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.
