Matthew 13:10-15

Then his disciples approached Jesus and asked, “Why do you always speak to people in these hard-to-understand parables?” He explained, “You’ve been given the intimate experience of insight into the hidden mysteries of the realm of heaven’s kingdom, but they have not. For everyone who listens with an open heart will receive progressively more revelation until he has more than enough. But those who don’t listen with an open, teachable heart, even the understanding that they think they have will be taken from them. That’s why I teach the people using parables, because they think they’re looking for truth, yet because their hearts are unteachable, they never discover it. Although they will listen to me, they never fully perceive the message I speak. The prophecy of Isaiah describes them perfectly: Although they listen carefully to everything I speak, they don’t understand a thing I say. They look and pretend to see, but the eyes of their hearts are closed. Their minds are dull and slow to perceive, their ears are plugged and are hard of hearing, and they have deliberately shut their eyes to the truth. Otherwise they would open their eyes to see, and open their ears to hear, and open their minds to understand. Then they would turn to me and I would instantly heal them.
