1. They heard about the man and the pigs (14-17)
The people of the town heard about the pigs. They came and saw the man who had terrified the neighborhood by his violent behavior sitting there, clothed and in his right mind. What an amazing change! But they didn't care about the man; they heard about the pigs and they were afraid of further material loss. They might have brought the sick and demon-possessed of the town to Jesus, but instead they asked Jesus to leave. Jesus never stays where he is not welcome.
2. Go, tell what the Lord has done for you (18-20)
The man wanted to go with Jesus. Perhaps he was tired of that heartless, materialistic region. But Jesus gave him a mission. He sent him back to tell his family and friends about God's mercy and grace in his life. He obeyed Jesus and went. He had become a servant of Jesus and a free man.
Application: Lord, help me to value people more than things; help me to tell the world about your grace and mercy.
One Word: Go and tell God's mercy
