Water into Wine?

The miracle of turning water into wine at the wedding in Cana of Galilee is the first of seven “sign” miracles that John chose to record in his Gospel. Also included are the healing of the royal official’s son (4:46–54), the healing of the paralytic at the Bethesda pool (5:1–17), the feeding of the 5,000 (6:1–14), the walking on water (6:16–21), the healing of the man born blind (9:1–41), and the raising of Lazarus (11:1–46). Signs, for John, answer the question, “Who is Jesus?” They do this in part by affirming one or more of the titles ascribed to Jesus in the prologue (1:1–18).

What is revealed about Jesus in this first sign?

Through Christ all things were created; he has power over the material universe. Who is Jesus? He is the Messiah who has come in the fullness of time, to usher in the longed-for messianic age—in which wine (evidence of blessed fruitfulness and provision) will flow in overwhelming abundance and the mountains will drip with the best wine for the joy of God’s people (Joel 3:18; Amos 9:13–14; Jer. 31:12).

Who is Jesus?

He is the One who takes what is meant for purification and provides blessing through it. In doing so, he shows that he transforms the daily Jewish purification rites by the power of his perfect life (cf. John 2:6–7 and Heb. 9:12; 10:10). Who is Jesus? He is not merely the guest at our weddings but the great eschatological bridegroom who makes us his bride, by the cost of his life (Eph. 5:22–33). He clothes us with the wedding garment of his own righteousness (Isa. 61:10) and prepares us for the great wedding banquet of the Lamb (Rev. 19:6–10).

Who is Jesus?

He is the Lord of glory, who calls us to believe in him and to put our trust in him.
