5:20 Then we are ambassadors for Christ. We have God's message, are his authorized messengers, and speak for God, beseeching you for Christ, and in his name, to be
reconciled to God by repentance and the obedience of faith.
5:20 Therefore we are ambassadors for Christ - we beseech you in Christ's stead - Herein the apostle might appear to some transported beyond himself. In general he uses a more calm, sedate kind of exhortation, as in the beginning of the next chapter . What unparalleled condescension and divinely tender mercies are displayed in this verse ! Did the judge ever beseech a condemned criminal to accept of pardon? Does the creditor ever beseech a ruined debtor to receive an acquittance in full? Yet our almighty Lord, and our eternal Judge, not only vouchsafes to offer these blessings, but invites us, entreats us, and, with the most tender importunity, solicits us, not to reject them.
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?
