{8} For the love of Christ {l} constraineth us; because we thus judge, that if {m} one died for all, then were all dead:

(8) He continues dismissing all suspicion of desire of estimation and boasting. For the love of Christ, he says, compels us to this, that seeing he died for us all, who were dead when as we lived to ourselves (that is, while we were yet given to these earthly affections) we in like sort should consecrate our whole life which we have received from him, to him. That is, being endued with the Holy Spirit to this end and purpose, that we should meditate upon nothing but that which is heavenly.

(l) Wholly possesses us.

(m) He speaks here of sanctification, by which it comes to pass that Christ lives in us.

People's New Testament

5:14 For the love of Christ constraineth us. It was the power that moved him in all his conduct.

If one died for all, then were all dead. I thus judge that if Christ died for all, all in Christ have died with him to a life of sin. Baptized into his death we must be dead to sin. The next verse shows that this is the meaning. Compare Ro 6:3,4,6,11 Ga 5:4.

Wesley's Notes

5:14 For the love of Christ - To us, and our love to him. Constraineth us - Both to the one and the other; beareth us on with such a strong, steady, prevailing influence, as winds and tides exert when they waft the vessel to its destined harbour. While we thus judge, that if Christ died for all, then are all, even the best of men, naturally dead - In a state of spiritual death, and liable to death eternal. For had any man been otherwise, Christ had not needed to have died for him.

Jamieson-Fausset-Brown Bible Commentary

14. For-Accounting for his being "beside himself" with enthusiasm: the love of Christ towards us (in His death for us, the highest proof of it, Ro 5:6-8), producing in turn love in us to Him, and not mere "terror" (2Co 5:11).

constraineth us-with irresistible power limits us to the one great object to the exclusion of other considerations. The Greek implies to compress forcibly the energies into one channel. Love is jealous of any rival object engrossing the soul (2Co 11:1-3).

because we thus judge-literally, "(as) having judged thus"; implying a judgment formed at conversion, and ever since regarded as a settled truth.

that if-that is, that since. But the oldest manuscripts omit "if." "That one died for all (Greek, 'in behalf of all')." Thus the following clause will be, "Therefore all (literally, 'the all,' namely, for whom He 'died') died." His dying is just the same as if they all died; and in their so dying, they died to sin and self, that they might live to God their Redeemer, whose henceforth they are (Ro 6:2-11; Ga 2:20; Col 3:3; 1Pe 4:1-3).

Matthew Henry's Concise Commentary

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!

Matthew Henry's Whole Bible Commentary

Verses 12-15

Here observe, I. The apostle makes an apology for seeming to commend himself and his fellow-labourers (v. 13), and tells them, 1. It was not to commend themselves, nor for their own sakes, that he had spoken of their fidelity and diligence in the former verses; nor was he willing to suspect their good opinion of him. But, 2. The true reason was this, to put an argument in their mouths wherewith to answer his accusers, who made vain boastings, and gloried in appearances only; that he might give them an occasion to glory on their behalf, or to defend them against the reproaches of their adversaries. And if the people can say that the word has been manifested to their consciences, and been effectual to their conversion and edification, this is the best defence they can make for the ministry of the word, when they are vilified and reproached.

II. He gives good reasons for their great zeal and diligence. Some of Paul's adversaries had, it is likely, reproached him for his zeal and fervour, as if he had been a madman, or, in the language of our days, a fanatic; they imputed all to enthusiasm, as the Roman governor told him, Much learning has made thee mad, Acts 26:24. But the apostle tells them, 1. It was for the glory of God, and the good of the church, that he was thus zealous and industrious: "Whether we be beside ourselves, or whether we be sober (whether you or others do think the one or the other), it is to God, and for his glory: and it is for your cause, or to promote your good," v. 13. If they manifested the greatest ardour and vehemency at some times, and used the greatest calmness in strong reasonings at other times, it was for the best ends; and in both methods they had good reason for what they did. For, 2. The love of Christ constrained them, v. 14. They were under the sweetest and strongest constraints to do what they did. Love has a constraining virtue to excite ministers and private Christians in their duty. Our love to Christ will have this virtue; and Christ's love to us, which was manifested in this great instance of his dying for us, will have this effect upon us, if it be duly considered and rightly judged of. For observe how the apostle argues for the reasonableness of love's constraints, and declares, (1.) What we were before, and must have continued to be, had not Christ died for us: We were dead, v. 14. If one died for all, then were all dead; dead in law, under sentence of death; dead in sins and trespasses, spiritually dead. Note, This was the deplorable condition of all those for whom Christ died: they were lost and undone, dead and ruined, and must have remained thus miserable for ever if Christ had not died for them. (2.) What such should do, for whom Christ died; namely, that they should live to him. This is what Christ designed, that those who live, who are made alive unto God by means of his death, should live to him that died for them, and rose again for their sakes also, and that they should not live to themselves, v. 15. Note, We should not make ourselves, but Christ, the end of our living and actions: and it was one end of Christ's death to cure us of this self-love, and to excite us always to act under the commanding influence of his love. A Christian's life should be consecrated to Christ; and then do we live as we ought to live when we live to Christ, who died for us.
