The significance of this incident is manifold. First, it gives us the key to the miracles of our Lord. It has become the fashion to depreciate miracles, and it is often thought that they hamper the gospel and obscure the true claim of Christ. It is often felt that so far from the miracles verifying Christ's claim to be the Son of God, they are the greatest obstacle to His acceptance. This is, however, to misunderstand their significance. The miracles unquestionably formed a most important element in Christ's life; and, if so, they must have served an important purpose; and to wish them away just because they are so important and make so large a demand upon faith seems to me preposterous. To wish them away precisely because they alter the very essence of the religion of Christ, and give it that very power which through all past ages it has exerted, seems unreasonable.
When the Jews discussed His claims among themselves or with Him, the power to work miracles was always taken into account as weighing heavily in His favour. He Himself distinctly stated that the crowning condemnation of those who rejected His claims arose from the circumstance that He had done among them the works which none other man had done. He challenges them to deny that it was by the finger of God that He wrought these works. After His withdrawal from earth the miracle of the Resurrection was still appealed to as the convincing proof that He was all He had given Himself out for. There can be no doubt, therefore, that the power of working miracles was one great evidence of the Divine mission of Christ.
But though this is so, we are not on that account warranted in saying that the only purpose for which He wrought miracles was to win men's belief in His mission. On the contrary, we are told that it was one of His temptations, a temptation constantly resisted by Him, to use His power for this object without any other motive. It was the reproach He cast upon the people that except they saw signs and wonders they would not believe. He would never work a miracle merely for the sake of manifesting His glory. Whenever the unsympathetic, ignorant crowd clamoured for a sign; whenever with ill-concealed dislike they cried, "How long dost Thou make us to doubt? Show us a sign from heaven, that we may believe," He was silent. To create a mere compulsory consent in minds which had no sympathy with Him was never a sufficient motive. Was there a sick child tossing in fever, was there a blind beggar by the roadside, was there a hungry crowd, was there even the joy of a feast interrupted: in these He could find a worthy occasion for a miracle; but never did He work a miracle merely for the sake of removing the doubts of reluctant men. Where there was not even the beginning of faith miracles were useless. He could not work miracles in some places because of their unbelief.
What then was the motive of Christ's miracles? He was, as these first disciples owned Him, the King of God's kingdom among men: He was the ideal Man, the new Adam, the true Source of human goodness, health, and power. He came to do us good, and the Spirit of God filled His human nature to its utmost capacity, that it might do all that man can do. Having these powers, He could not but use them for men. Having power to heal, He could not but heal, irrespective of the result which the miracle might have on the faith of those who saw it; nay, He could not but heal, though He straitly charged the healed person to let no man know what had been done. His miracles were His kingly acts, by which He suggested what man's true life in God's kingdom should be and will be. They were the utterance of what was in Him, the manifestation of His glory, the glory of One who came to utter the Father's heart to His strayed children. They expressed good-will to men; and to the spiritual eye of a John they became "signs" of spiritual wonders, symbols and pledges of those greater works and eternal blessings which Jesus came to bestow. The miracles revealed the Divine compassion, the grace and helpfulness that were in Christ, and led men to trust Him for all their needs.
