Have you ever heard a joke and just didn't get it even when it was explained to you?
This was the state of the religious leaders who followed Jesus around trying to trip him up. Jesus spoke in stories called parables that spoke about how leaders like the scribes and Pharisees would reject him and his message. Because of their lust for power and predisposition to jealousy they simply did not get the messages contain in the parables. Here is a part of the passage from Isaiah that Jesus quotes about them:
"this people's heart has grown dull, and with their ears they can barely hear, and their eyes they have closed"But Jesus speaks something very different about those who follow him. He contrasts those who have hearts that are not dull, ears to hear and eyes to see with the religious leaders. He says that people who follow him will have more and those who oppose him have less. History seems to validate that idea.
I believe in you Lord. Help me to reject the things that dull my heart, my eyes and ears.
