(20) Now then we are ambassadors for Christ--The preposition "for" implies the same representative character as in 2Corinthians 5:14-15. The preachers of the Word were acting on behalf of Christ; they were acting also in His stead. The thought or word meets us again in Ephesians 6:20. "I am an ambassador in bonds." The earlier versions (Tyndale, Geneva, Cranmer) give "messengers," the Rhemish "legates." "Ambassadors," which may be noted as singularly felicitous, first appears in the version of 1611. The word, derived from the mediaeval Latin ambasciator, and first becoming popular in the Romance languages, is found in Shakespeare, and appears to have come into prominence through the intercourse with France and Spain in the reign of Elizabeth.

We pray you in Christ's stead, be ye reconciled to God.--It will be seen, in this conclusion of the language of St. Paul as to the atonement, how entirely, on the one hand, he recognises the representative and vicarious character of the redeeming work of Christ; how entirely, on the other, he stands aloof from the speculative theories on that work which have sometimes been built upon his teaching. He does not present, as the system-builders of theology have too often done, the picture of the wrath of the Father averted by the compassion of the Son, or satisfied by the infliction upon Him of a penalty which is a quantitative equivalent for that due to the sins of mankind. The whole work, from his point of view, originates in the love of the Father, sending His Son to manifest that love in its highest and noblest form. He does not need to be reconciled to man. He sends His Son, and His Son sends His ministers to entreat them to be reconciled to Him, to accept the pardon which is freely offered. In the background there lies the thought that the death of Christ was in some way, as the highest act of Divine love, connected with the work of reconciliation; but the mode in which it was effective, is, as Butler says (Analogy, 2:5), "mysterious, and left, in part at least, unrevealed," and it is not wise to "endeavour to explain the efficacy of what Christ has done and suffered for us beyond what the Scripture has authorised."

Verse 20. - Now then. It is, then, on Christ's behalf that we are ambassadors. This excludes all secondary aims. St. Paul uses the same expression in Ephesians 6:20, adding with fine contrast that he is "an ambassador in fetters." As though God did beseech you by us; rather, as if God were exhorting you by our means. In Christ's stead; rather, we, on Christ's behalf, beseech you. Be ye reconciled to God. This is the sense of the embassy. The aorist implies an immediate acceptance of the offer of reconciliation.

5:16-21 The renewed man acts upon new principles, by new rules, with new ends, and in new company. The believer is created anew; his heart is not merely set right, but a new heart is given him. He is the workmanship of God, created in Christ Jesus unto good works. Though the same as a man, he is changed in his character and conduct. These words must and do mean more than an outward reformation. The man who formerly saw no beauty in the Saviour that he should desire him, now loves him above all things. The heart of the unregenerate is filled with enmity against God, and God is justly offended with him. Yet there may be reconciliation. Our offended God has reconciled us to himself by Jesus Christ. By the inspiration of God, the Scriptures were written, which are the word of reconciliation; showing that peace has been made by the cross, and how we may be interested therein. Though God cannot lose by the quarrel, nor gain by the peace, yet he beseeches sinners to lay aside their enmity, and accept the salvation he offers. Christ knew no sin. He was made Sin; not a sinner, but Sin, a Sin-offering, a Sacrifice for sin. The end and design of all this was, that we might be made the righteousness of God in him, might be justified freely by the grace of God through the redemption which is in Christ Jesus. Can any lose, labour, or suffer too much for Him, who gave his beloved Son to be the Sacrifice for their sins, that they might be made the righteousness of God in him?Now then we are ambassadors for Christ,.... Since God has made reconciliation by Christ, and the ministry of it is committed to us, we are ambassadors for him; we come with full powers from him, not to propose terms of peace, to treat with men about it, to offer it to them, but to publish and proclaim it as made by him: we represent him, and God who made it by him,

as though God did beseech you by us; to regard this embassy and message of peace, which we bring from him; to consider from whence it takes its rise, what methods have been used to effect it, and how it is accomplished; which should oblige to say and sing with the angels, "glory to God in the highest, on earth peace, and good will towards men"; and to behave in peaceable manner to all men, and one another:

we pray you in Christ's stead; representing him as if he was present before you:

be ye reconciled to God; you, who are new creatures, for whom Christ has died, and peace is made; you, the members of the church at Corinth, who upon a profession of faith have been taken into such a relation; be ye reconciled to all the dispensations of divine Providence towards you; let your wills bow, and be resigned to his, since he is the God of peace to you; and as you are reconciled by Christ as a priest, be reconciled to him as your King, and your God; to all his ordinances and appointments; to all the orders and laws of his house; conform in all things to his will and pleasure, which we, as his ambassadors, in his name and stead, have made known unto you. You ought to be all obedience to him, and never dispute anything he says or orders.
