Ephesians 6:20

“For which I am an ambassador in bonds, &c.] The character the apostle bore was that of an ambassador; and he was an ambassador from and for Christ, in his room and stead; he represented him, he was sent by him, and entrusted by him with the Gospel; he gave him it, and a commission to preach it, and furnished him with qualifications for it; such as knowledge and faithfulness wisdom and prudence, courage and greatness of mind; and made his embassy successful: and he was chiefly an ambassador to the Gentiles, which showed great condescension in Christ to send him to them, and base ingratitude in the despisers and rejecters of the Gospel, for which he was an ambassador; for the embassy Christ's…”

“For--Greek, as in Eph 6:19, "On behalf of which." an ambassador in bonds--a paradox. Ambassadors were held inviolable by the law of nations, and could not, without outrage to every sacred right, be put in chains. Yet Christ's "ambassador is in a chain!" The Greek is singular.

The singular is only used of the particular kind of custody described above; an undesigned…”

“For which I am an ambassador in bonds - In chains (see the margin); or in confinement. There is something especially touching in this. He was “an ambassador” - sent to proclaim peace to a lost world. But he was now in chains. An ambassador is a sacred character. No greater affront can be given to a nation than to put its ambassadors to death, or even to throw them into prison. But Paul says here that the unusual spectacle was witnessed of an ambassador seized, bound, confined, imprisoned; an ambassador who ought to have the privileges conceded to all such people, and to be permitted to go everywhere publishing the terms of mercy and salvation. See the word “ambassador” explained in the notes…”

“An ambassador in bonds - The ambassadors of men usually appear in great pomp. How differently does the ambassador of Christ appear! Ephesians 6:21”

“I am: Pro 13:17; Isa 33:7; Co2 5:20 bonds: or, a chain, Eph 3:1, Eph 4:1; Sa2 10:2-6; Act 26:29, Act 28:20; Phi 1:7, Phi 1:13, Phi 1:14; Ti2 1:16, Ti2 2:9; Plm 1:10 therein: or, thereof boldly: Eph 6:19; Isa 58:1; Jer 1:7, Jer 1:8, Jer 1:17; Eze 2:4-7; Mat 10:27, Mat 10:28; Act 5:29, Act 28:31; Col 4:4; Phi 1:20; Th1 2:2; Jo1 3:16; Jde 1:3 Ephesians 6:21”
