The circumstances incident to the miraculous act are instructive to contemplate. The presence of Jesus at the marriage, and His contribution to the successful conduct of the feast, set the seal of His approval upon the matrimonial relationship and upon the propriety of social entertainment. He was neither a recluse nor an ascetic; He moved among men, eating and drinking, as a natural, normal Being.[337] On the occasion of the feast He recognized and heeded the demands of the liberal hospitality of the times, and provided accordingly. He, who but a few days before had revolted at the tempter's suggestion that He provide bread for His impoverished body, now used His power to supply a luxury for others. One effect of the miracle was to confirm the trust of those whose belief in Him as the Messiah was yet young and untried. "His disciples believed on him"; surely they had believed in some measure before, otherwise they would not have followed Him; but their belief was now strengthened and made to approach, if indeed it did not attain, the condition of abiding faith in their Lord. The comparative privacy attending the manifestation is impressive; the moral and spiritual effect was for the few, the inauguration of the Lord's ministry was not to be marked by public display. MIRACLES IN GENERAL The act of transmutation whereby water became wine was plainly a miracle, a phenomenon not susceptible of explanation, far less of demonstration, by what we consider the ordinary operation of natural law. This was the beginning of His miracles, or as expressed in the revized version of the New Testament, "his signs." In many scriptures miracles are called signs, as also wonders, powers, works, wonderful works, mighty works,[338] etc. The spiritual effect of miracles would be unattained were the witnesses not caused to inwardly wonder, marvel, ponder and inquire; mere surprize or amazement may be produced by deception and artful trickery. Any miraculous manifestation of divine power would be futile as a means of spiritual effect were it unimpressive. Moreover, every miracle is a sign of God's power; and signs in this sense have been demanded of prophets who professed to speak by divine authority, though such signs have not been given in all cases. The Baptist was credited with no miracle, though he was pronounced by the Christ as more than a prophet;[339] and the chronicles of some earlier prophets[340] are devoid of all mention of miracles. On the other hand, Moses, when commissioned to deliver Israel from Egypt, was made, to understand that the Egyptians would look for the testimony of miracles, and he was abundantly empowered therefore.[341]
