The Apostle Paul is in prison in Rome. He believes he's there for the "defense and confirmation" of the Gospel of Jesus Christ. He hopes that means he will be able to preach to Nero and then be free to complete his mission by going as far west as the Empire goes (Spain). He also knows it's likely he will remain in jail until Nero decides he should be executed. So it could be that his suffering, endurance, and death will be his witness of faith. He uses his time well, composing letters to congregations he has visited. Through these letters he shares, with great passion what he believes is essential for the present and future of Christ's disciples. We read the first words of his letter to the Philippians, Philippians 1:1-18.
