Expositor's Bible Commentary Commentary John 2:11

"This beginning of his signs did Jesus in Cana of Galilee, and manifested his glory; and his disciples believed on him." — John 2:11 (ASV)

The purpose of Jesus’ first miracle after entering Galilee is not stated, but the nature of the miracle is very plain. Jesus had come to bring about conversion: water to wine, sinners to saints. And this latter miracle of transformation occurs in almost complete obscurity. Few know when or how it happens, but they know that it does happen.

The effect of this miracle is noteworthy. It marked the beginning of a ministry accompanied by supernatural power; and it proved so convincing to the new disciples that they “put their faith in him.” That is, the deed helped confirm the conclusion they had drawn from their previous interviews with him: Jesus must be the Messiah.
