Why did Jesus speak in parables? Why was he subtle, indirect, and secretive? Because his message wasn't merely aimed at conveying information. It sought to precipitate something more important: the spiritual transformation of the hearers. The form of parable helps to shape a heart that is willing to enter an ongoing, interactive, persistent relationship of trust in the teacher. It beckons the hearer to explore new territory. It helps form a heart that is humble enough to admit it doesn't already understand and is thirsty enough to ask questions. In other words, a parable renders its hearers not as experts, not as know-it-alls, not as scholars . . . but as children.Brian McLaren, The Secret Message of Jesus, 46, 47.
Now do some of the most famous sayings of Jesus begin to make more sense- about the kingdom of God belonging to children, about needing to become like a little child to enter the kingdom, about needing to be born again? Children are dependent, not independent. They can't learn unless they ask questions of people they trust. Their thirst for knowledge expresses itself in an unquenchable curiosity, a passionate inquisitiveness.
