But to such power there must be a limit. There are certain results which plainly lie beyond the power of any mere combination of the forces of nature to produce. Of these, many of the miracles recorded in the Gospels are instances, such as the cure of blind or leprous men by no other visible instrumentality than a word or a touch. Actions of this kind differ wholly in character from those which we are now considering. If a miracle was a more objective fact taking place in external nature, and nothing more, it might be open to question whether its performance was owing to supernatural agency, or to some combination of known or unknown forces. But the miracles with which we are concerned in this controversy, involve a great deal more than more objective facts in material nature. But assuming, as I cannot help doing in an argument like the present, the existence of a God, who is the Creator and Governor of the universe, the question is not a mere abstract one, what a Being like Satan, if he is supposed to exist, might be capable of doing; but it becomes entirely one of permitted agency. It is plain, that if there is a God, every being in the universe, however powerful or intelligent, can only act within a certain definite sphere of operation, which the Governor of the universe has assigned to him. Within what limits then is he allowed act? Are subordinate agents permitted to interfere with the material forces of external nature? and if so, within what bounds? Can they wander over the universe at their mere will and pleasure, and interfere with its operations? How far is their interference permitted in the moral and spiritual worlds? The question before as is even reduced to one of far narrower limits. Our only direct knowledge of the existence of such an agency is derived from Revelation. The real point therefore which concerns us is, to what extent is such permitted agency affirmed in the New Testament. Do the Satanic interventions there described interfere with divine miracles as attestations of a divine commission? We have nothing whatever to do with abstract propositions or with what Rabbinical writers may have affirmed on this subject, but with the assertions of the New Testament alone.
