In Matthew 7 Jesus instructs His disciples not to “cast pearls before swine.” This proverb is often used to indicate the folly of giving something great to lousy people. Personally, I have a lot more sympathy for the pigs.
If I were a pig I would not want pearls. I couldn't use them. I could use slop or banana peels, but pearls have little utility for a pig. If someone were to cast pearls to me I would be upset that they gave me something that they should have known I could not use.
Jesus had a lot of “pearls” of wisdom, but He did not cast pearls before swine. The wisdom of Christ, although precious, always had a utility for His audience.
