I teach legal writing classes at a law school--I have for a couple of years now. When we're talking about writing a statement of facts for a legal brief, I have students do a little exercise with the story of the Three Little Pigs. Using the same facts as they know from the original story, I have them try to tell the story from the wolf's point of view. The point is to learn to frame facts and emphasize and de-emphasize things in order to affect the way the audience views your client.
What I notice about this exercise is that every single time, my students go from this glazed look of mild disinterest or sleepiness to complete engagement. Even though it's a silly exercise and the students can barely understand why we're talking about a fairy tale in law school, the minute we start creatively engaging with a narrative, they light up.
Story is the language of our culture.
Many missions resources talk about how important it is when you're entering a new culture to learn the heart-language of the culture. That even if you're in a country where the trade language is French, for example, to really communicate to the hearts of people, you've got to learn their dialect--you've got to learn to communicate in the language that is dearest to their heart and soul.
I think that the language of story is that for our time and our culture. Maybe it is for all times and cultures, I don't know. But learning to engage with people through story opens up something inside of people that allows your words to penetrate to a person's very soul.
