Mat Matthew, chapter The Gospel According to Matthew, chapter 13
Jesus explained that the parable about the kinds of soil illustrates four different ways people respond to his teaching.
Matthew 13:18-23
But because it does not penetrate deeply into their inner beings, they believe it for only a short time. They are like the plants that did not have deep roots. When they are treated badly and caused to suffer because they believe God’s message, they soon stop believing it.
