Make a list of the characters in the story. Keep in mind that the Jews (the Traveler) and the Samaritans were traditionally enemies, or at least rivals.
Take a 5-30 minute walk in silence. As you walk, imagine you are traveling the road from Jerusalem to Jericho. As you walk, try to adopt the perspective of each character in the story. Imagine: what are they thinking? what are they feeling? what is their motivation?
After your walk, take some time to journal or discuss your insights with others. What came to mind as you walked? If you were to re-cast the parable with characters from your real, modern-day life, who would the characters be? Who would you be?
