Only every three years do we get to follow the traditional reading for the Second Sunday After Epiphany (this coming Sunday)!  As LSB 399 makes clear ("The Star Proclaims the King is Here") the traditional order is Epiphany--January 6 has the visit of the magi from Matthew 2 (verses 1-2 of the hymn), the following Sunday has the Baptism of Our Lord (verse 3), and the Sunday after that (this coming Sunday) has the Wedding at Cana from John chapter 2 (verse 4, verse 5 being a doxological stanza to the Holy Trinity).  In fact, the earliest celebrations had all three events rolled into one grand manifestation (epiphany) of Jesus' glory.

In the icon pictured above notice how Jesus stands next to the groom and Mary stands next to the bride.  All four of these people are part of the story.  At the wedding itself Jesus would have been the least important and unknown, but due to His activity and divine gift to the couple (and the creating of faith in His newly-called disciples) He reveals God's glory in this, the first of His "signs."  Jesus is the true Bridegroom, and we--the Church--are His bride.  In this icon Mary, the virgin mother of God, represents the basic reality of the Church--just as the birth of our Savior from a virgin is something only God can bring about, so also the existence of the Church and each individual believer is a divinely-wrought gift, brought about through the Word of our Lord (preached and sacramental).

Notice also the servants are four in number, probably emblematic of the four Gospel writers (though only John's Gospel has the story of the turning of water into wine at the wedding of Cana).  All four, though, record the multitude of ways in which Jesus revealed His divine glory throughout His ministry, and also the passionate love of our heavenly Bridegroom that caused Him to ascend the cross, taking our place there, in order to take what was ours and give us what was His, only to rise from the dead on the third day to confirm the Word of God:  "Your love, O God, is stronger than death."
