Theological reflection (that I find troubling so I'm going to skip over) followed by action. Jesus sees a problem that needs to be solved, so he gets to work immediately.
Notice that the blind man did not ask Jesus for help.
Onlookers don't accept that a miracle has occurred. Their responses include questioning whether it happened at all to asking how it did happen. When the no-longer-blind man tells them that and how Jesus cured his blindness, they wanted to know where Jesus was now.
Did they want to thank him? Did they want him to do something for them now? Did they want to learn how to help other people who needed it?
Do we recognize miracles?
What is our reaction to someone's being healed? What do we want to know? Why?
Can we remember (or imagine) being brought out of something as difficult as blindness?
