an effort to move the earth. It could not stir it a single foot in a thousand years; and yet, under the omnipotent hand of God, not a minute passes that it does not fly far more than a thousand miles." The earth, however, is but a mere atom in the universe. Through the vast abysses of space there are scattered countless systems, at enormous distances, yet all related; glorious galaxies of suns, planets, satellites, comets, all sweeping onwards in their appointed courses. How mighty the arm which impels and guides the whole! God can do all that, for He continually does it. How much more He could do than He does, we cannot know. The power of no true cause, of no free cause, is to be measured by what it does. It must be adequate to produce its actual effects, but it may be able to produce countless merely possible effects. It has power over its powers, and is not necessitated to do all that it is capable of doing. It is difficult, perhaps, to show that the universe is not infinite. It is obviously unreasonable and presumptuous to deny that the power of its Author may be infinite. And yet we find men who do so. For example, the late Mr John Stuart Mill, for no better reasons than that nature sometimes drowns men, and burns them, and that childbirth is a painful process, maintained that God could not possibly be infinite. I shall not say what I think of the shallowness and self-conceit displayed in such an argument. What it proves is not the finiteness of God, but the littleness of a human intellect. The mind of man never shows itself so small as when it tries to measure the attributes and limit the greatness of its Creator.
