The man talked about it so much and told so many people, that Jesus could no longer go openly into a town. He had to stay away from the towns, but people still came to him from everywhere.
But Jesus would not let him. Instead, he said, “Go home to your family and tell them how much the Lord has done for you and how good he has been to you.”
People who don't take care of their relatives, and especially their own families, have given up their faith. They are worse than someone who doesn't have faith in the Lord.
