 Here's a good example of that. Jesus was preaching to a large crowd of people one day, and as he often did, he was using a parable to teach a lesson. A parable is a physical story that teaches a parallel spiritual truth. The meaning of the physical story gives you insight into the spiritual truth. So Jesus was using a parable to teach the crowds, but he didn't explain the meaning of the parable. When the story was finished, most of the crowd walked away.
