“A prophet has no honor in his native place.” It's one of the few passages common to all four Gospels, but John brings it to a very different conclusion than the others. The lesson is not that Jesus could work few miracles because of their lack of faith. Far from it: it is in Cana of Galilee that Christ first reveals His glory and the disciples – Israel – come to believe in Him. It is in Cana again that the nations, in the person of the royal official, come to believe. “Lo, I am about to create new heavens and a new earth; the things of the past shall not be remembered or come to mind.” We've had this promise from the beginning, it's been with us in seed form since the first pages of Scripture; now God begins to give signs of its fulfillment.
Just as the sign at Cana began His public ministry, so this sign is placed at the beginning of the road to the Cross; a series of Gospel passages from John that will see us through Holy Week. Jesus will face increasing conflict with the chief priests and the Pharisees; the crowds will now be supporting one side, now the other. We've passed the halfway point; the Father has come out to meet us; now it is time to focus anew as Lent begins to build to its conclusion.
