Cost of Discipleship by Bonhoeffer Peterhorne
The primary goal in studying this material is to expose the church to the concept of “cheap” and “costly” grace. Jesus warned of the destiny of certain false disciples. What is their fault, and why does Jesus reject them? Nothing these false disciples claim to have done is challenged by Jesus. It seems their description is accurate. They did real prophecy and miracles in Jesus’ name. So what did they do wrong? Presumably, given the fruit before and foundations after, they didn’t do Jesus’ teaching. Since these warnings come at the end of the Sermon on the Mount it’s reasonable to say that these false disciples do not live their lives in accordance with the teachings Jesus has just given regarding the kingdom of God.
