The common definition of a miracle, as a violation or a suspension of the laws of nature, is open to very grave objections. The question, as I have observed, at once arises, what is included under nature? It also assumes that we are acquainted with the mode in which miraculous agency must be exerted; which we are not. Other definitions which have been proposed take for granted positions which those who undertake to prove the credibility of miracles ought never to concede. The plain fact is, that we are simply ignorant of the mode in which God acts on material nature; and every definition must be faulty which assumes that we have that knowledge. To say that miracles must involve even a suspension of the laws of nature introduces a needless difficulty. No law or force of nature need be suspended in its action to render the occurrence of a supernatural event possible. All that is necessary is that forces should be introduced which are capable of overbalancing the action of opposing forces. It is extremely inaccurate to affirm that the force of gravitation must be suspended in order to render possible either walking on the water, or an ascent into the sky. It is equally unwise and unphilosophical to affirm that God cannot work a miracle by the use of intermediate agencies, _i.e._ by the partial employment of the forces of the material universe. It is true that in most of the miracles recorded in the New Testament we cannot affirm the use of such media, although we observe an economy in the use of divine power: _i.e._ no power is exerted beyond that which is necessary to produce the particular result in question. But in the Old Testament the use of such media is unquestionably affirmed. To lay down in our definition of a miracle a particular theory as to the mode in which it must be accomplished, involves the whole subject in needless difficulties. This question has been obscured by representing a miracle as performed by the intervention of a higher law, superseding the action of a lower one. This introduces the conception of force into the idea of law, and leads to confusion of thought. Laws, or the invariable sequences between phenomena, are neither forces nor powers. The counteraction of one force by another is an event of daily occurrence. All that is needful for the working of a miracle is the intervention of a force or mental energy which is capable of acting on matter, and of overbalancing those ordinary forces which would produce a contrary result.
