Pastor "Mac" continues to talk about Jesus' talk with the Priests about who He is. Jesus tells the Priests about one son who is asked to go to the fields to work, but says he didn't want to go. He then changed his mind and went. The man's other son said he would go, but he did not go.
The main purpose of the story was that people may have done wrong in the past, but they have the Power to Change their mind and heart.
