“For which I am an ambassador in bonds: that therein I may speak boldly, as I ought to speak.”
King James Version (KJV)
6:20 An ambassador in bonds - The ambassadors of men usually appear in great pomp. How differently does the ambassador of Christ appear!
Eph 6:20 For which. The gospel. I am an ambassador in bonds. As an ambassador is sent to a foreign court to declare the will of the king, so Paul, though in chains, was Christ's ambassador sent to Rome to declare the will of his King.
