With regard to the healing of diseased matter, conjectures also can only be offered, because of the source of diseases we know so little. Sight is restored in cataract by simple removal of an abnormal membrane. Many fevers, if the germ theory or the poison theory be correct, are cured when the germs die, or the poison is eliminated. A power that could kill the germs, or remove them or the poison from the system, would then effect immediate cure in accordance with natural laws. It does not seem necessarily beyond man's reach to effect this when he shall understand natural laws more fully; it cannot, therefore, be a breach of natural laws if God should effect it by laws as yet unknown to man, provided they are brought into play with no other agency than the motion of matter.

It would be folly as well as impiety to assert that it is in such ways only that miracles are performed. No such assertion is made. But when, on the other side, it is asserted that the miracles narrated in Scripture cannot be true because they must involve a breach of the immutable laws of Nature, the answer is justifiable and is sufficient, that they do not necessarily involve any breach of any law, save of that one law of inertia which at every instant is broken by created things, without any disturbances being introduced into the serene march of Nature's laws. The scientific revelation is reconciled with the written revelation when it is shown that neither necessarily implies the falsity of the other.

But supposing the argument thus far to be conceded, it will be urged that the real "miracle" remains yet behind. When man moves matter, his hand is visible: when an animal gnaws a tree, its teeth are seen working; when a river flows down a valley, its force is heard and felt. How different, it will be said, is God's working, where there is no arm of flesh, no sound of power, no sign of presence.

Unquestionably it is a deep marvel and a mystery, that impalpable spirit should act upon gross matter; but it is a mystery of humanity as well as of Godhead. What moves the hand? Contraction of the muscles. But what causes contraction of the muscles? The influence transmitted from the brain by the nerves. But what sends that influence? It is mind, which somewhere, somehow, moves animal tissues—tissues consisting of carbon, oxygen, hydrogen, nitrogen, phosphorus, and sulphur. At some point of our frames, we know not yet where, mind does act directly on matter. It is a law of Nature that it should so act there. But if God exists, His mind must, by the same law, act on matter somewhere. Can we call it an offence against law if it acts on matter elsewhere than in that mass of organized pulp which we call brains? If no possibility of communication between mind and matter could anywhere be found in Nature, we might call such communication contrary to natural law. In other words, if it were one of the properties of matter that it could not receive motion from that which is not matter, its motion without a material cause would be supernatural. But since it is of the very essence of existence that matter in certain combinations should be capable of being endowed with life, and by such endowment become capable of being affected in motion by mind, it is indisputable that such capability is one of matter's properties, and that its being so affected falls within and not without Nature's laws.

It may be objected that, since it is only living substance which can be acted on by the human mind, it is contrary to law that dead matter should be acted on by Divine mind. But this is a simple begging of the question at issue. It is constructing a law for the purpose of charging God with breaking it. Where do we find evidence in Nature that matter cannot be moved by the Divine mind? Science reveals no such law. Science is simply silent on the subject; it admits its utter ignorance, and declares the question beyond its scope. Undoubtedly it does not pronounce that God does move matter, but it equally abstains from asserting that God does not. For when it traces back material effects from cause to cause, it comes at last to something for which it has no explanation. When we say that an acid and an alkali combine by the law of affinity, that a stone falls by the law of gravity, we merely generalize facts under a name, we do not account for them. What causes affinity, what causes gravity? Suppose we say the one is polar electricity, the other is the impact of particles in vibration (both of which statements are unproved guesses), what do we gain? The next question is only, what causes electricity and what causes vibration? Suppose, again, we answer that both are modes of motion, we only come to the further question, what causes motion? And since motion is a breach of the law of inertia, what is it that first excited motion in this dead matter? Carry back our analysis as far as we will or can, at last we reach a point where matter must be acted upon by something that is not matter. This something is Mind; and God also is Mind.

Again, when any one affirms that only living matter can be acted on by mind, whether human or Divine, we may fairly ask him, not indeed what is life, which is a problem as yet beyond science; but how life changes matter, which is a question strictly within the range of science dealing with matter. But to this inquiry we shall get no answer. The cells in an organism, the protoplasm in the cells, are living when the organism is living, dead when the organism is dead, and, as matter, no difference is discoverable between them in the state of living and dead. The cells consist of cellulose, the protoplasm of some "protein" compounds; no element is added or subtracted, no compound is altered, when it lives or when it dies. Nor can science even tell us when an organic compound becomes alive, or dead. Every instant crude sap is becoming living plants, every instant crude chyle is becoming living blood, every instant living organisms die and are expelled from plants by the leaves, from animals by the lungs, the skin, and the kidneys. Yet no physician can say at what moment any of these carbon compounds become living, or when they cease to have life. Since of this perpetual birth and death in all nature we know absolutely nothing, it is manifestly unreasonable to lay down laws respecting them. If life and death make (as far as we can discover) absolutely no immediate physical change in the matter which they affect, how can we propound as a dogma of physical science that God cannot move "dead" matter, when our own experience tells us that our spirits can move "living" matter?

It is clear that if we are not warranted in making a law, we are not warranted in saying that it is broken. Our concern with laws is to see that such as we do know are uniform, for this is the basis of science. But true science repudiates dogmas on subjects of which it avows its ignorance.

Let us sum up the argument as it has now been stated. The propositions are the following:—

The bearing of these conclusions upon prayer, in so far as it affects physical conditions, may now be briefly shown. It has been argued that, in the light of modern discovery, prayer ought to be restricted to spiritual objects, and that at all events it can have none but spiritual effects. It has for example been asserted that to pray for fine weather, for bodily health, for removal of any plague, for averting of any corporeal danger is asking God to change the laws of Nature for our benefit, that this is what He never does, what would produce endless confusion if He should, and consequently what He certainly will not do.
