...."While some people were suspicious of what Jesus said the man in the story, with an unhealthy spirit, was not. He had been sitting in the synagogue for years and heard nothing from the scribes that would help change anything in his life. Jesus, on the other hand, was announcing a new way to live which countered false prophecies. He was demonstrating God’s victory over evil. One might say he took the air out of the demon.
Scholar Brendan Byrne suggests the demonized man represents everything that holds us back from moving forward with our lives. Jesus’s teachings and the exorcism of the unclean spirit both were acts of liberation.  Jesus freed up the man so he could regain his dignity as a human being."
