But all this experience would serve to convince them that the Father was in Him. He had, He says, lived among them as the representative of the Father, uttering His will, doing His works. These works might have convinced them even if they were not spiritual enough to perceive that His words were Divine utterances. But a time was coming when a satisfying conviction of the truth that God had been present with them in the presence of Jesus would be wrought in them. When, after His departure, they found _themselves_ doing the works of God, greater works than Jesus had done, when they found that the Spirit of truth dwelt in them, imparting to them the very mind and life of Christ Himself, then they should be certified of the truth that Jesus now declared, that the Father was in Him and He in the Father. "At that day ye shall know that I am in My Father, and you in Me, and I in you." What their understanding could not at present quite grasp, the course of events and their own spiritual experience would make plain to them. When in the prosecution of Christ's instructions they strove to fulfil His commands and carry out His will upon earth, they would find themselves countenanced and supported by powers unseen, would find their life sustained by the life of Christ.
Jesus, then, speaks here of three grades of conviction regarding His claim to be God's representative: three kinds of evidence--a lower, a higher, and the highest. There is the evidence of His miracles, the evidence of His words or His own testimony, and the evidence of the new spiritual life He would maintain in His followers.
Miracles are not the highest evidence, but they are evidence. One miracle might not be convincing evidence. Many miracles of the same kind, such as a number of cures of nervous complaints, or several successful treatments of blind persons, might only indicate superior knowledge of morbid conditions and of remedies. A physician in advance of his age might accomplish wonders. Or had all the miracles of Jesus been such as the multiplication of the loaves and fishes, it might, with a shade of plausibility, have been urged that this was legerdemain. But what we see in Jesus is not power to perform an occasional wonder to make men stare or to win for Himself applause, but power as God's representative on earth to do whatever is needful for the manifestation of God's presence and for the fulfilment of God's will. It may surely at this time of day be taken for granted that Jesus was serious and true. The works are given Him by the Father to do: it is as an exhibition of God's power He performs them. They are therefore performed not in one form only, but in every needed form. He shows command over all nature, and gives evidence that spirit is superior to matter and rules it.
The miracles of Christ are also convincing because they are performed by a miraculous Person. That an ordinary man should seem to rule nature, or should exhibit wonders on no adequate occasion, must always seem unlikely, if not incredible. But that a Person notoriously exceptional, being what no other man has ever been, should do things that no other man has done, excites no incredulity. That Christ was supremely and absolutely holy no one doubts; but this itself is a miracle; and that this miraculous Person should act miraculously is not unlikely. Moreover, there was adequate occasion both for the miracle of Christ's person and the miracle of His life and separate acts. There was an end to be served so great as to justify this interruption of the course of things as managed by men. If miracles are possible, then they could never be more worthily introduced. If at any time it might seem appropriate and needful that the unseen, holy, and loving God should assert His power over all that touches us His children, so as to give us the consciousness of His presence and of His faithfulness, surely that time was precisely then when Christ came forth from the Father to reveal His holiness and His love, to show men that supreme power and supreme holiness and love reside together in God.
