Read Romans 15:14-22
Paul was enthusiastic about what God had done through him. Being proud of God’s work is not a sin: It is worship. If you are not sure whether your pride is selfish or not, ask yourself this question: Am I just as proud of what God is doing through other people as of what He is doing through me?
Illyricum was a Roman territory on the Adriatic Sea between present day Italy and Greece. It covered about as much land mass as Wyoming.
Paul wanted to visit the church at Rome, but he had delayed his visit because he had heard reports about the believers there and knew they were doing well on their own. It was more important for him to preach in areas that had not yet heard the Gospel.
