This is the first miracle which the Lord Jesus performed upon earth, thereby manifesting His glory unto His disciples, that they, as John distinctly relates, might thus learn to recognize Him as the Son of God and as the true Messiah; for He does here what no other human being can do: He changes that which is created, and makes wine from water. Such a deed can only be performed by God who is Lord over all creation; men cannot do it. This miracle chiefly serves to teach us who Christ the Lord is, so that with full confidence we may in time of need and trouble hasten to Him to 177seek from Him help and blessing, which we shall surely obtain at the proper time. This is the chief lesson of our Gospel today. But inasmuch as we derive this same truth and comfort from all the miracles of Christ, we will on this occasion dwell principally upon the fact that this miracle was done at a marriage; and we do this to the end that the doctrine concerning matrimony may be well known among Christians. This is a matter of great importance. (Luther’s House Postil, Sermon for the 2nd Sunday after Epiphany, Volume 1, p. 176-177)
