Asked by a persistent reporter to define the meaning of jazz, legendary trumpeter Louis Armstrong is reputed to have answered, "If you have to ask the question, you'll never know." Something similar is true of Jesus' revelation of himself in our lesson. We do not reach Jesus by dint of our own effort. We know him only because he chooses to reveal himself to us. He does so not dramatically and with power, but humbly and personally. The risen Jesus does not appear to the rich and famous, the movers and shakers of that time. He does not show up before the throne of the emperor in Rome, demanding to be vindicated. Rather, he falls in beside a couple of dispirited wanderers who are wending their way home after having their hopes dashed.
