Not boasting of things {m} without our measure, that is, of other men's labours; but having hope, when your faith is increased, that we shall be enlarged by you according to our rule abundantly,

(m) As though God had divided the whole world among the apostles to be governed.

People's New Testament

10:15 Not boasting... of other men's labours. It was Paul's uniform course to preach where no one before him had preached the gospel.

Having hope, etc. The passage expresses the hope that his success at Corinth and the support of the church will enable him to carry the gospel beyond. That city, at this time, was the western limit of his work. The thought is made clear by the next verse.

Wesley's Notes

10:15 Having hope, now your faith is increased - So that you can the better spare us. To be enlarged by you abundantly - That is, enabled by you to go still further.

King James Translators' Notes

enlarged...: or, magnified in you

Jamieson-Fausset-Brown Bible Commentary

15. "Not boasting to unmeasured bounds (that is, not exceeding our own bounds by boasting) of (literally, 'in') other men's labors."

when-"As your faith goes on increasing." The cause of his not yet reaching with the Gospel the regions beyond Corinth, was the weakness as yet of their faith. He desired not to leave the Corinthians before the proper time, and yet not to put off preaching to others too long.

enlarged by you-Greek, "in your case." Our success in your case will give us an important step towards further progress beyond you (2Co 10:16).

according to our rule-according to our divinely assigned apportionment of the area or sphere of our work; for "we stretch not ourselves beyond our measure" (2Co 10:14).

abundantly-Greek, "unto exceeding abundance": so as to exceed the limits we have yet reached (2Co 10:16).

Matthew Henry's Concise Commentary

10:12-18 If we would compare ourselves with others who excel us, this would be a good method to keep us humble. The apostle fixes a good rule for his conduct; namely, not to boast of things without his measure, which was the measure God had distributed to him. There is not a more fruitful source of error, than to judge of persons and opinions by our own prejudices. How common is it for persons to judge of their own religious character, by the opinions and maxims of the world around them! But how different is the rule of God's word! And of all flattery, self-flattery is the worst. Therefore, instead of praising ourselves, we should strive to approve ourselves to God. In a word, let us glory in the Lord our salvation, and in all other things only as evidences of his love, or means of promoting his glory. Instead of praising ourselves, or seeking the praise of men, let us desire that honour which cometh from God only.

Matthew Henry's Whole Bible Commentary

Verses 12-18

In these verses observe,

I. The apostle refuses to justify himself, or to act by such rules as the false apostles did, v. 12. He plainly intimates that they took a wrong method to commend themselves, in measuring themselves by themselves, and comparing themselves among themselves, which was not wise. They were pleased, and did pride themselves, in their own attainments, and never considered those who far exceeded them in gifts and graces, in power and authority; and this made them haughty and insolent. Note, If we would compare ourselves with others who excel us, this would be a good method to keep us humble; we should be pleased and thankful for what we have of gifts or graces, but never pride ourselves therein, as if there were none to be compared with us or that did excel us. The apostle would not be of the number of such vain men: let us resolve that we will not make ourselves of that number.

II. He fixes a better rule for his conduct, namely, not to boast of things without his measure, which was the measure God had distributed to him, v. 13. His meaning is, either that he would not boast of more gifts or graces, or power and authority, than God had really bestowed on him; or, rather, that he would not act beyond his commission as to persons or things, nor go beyond the line prescribed to him, which he plainly intimates the false apostles did, while they boasted of other men's labors. The apostle's resolution was to keep within his own province, and that compass of ground which God had marked out for him. His commission as an apostle was to preach the gospel every where, especially among the Gentiles, and he was not confined to one place; yet he observed the directions of Providence, and the Holy Spirit, as to the particular places whither he went or where he did abide.

III. He acted according to this rule: We stretch not ourselves beyond our measure, v. 14. And, particularly, he acted according to this rule in preaching at Corinth, and in the exercise of his apostolical authority there; for he came thither by divine direction, and there he converted many to Christianity; and, therefore, in boasting of them as his charge, he acted not contrary to his rule, he boasted not of other men's labours, v. 15.

IV. He declares his success in observing this rule. His hope was that their faith was increased, and that others beyond them, even in the remoter parts of Achaia, would embrace the gospel also; and in all this he exceeded not his commission, nor acted in another man's line.

V. He seems to check himself in this matter, as if he had spoken too much in his own praise. The unjust accusations and reflections of his enemies had made it needful he should justify himself; and the wrong methods they took gave him good occasion to mention the better rule he had observed: yet he is afraid of boasting, or taking any praise to himself, and therefore he mentions two things which ought to be regarded:-1. He that glorieth should glory in the Lord, v. 17. If we are able to fix good rules for our conduct, or act by them, or have any good success in so doing, the praise and glory of all are owing unto God. Ministers in particular must be careful not to glory in their performances, but must give God the glory of their work, and the success thereof. 2. Not he that commendeth himself is approved, but he whom the Lord commendeth, v. 18. Of all flattery, self-flattery is the worst, and self-applause is seldom any better than self-flattery and self-deceit. At the best, self-commendation is no praise, and it is oftentimes as foolish and vain as it is proud; therefore, instead of praising or commending ourselves, we should strive to approve ourselves to God, and his approbation will be our best commendation.
