In these verses we have an account of the apostle's general errand and exhortation to all to whom he preached in every place where he came, with the several arguments and methods he used. Observe,
I. The errand or exhortation itself, namely, to comply with the gospel offers of reconciliation - that, being favoured with the gospel, they would not receive this grace of God in vain, Co2 6:1. The gospel is a word of grace sounding in our ears; but it will be in vain for us to hear it, unless we believe it, and comply with the end and design of it. And as it is the duty of the ministers of the gospel to exhort and persuade their hearers to accept of grace and mercy which are offered to them, so they are honoured with this high title of co-workers with God. Note, 1. They must work; and must work for God and his glory, for souls and their good: and they are workers with God, yet under him, as instruments only; however, if they be faithful, they may hope to find God working with them, and their labour will be effectual. 2. Observe the language and way of the spirit of the gospel: it is not with roughness and severity, but with all mildness and gentleness, to beseech and entreat, to use exhortations and arguments, in order to prevail with sinners and overcome their natural unwillingness to be reconciled to God and to be happy for ever.
II. The arguments and method which the apostle used. And here he tells them,
1. The present time is the only proper season to accept of the grace that is offered, and improve that grace which is afforded: NOW is the accepted time, NOW is the day of salvation, Co2 6:2. The gospel day is a day of salvation, the means of grace the means of salvation, the offers of the gospel the offers of salvation, and the present time the only proper time to accept of these offers: Today, while it is called today. The morrow is none of ours: we know not what will be on the morrow, nor where we shall be; and we should remember that present seasons of grace are short and uncertain, and cannot be recalled when they are past. It is therefore our duty and interest to improve them while we have them, and no less than our salvation depends upon our so doing.
2. What caution they used not to give offence that might hinder the success of their preaching: Giving no offence in any thing, Co2 6:3. The apostle had great difficulty to behave prudently and inoffensively towards the Jews and Gentiles, for many of both sorts watched for his halting, and sought occasion to blame him and his ministry, or his conversation; therefore he was very cautious not to give offence to those who were so apt to take offence, that he might not offend the Jews by unnecessary zeal against the law, nor the Gentiles by unnecessary compliances with such as were zealous for the law. He was careful, in all his words and actions, not to give offence, or occasion of guilt or grief. Note, When others are too apt to take offence, we should be cautious lest we give offence; and ministers especially should be careful lest they do any thing that may bring blame on their ministry or render that unsuccessful.
3. Their constant aim and endeavor in all things to approve themselves faithful, as became the ministers of God, Co2 6:4. We see how much stress the apostle upon all occasions lays on fidelity in our work, because much of our success depends upon that. His eye was single, and his heart upright, in all his ministrations; and his great desire was to be the servant of God, and to approve himself so. Note, Ministers of the gospel should look upon themselves as God's servants or ministers, and act in every thing suitably to that character. So did the apostle, (1.) By much patience in afflictions. He was a great sufferer, and met with many afflictions, was often in necessities, and wanted the conveniences, if not the necessaries, of life; in distresses, being straitened on every side, hardly knowing what to do; in stripes often (Co2 11:24); in imprisonments; in tumults raised by the Jews and Gentiles against him; in labours, not only in preaching the gospel, but in travelling from place to place for that end, and working with his hands to supply his necessities; in watchings and in fastings, either voluntary or upon a religious account, or involuntary for the sake of religion: but he exercised much patience in all, Co2 6:4, Co2 6:5. Note, [1.] It is the lot of faithful ministers often to be reduced to great difficulties, and to stand in need of much patience. [2.] Those who would approve themselves to God must approve themselves faithful in trouble as well as in peace, not only in doing the work of God diligently, but also in bearing the will of God patiently. (2.) By acting from good principles. The apostle went by a good principle in all he did, and tells them what his principles were (Co2 6:6, Co2 6:7); namely, pureness; and there is no piety without purity. A care to keep ourselves unspotted from the world is necessary in order to our acceptance with God. Knowledge was another principle; and zeal without this is but madness. He also acted with long-suffering and kindness, being not easily provoked, but bearing with the hardness of men's hearts, and hard treatment from their hands, to whom he kindly endeavoured to do good. He acted under the influence of the Holy Ghost, from the noble principle of unfeigned love, according to the rule of the word of truth, under the supports and assistances of the power of God, having on the armour of righteousness (a consciousness of universal righteousness and holiness), which is the best defence against the temptations of prosperity on the right hand, and of adversity on the left. (3.) By a due temper and behaviour under all the variety of conditions in this world, Co2 6:8-10. We must expect to meet with many alterations of our circumstances and conditions in this world; and it will be a great evidence of our integrity if we preserve a right temper of mind, and duly behave ourselves, under them all. The apostles met with honour and dishonour, good report and evil report: good men in this world must expect to meet with some dishonour and reproaches, to balance their honour and esteem; and we stand in need of the grace of God to arm us against the temptations of honour on the one hand, so as to bear good report without pride, and of dishonour on the other hand, so as to bear reproaches without impatience or recrimination. It should seem that persons differently represented the apostles in their reports; that some represented them as the best, and others as the worst, of men: by some they were counted deceivers, and run down as such; by others as true, preaching the gospel of truth, and men who were true to the trust reposed in them. They were slighted by the men of the world as unknown, men of no figure or account, not worth taking notice of; yet in all the churches of Christ they were well known, and of great account: they were looked upon as dying, being killed all the day long, and their interest was thought to be a dying interest; "and yet behold," says the apostle, "we live, and live comfortably, and bear up cheerfully under all our hardships, and go on conquering and to conquer." They were chastened, and often fell under the lash of the law, yet not killed: and though it was thought that they were sorrowful, a company of mopish and melancholy men, always sighing and mourning, yet they were always rejoicing in God, and had the greatest reason to rejoice always. They were despised as poor, upon the account of their poverty in this world; and yet they made many rich, by preaching the unsearchable riches of Christ. They were thought to have nothing, and silver and gold they had none, houses and lands they had none; yet they possessed all things: they had nothing in this world, but they had a treasure in heaven. Their effects lay in another country, in another world. They had nothing in themselves, but possessed all things in Christ. Such a paradox is a Christian's life, and through such a variety of conditions and reports lies our way to heaven; and we should be careful in all these things to approve ourselves to God.

