A famous quote from Martin Luther King, Jr. speaks of the arc of the moral universe being long but bending toward justice. Dr. King drew on his faith that saw the world inevitably ending up at where God intends. But people can certainly act in ways that lead societies a direction incompatible with Dr. King's arc and with God's kingdom. In this gospel reading, Jesus' call to repent, meaning a change of mind and direction, is paired with his calling the first disciples. Following Jesus means going with him and learning his ways, ways that trace an arc toward God's future, and arc often at odds with that traced by those in power.
