15 Not boasting of things 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,
The primacy of knowledge the apostle shows to those capable of reflection, in writing to those Greeks of Corinth, in the following terms: "But having hope, when your faith is increased, that we shall he magnified in you according to our rule abundantly, to preach the Gospel beyond you."
Someone who takes pride in his own work is not being excessively proud of himself. A prudent man does not rely on the labors of others. This is why Paul does not claim any credit for those who have come to faith by the preaching of other evangelists.
"Not glorying beyond" our "measure," that is, "in other men's labors, but having hope that as your faith grows, we shall be magnified in you according to our province unto further abundance, so as to preach the Gospel even unto the parts beyond you, and not to glory in another's province in regard of things ready to our hand."
He sets forth a large accusation of them on these grounds, both that they boasted of things without their measure, and of other men's labors; and that while the whole of the toil was the Apostles', they plumed themselves upon their labors. 'But we,' says he, 'showed these things in our deeds. We will not imitate those men therefore, but will say such things where our deeds bear us witness. And why,' says he, 'do I say, you?' "for I have hope that as your faith grows;" for he does not assert absolutely, preserving his own character, but, 'I hope,' he says, 'if you make progress, that our province will be extended even farther, "to preach the Gospel in the regions beyond." For we shall advance farther yet,' he says, 'so as to preach and labor, not so as to boast in words of what other men have labored.' And well did he call it "province and measure," as though he had come into possession of the world, and a rich inheritance; and showing that the whole was wholly God's. 'Having then such works,' he says, 'and expecting greater, we do not boast as they do who have nothing, nor do we ascribe any part to ourselves, but the whole to God.
