The image of Jesus as the Good Shepherd is familiar to most Christians. We can imagine what it must be like to wander away from the flock, to be lost and cold and out of reach of all that’s familiar. Few of us have a direct experience of God caring for us as the Good Shepherd. For most of us, that loving presence comes from the flesh-and-blood people in our lives. God reaches out to others through us just as he reached out to us through others.
