What does John 2:6 mean?
Turning water into wine was the first of John's seven highlighted miracles—called "signs"—meant to prove Jesus' divinity. This miracle is not only a kind gift to the bride and groom. It is also a powerful metaphor for Jesus' role as Savior. The water jars were used for ritual purification, holding around twenty-five gallons, or nearly ninety-five liters, each. Six is the biblical number of man; it can also represent imperfection. Seven is the "perfect" number: the number of God. Wine is a common biblical symbol of blood.Jesus transformed water, meant for ritual cleansing, into wine, representing blood. In a symbolic way, this mirrors how Jesus' sacrifice transformed the rituals of the law into the gospel of grace.
According to John 2:11, this was the first miracle Jesus had ever performed. Later verses will explain that only the servants, Mary, and the disciples would have known about the event. True miracles are always a message from God, and this miracle is meant to teach the new disciples about Jesus.
