Jesus did not walk by the Sea of Galilee and shout to fishermen, “Have faith!” Instead, he asked them to do something: “Follow me.” When they followed, he gave them more things to do. At first, he demonstrated what he wanted them to do. Then he did it with them. Finally, he sent them out to do it themselves, telling them to proclaim God’s reign and cure the sick. When they returned from this first mission, they could not believe what had happened. They discovered that proclaiming the kingdom was not a matter of teaching doctrine; rather, the kingdom was a matter of imitating Jesus’s actions. Jesus did not tell them to have faith. He pushed them into the world to practice faith. The disciples did not hope the world would change. They changed it. And, in doing so, they themselves changed.