By pureness - Εν ἁγνοτητι· In simplicity of intention, and purity of affection; together with that chastity and holiness of life which the Gospel enjoins.
By knowledge - Of the Divine mysteries.
By long-suffering - Under all provocations.
By kindness - To our most virulent persecutors, and to all men.
By the Holy Ghost - There are doubts among learned men whether the apostle here means that Spirit who is called the third person of the holy Trinity; or some grace, disposition, or quality of the soul, which was thus denominated, as implying a spirit wholly purified, and fitted to be a habitation of God.
Schoettgen quotes a passage from Rabbi Bechai, in which it appears to him to have this latter meaning: "Rabbi Pinchas, the son of Jair, said: Reflection leads to sedulity; sedulity to innocence; innocence to abstinence; abstinence to cleanness; cleanness to sanctity; sanctity to the fear of sin; fear of sin to humility; humility to piety; and piety to the Holy Spirit. Of these ten virtues five are external, or belong to the body; and five internal, or belonging to the soul; but all men prefer the tenth, which is רוח הקדש ruach hakkodesh, the Holy Spirit." Even allowing Rabbi Pinchas to be a person on whose judgment we could rely, and whose authority was decisive, there does not appear to me any reason why we should depart from the usual meaning of the term from any thing that is said here. It appears to me plain enough that the rabbi means the constant indwelling of the Holy Spirit; and St. Paul, in this place, may have the same thing in view, and with it the various gifts of the Holy Spirit by which he was enabled to work miracles.
By love unfeigned - Εν αγαπῃ ανυποκριτῳ· Love without hypocrisy; such as disposed us at all times to lay down our life for the brethren, and to spend and be spent for the glory of God and the good of mankind.

By the word of truth,.... By preaching the Gospel, truly, sincerely, without any adulteration of it, which comes from the God of truth, has for its subject matter Christ, who is the truth, and into which ministers are guided by the Spirit of truth, and every doctrine of which is truth:

by the power of God; accompanying the word to the conversion and salvation of multitudes of souls; or by the signs, wonders, and miracles which were wrought for the confirmation of it:

by the armour of righteousness, on the right hand, and on the left: meaning, either the whole armour of God, with which a Christian is all over clothed from head to foot, and in the strength of Christ may engage any adversary without fear; or else particularly the sword of the Spirit in the right hand, and the shield of faith in the left, whereby both the offensive and defensive part may be acted; or, as others think, uprightness of conscience, and holiness of life and conversation; with which being blessed, though on the one hand he meets with prosperity, and on the other hand with adversity, he is not lifted up with the one, nor cast down with the other; he is moved by neither, but passes on unconcerned.

By . . . by, &c.--rather, as Greek, "In . . . in," implying not the instrument, but the sphere or element in which his ministry moved.

knowledge--spiritual: in Gospel mysteries, unattainable by mere reason (Co1 2:6-16; Co2 3:6, Co2 3:17-18).

long-suffering . . . kindness--associated with "charity" or "love" (Co1 13:4), as here.

by the Holy Ghost--in virtue of His influences which produce these graces, and other gifts, "love unfeigned" being the foremost of them.
