The dream-stealing religious leaders did everything they could to rob that man of his dream. And his parents are not helpful. They know the issue is the identity of the healer, but fearful of the wolfpack they throw the scent back on their own son. The religious leaders might as well have said, Look, religion should not make you full of life. It should be serious business.
Religion is about obeying the rules.
In effect Jesus says to them, You can have your rules. I'll keep giving people their dream of an adventurous faith. Christ is the dream-giver who wants us to listen to God's dream for us, so we can run like children in fields of God's grace. Predictability and faith rarely coexist. What characterized Jesus and was his utter unpredictability.
