In Luke 10:25-37, Jesus tells a story which has become widely known, even beyond Christian circles. The basic plot is this. A traveler is attacked half to death and left on the road; two religious leaders pass by, but an outsider has compassion and helps the left-for-dead traveler. The basic point of this basic plot is to demonstrate the nature of neighborly compassion.
This, of course, is an important lesson, but the story is too rich to be left at this familiar level.
