Jesus was creating a big mess.  He was healing people, casting out demons and letting people know that he was the way to the Father.  His enemies and his opposition were divided.  Almost all of them wanted to hate him but some of his enemies took pause.  Why?  Because they couldn’t refute the blind seeing.

19 The Jews who heard these words were again divided. 20 Many of them said, “He is demon-possessed and raving mad. Why listen to him?”
21 But others said, “These are not the sayings of a man possessed by a demon. Can a demon open the eyes of the blind?” 

The couldn’t refute what they saw and it messed with them.  It divided them.  Because the healings validated his message.   And I think that is one of the main purposes of healing, not only to allow God to love on people but also to validate the message.  It sure challenged the thinking of the Jews.
