The home town crowd is astounded at Jesus’ teachings and deeds of power. Jesus is astounded that it doesn’t make a difference.To the town-folk he is still the simple carpenter, the son of Mary, even if he can cast out demons and heal the sick and speak with wisdom which defies explanation. To be fair Jesus is asking neighbors and relatives to suspend logic and move beyond anything they could imagine about him. That is the difference between knowing and believing. They can see that there is something different about him and even name it but they cannot (or will not) believe he is more than the Jesus they have always known. That is what happens to the twelve sent out two by two as well. Called and commissioned to proclaim “the kingdom come” they do the things that Jesus does, casting out demons, healing the sick and preaching the Jesus sermon. “The kingdom of God has come near. Repent and believe the good news.” And they receive the same reception as Jesus does. Aren’t you James and John, the fishermen, the sons of Zebedee? There is no indication that Jesus did any dust shaking when rejected so perhaps the instruction to shake the dust off their sandals has as much to do with the disciples not being discouraged as it does with the house that will not welcome them. But like the disciples sent out the message received is meant to move one from knowing to believing to doing. We might know a thing or two about Jesus and be able to recite the tenants of the faith as described in creeds and catechisms. Faith calls us to move beyond what we know in order to believe what cannot be known. Or in other words what you know becomes who you are and who you are becomes what you do and what you do looks more like the Jesus you know.
