Acts 28:31 “Boldly and without hindrance he preached the kingdom of God and taught about the Lord Jesus Christ.” Paul was a visitor in Rome who was directed by his Father.  Rome was not a Christian city with multiple Christian churches.  Yet, Paul did not live in fear while he taught and confessed truths of His Savior.  Paul knew the truth and knew others had to learn about the One True God.  Whether his words were approved or not he confessed what he knew was truth.  Certainly you and I can learn from Paul and confess the same truths Paul boldly confessed.
