Hou looks at the transition the apostle Paul made from a Pharisee named Saul who was an enemy of the church to a converted Christian and a leading evangelist. He then compares this "Saul" with the Old Testament King Saul and discusses very interesting parallels. For example, Saul persecuted David; Paul persecuted the Son of David by persecuting the church. Also, how repentance is far more than just recognizing Christ.
