When you read through the chapters of Romans, it quickly becomes clear that Paul was trying to help the believers in the church at Rome come to a thorough understanding of sound doctrine. He wanted them to be able to understand deeper details about our faith so that their love for one another would grow and their appreciation for the work Christ has accomplished on our behalf would be strengthened. We don't need to be ashamed of Jesus. Rather, we can be joyful and grateful for who He is and what He does on our behalf.
