Of vast importance is it that we should note precisely the point touched by the finger of miraculous evidence. It may be said, not only are miracles incapable of enforcing a train of argument, but they are incapable of establishing any moral or religious proposition. No physical demonstration, it may be alleged, can ever link itself on to a spiritual truth, because the two things belong to totally different spheres. We should get involved in metaphysical subtleties, were I to inquire thoroughly into this position. It is enough to say, that, admitting it, the exact point touched by miraculous evidence, is, according to the teaching of Scripture itself, the _office_ sustained and the _commission_ borne by a person. "The works which the Father hath given me to finish, the same works that I do, bear witness of _me_." "Jesus of Nazareth, a man approved of God among you, by miracles, and wonders, and signs, which God did by _Him_." In these passages, the witness of miracles is attached to a person. "My works bear witness of _me_," says Jesus. They are the approval of "_a man_," says Peter. The evidential force of them bears on Christ Himself, the sent of God. Thus considered, miracles free themselves from objections made to their competency to serve as direct proofs of spiritual truths. The miracles of Moses afford evidence of his Divine legation: in like manner the miracles of Jesus afford evidence of His Divine Messiahship. It is said of Him that "He taught them as one having authority, and not as the scribes." Authoritativeness is characteristic of His mode of teaching. "Verily, verily, I say unto you." He claimed a right to speak, as one who had power to command men that they should obey. There is in His utterance little of argument, but much of law. Miracles can add no force to a chain of reasoning, and you may say they cannot immediately demonstrate spiritual truth, but they afford a basis for the enunciation of a Divine message, a mandate of the Divine will. Miracles, no doubt, come within relations to spiritual truth, through the medium of the miraculously demonstrated authority of its utterer; but spiritual truth has other distinct and appropriate marks of its Divine origin and character. It contains an inward witness--it shines by its own light. It commends itself to men's consciences in the sight of God, and when believed, vindicates the justness and wisdom of such belief.
