Parables and the Narrative Paradigm

The Narrative Paradigm shows the power of story.  This is woven throughout the Bible.  Most of the Bible is made up of individual stories and the majority of Jesus teaching was done through parables or short stories.  No only does a story, myth or parable,  help us to better see the value in a lesson, we remember story better.  Facts take memorization, but story naturally sticks with us, although the words exactly may fade the lesson will stay.  I remember very little from and 8th grade latin class, but can tell you exactly what the books I was read as a young child were about.  How would the lessons that Lewis portrays through his myth differ if they were not told through story?  Would the parables of Jesus have less value and be less understood?
