Parables are short stories that illustrate a lesson or principle through examples of human characters and their actions. They differ from fables which feature animals. The word parable comes from the Greek meaning "to throw alongside" or a comparison. Examples of parables include stories from the Bible like the Good Samaritan and Prodigal Son which use metaphorical language to discuss complex ideas. Parables provide guidance on proper behavior and beliefs in an easily understood narrative form.
