12 We are not commending ourselves to you again, but giving you an opportunity to boast about us, so that you may be able to answer those who boast in outward appearance and not in the heart. 13 For if we are beside ourselves, it is for God; if we are in our right mind, it is for you. 14 For the love of Christ urges us on, because we are convinced that one has died for all; therefore all have died. 15 And he died for all, so that those who live might live no longer for themselves, but for him who died and was raised for them.

16 From now on, therefore, we regard no one from a human point of view; even though we once knew Christ from a human point of view, we know him no longer in that way. 17 So if anyone is in Christ, there is a new creation: everything old has passed away; see, everything has become new! 18 All this is from God, who reconciled us to himself through Christ, and has given us the ministry of reconciliation; 19 that is, in Christ God was reconciling the world to himself, not counting their trespasses against them, and entrusting the message of reconciliation to us. 20 So we are ambassadors for Christ, since God is making his appeal through us; we entreat you on behalf of Christ, be reconciled to God. 21 For our sake he made him to be sin who knew no sin, so that in him we might become the righteousness of God.

Commentary on 2 Corinthians 5:9-15

(Read 2 Corinthians 5:9-15)

The apostle quickens himself and others to acts of duty. Well-grounded hopes of heaven will not encourage sloth and sinful security. Let all consider the judgment to come, which is called, The terror of the Lord. Knowing what terrible vengeance the Lord would execute upon the workers of iniquity, the apostle and his brethren used every argument and persuasion, to lead men to believe in the Lord Jesus, and to act as his disciples. Their zeal and diligence were for the glory of God and the good of the church. Christ's love to us will have a like effect upon us, if duly considered and rightly judged. All were lost and undone, dead and ruined, slaves to sin, having no power to deliver themselves, and must have remained thus miserable for ever, if Christ had not died. We should not make ourselves, but Christ, the end of our living and actions. A Christian's life should be devoted to Christ. Alas, how many show the worthlessness of their professed faith and love, by living to themselves and to the world!

Commentary on 2 Corinthians 5:16-21

(Read 2 Corinthians 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?
