MacArthur on Jesus’ first miracle

By attending a wedding and performing His first miracle there, Jesus sanctified both the institution of marriage and the ceremony itself. Marriage is the sacred union of a man and a woman whereby they become one in the sight of God. The ceremony is an essential element of that union, because in it the couple publicly vow to remain faithful to each other. Both the Old Testament (e.g., Gen. 29:20–23; Judg. 14:10; Ruth 4:10–13; Song of Sol. 3:11) and the New Testament (e.g., Matt. 22:2; 25:10; Luke 12:36; 14:8) view the public ceremony as a necessary part of marriage.
