" The Sermon on the Mount is the moral portrait of Jesus’ own people. Because this portrait doesn’t square with the church, this Sermon turns from instruction to indictment. To those ends—both instruction and indictment—this commentary has been written with the simple goal that God will use this book to lead us to become in real life the portrait Jesus sketched in the Sermon. "
