The chapter starts out with several having faith..then being healed. Jesus goes on to heal many others and drive out demons. Once again Matthew shows that this is a fulfillment of prophecy. "He took our weaknesses and carried our diseases."
He then challenged those that follow him to put him first. No turning back to the things of this life...no putting off following him. Do it NOW.
Jesus then calms the raging seas. He has power over nature! The disciples, of course, are scared...and Jesus rebukes them for their lack of faith.
The chapter ends with him driving the demons out of two men and into a herd of pigs. The pigs ran over the edge of a cliff and drowned. The owner of the pigs let the town know what happened...and they all wanted Jesus to leave.
