The ambassador is the NT's signature image of the Christian's public identity: "we are ambassadors for Christ, God making his appeal through us" (2 Cor 5:20). An ambassador does not speak on his own authority; he represents the sovereign. He does not live permanently in the foreign land; he is a guest with official standing. He carries the terms of his government; he does not modify them. Paul also calls himself "an ambassador in chains" (Eph 6:20), a phrase that presses the oddness of the post: Christ's representative often bears the shame of His sovereign's treatment. OT prophets functioned as ambassadors of the divine King to the nations and to Israel itself. Every Christian is now a royal embassy on foreign soil, with the message: "be reconciled to God."
AM-BAS'SA-DOR, n.
AM-BAS'SA-DOR, n. [Fr. ambassadeur.] (1.) A minister of the highest rank, sent by one sovereign to another to represent his person, to treat of affairs of state, and to negotiate peace or alliance. (2.) In Scripture, the Christian is called an ambassador for Christ, God making His appeal through the preacher, that men may be reconciled to God. As an ambassador speaks not his own mind but the mind of his sovereign, so the faithful Christian minister and witness speaks only what the Lord has committed to him, and seeks the King's glory, not his own.
2 Corinthians 5:20 — "Therefore, we are ambassadors for Christ, God making His appeal through us. We implore you on behalf of Christ, be reconciled to God."
Ephesians 6:20 — "For which I am an ambassador in chains, that I may declare it boldly, as I ought to speak."
Proverbs 13:17 — "A wicked messenger falls into trouble, but a faithful envoy brings healing."
2 Chronicles 32:31 — "And so in the matter of the envoys of the princes of Babylon, who had been sent to Him to inquire about the sign that had been done in the land, God left Him to Himself."
Modern evangelism often lacks ambassadorial dignity: either too aggressive (speaking as oneself, not as a sovereign's herald) or too apologetic (hedging the sovereign's terms).
An ambassador is not a salesman. He does not modify the terms to close the deal; he carries his sovereign's language intact and waits for a response. Modern evangelical culture swings between two errors. First, the aggressive cold-sales posture: push, pressure, count the decisions. Second, the apologetic hedge: soft-pedal sin, soft-pedal hell, soft-pedal the exclusivity of Christ to get a hearing. Both are ambassadorial malpractice. The biblical ambassador delivers the exact message of the King with courage and courtesy, accepts rejection without despair, speaks the gospel's genuine terms, and trusts the Sovereign with the outcome. Paul in chains was still an ambassador — perhaps more so. Live like an ambassador; speak for your King.

"Paul was an ambassador in chains. Your cultural discomfort for speaking Christ plainly is embassy duty, not exception."
