God's work was displayed in the blind man because Jesus healed him by restoring his sight.  God's work was evident in the blind man because God created him blind so Jesus could heal him.  He was not born bind because he or his parents had sinned; he was born for the express purpose of being healed by Christ!  Praise God!! The formerly blind man was an example of the healing power of Christ.  God has a purpose  for us all!!
