Ephesians 6:20. “For which I am an ambassador in bonds: that therein I may speak boldly, as I ought to speak.”
Paul wrote this letter to the Ephesian church from a position of bondage. He was a prisoner of Rome, because he would not stop preaching Christ as God. In Rome, Caesar was God. Paul would eventually die for his boldness in continuing to speak boldly for the sake of the gospel.
I’ve always loved this phrase, ambassador in bonds. It teaches us that we can still maintain our testimony for Christ, still preach the gospel, still offer those around us the freedom of the gospel of Jesus Christ.
Paul knew what he ought to do, and he did it.
