Why are the parables of Jesus so important?

We know that any teaching of the Lord Jesus is very important.  But why are the parables of Jesus so important?  It says in Matthew 13:34-35 (NKJV) “34 All these things Jesus spoke to the multitude in parables; and without a parable He did not speak to them, 35 that it might be fulfilled which was spoken by the prophet, saying:  “I will open My mouth in parables; I will utter things kept secret from the foundation of the world.””  You see when we had the Savior of the world here on earth, he shared things that were secret up until he revealed them to his people and mankind.  So the parables of Jesus are very important to study because they reveal secrets that were hidden up until the time the Lord Jesus revealed them.  They are still hidden to those who do not seek him and strive to understand Jesus teachings.
