(15) Not boasting of things without our measure . . .--The words are not merely defensive. He presses home the charge of intrusion. They, not he, were finding ground for their boasts in other men's labours. The context leads, however, to the conclusion that it was a charge that had been brought against him. They had spoken of him as pushing on from point to point, as with a measureless ambition. Perhaps the fact that he had worked at Antioch, where the gospel had been preached by men of Cyprus and Cyrene (Acts 11:20), at Troas, where it had been preached by St. Luke (see Notes on 2Corinthians 2:12; Acts 16:8), to the Romans whom he found at Corinth, and who, like Aquila and Priscilla, had been already converted (see Notes on Acts 18:2), were thought to give a colour to the charge that he was boasting in other men's labours.

Having hope, when your faith is increased.--The verb is in the present tense, and should be translated, as your faith grows. The words are spoken in the spirit of one--

"Nil actum reputans si quid superesset agendum"

["Who thinks nought done while aught remains to do"]--

who seeks for fresh provinces to annex to the territory of his king. The growth of their faith will give him fresh courage, perhaps also fresh resources. But what does he mean by his "hope that we shall be enlarged according to" (or, perhaps, in relation to) "our rule"? The words seem to imply something more than a mere extension of labours, and suggest the probability that in his journey to Jerusalem, with the large and liberal gifts of the Gentile churches, he had an intention, here half-avowed, to endeavour to modify the terms of the concordat referred to in Galatians 2:9, and to get the sanction of the Church of Jerusalem for his mission work at Rome: though there the gospel had been preached by others, and it was, primarily, at least, one of the Churches of the Circumcision. It will be seen that this supposition explains better than any other the apologetic tone of Romans 15:20-29. It was his reluctance even to appear to build on another man's foundation that had hitherto kept him from them. He does not intend to appear, when he comes, in the character of the founder of this Church, or even as building the superstructure, but only as a friend, seeking mutual help and counsel. Spain is his goal. He takes Rome as a parenthesis. But he is going to Jerusalem, and he hopes that the difficulty which has hitherto hindered him will be removed.

Verse 15. - That is, of other men's labours. Not to thrust himself obtrusively into spheres of labour which legitimately belonged to others was a part of St. Paul's scrupulously chivalrous rule (2 Corinthians 3:10; Galatians 2:9; Romans 15:20). It contrasted with the usurping arrogance of these Jerusalem emissaries. When your faith is increased; rather, increases or grows. He delicately implies that their lack of faith prevents the extension of his labours. He could not leave in his rear an unstormed fortress of opposition to the gospel. The spread of the gospel depends on them. We shall be enlarged by you according to our rule abundantly. The Revised Version renders it more clearly, "We shall be magnified in you according to our province unto further abundance."

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.Not boasting of things without our measure,.... The apostle here asserts what he had done before, 2 Corinthians 10:13 with a view to explain it, as he does, saying,

that is of other men's labours; when they boasted of the Corinthians as their converts and children, whom they had begotten through the Gospel of Christ, they did not boast of other men's labours, as did the false apostles; who when they came to Corinth, found a church already planted by the apostle, and a multitude of believers, of whose conversion and faith he had been an instrument; and yet these men claimed them as their own, and an authority over them, when they were the fruit of the apostle's labours:

but having hope, when your faith is increased, that we shall be enlarged by you according to our rule abundantly; the sense is, that the apostle hoped, for he could not be sure, this lying in the secret will of God, that when the faith of the Corinthians was grown stronger, and more settled and established, and so would not stand in so much need of their care and instruction, they should be enlarged through their means; and that they should not stop here, but that the line, measure, or rule of their ministry, should be drawn to a greater length, and the bounds of it extended and carried abundantly further. The apostle intimates, that the weakness of their faith, and the disorders and divisions that were among them, were a hinderance to the spread of the Gospel; and that if their church state were in a better and a more settled condition, as it would give the apostles more leisure to preach the Gospel elsewhere, so it would serve to recommend it to other places beyond them; which would be an enlargement of the bounds of their ministry, and a means of magnifying of Christ and his Gospel, and of them also.
