Now, any special action on God's part is often thought to present great difficulties, as interfering with the uniformity of nature. But, as we shall see, it would only interfere with it in the same way that human action interferes with it. Neither of them violates the laws of nature, though both are able to bring about results which nature of itself could not have brought about. In the case of human action this is quite obvious. Suppose, for example, a clock with an iron pendulum is placed on a table and keeps perfect time. Suddenly, without anyone touching it, it begins to gain rapidly, and then, after a short time, goes on as before. To anyone unacquainted with the cause, this would appear a _marvel_: and might even be thought incredible, as (assuming the clock to be properly constructed) it would seem to imply some alteration in the laws of motion, or the force of gravity. Yet we know a man can easily produce such a marvel by holding a magnet under the table. The disturbing cause, it will be noticed, was not really the magnet, which always acts according to law; nor the hand which held it; but the action of the _human will_ on matter. This took place in the man's brain, and enabled him to move first his hand, and then the magnet. Thus we may say the marvel was produced by _natural means supernaturally applied_; for the magnet was undoubtedly a natural means, yet nature of itself would never have used it in the way described. It required something _above_ nature (something _super_-natural) and this was the free will of man. Now, miracles claim to have been produced in a somewhat similar, though to us unknown, manner by the action of God's Will on matter, that is to say, by natural means supernaturally applied; and, if so, they are certainly credible, under this head. For we know that God has the power of acting on matter, and that He used it once in creating the universe, so He might use it again if He thought fit. Moreover, God's knowledge of the laws of nature is complete, while man's is only partial. As, then, man, with his limited power over nature and partial knowledge of its laws, can produce marvels so unlike nature's ordinary course (a steam engine, for instance), yet without violating any of its laws; still more can God, Who has complete power over nature, and complete knowledge of its laws. For to deny this would be to deny to God the power which we concede to man; and which we must remember, God Himself has given to man. And this would lead to the strange conclusion that God has enabled man to do what He cannot do Himself. No doubt we cannot imagine _how_ God can exert His Will over matter, but neither can we imagine how we can do it ourselves. The difficulty is as great in the one case as in the other.
