From The Gospel of Matthew by Curtis Mitch and Edward Sri, commenting on Matthew 13:4-17:
See and hear are key words in this section. It is not enough to see and hear Christ’s words physically. One must follow him. Many see his miracles and hear his teaching, but still refuse to follow him. In contrast, Jesus’ disciples have eyes and ears that are blessed—a word recalling the beatitudes that showcase the fortunate situation of those who follow Christ. The disciples are blessed because they truly see, hear, and understand. They respond from the heart to Christ’s message, follow him, and are given explanations that help them understand the meaning of the parables.
