We can learn and amass a great amount of data about a subject, but without understanding gained through application and contemplation that data has no real value beyond its potential.
For example, I've known many people with advanced degrees and many others with no formal education beyond high school or a few semesters in college.
Yet, it's often those with little formal education who have the greater understanding than those who have the advanced degree.
Not only that, without the understanding gained through application and contemplation, all that data can just cause problems. We too easily miss the warnings that the experienced but "uneducated" clearly see.
See Malcolm's rant in Jurassic Park by Michael Crichton (New York: Ballantine Books, 1990, pp.305-307) I quoted on my homepage here to get an idea of what I'm trying to say.
I think that difference in knowledge is why some people, no matter what they say or quote, seem to believe that supernatural only applies to Satan and his demons and that God officially suspended operations here on Earth with Jesus' death and won't begin again until He comes back.
I like the lines in the movie...
"Can we pet him?"
"Sure; he's a vegetarian."
