(15) And I will very gladly spend and be spent.--The pronoun is emphatic, I, for my part. The latter verb implies spending to the last farthing. As he sought not theirs, but them, so he is ready to spend for them not only all that he has, but even, as if to the verge of exhaustion, all that he is. And yet with all this there was the painful consciousness of toiling without adequate return. It seemed to him, in his intense craving for affection, as if their love varied inversely with his own.

Verse 15. - Spend and be spent; rather, spend and be outspent, or spent to the uttermost (Philippians 2:17).

12:11-21 We owe it to good men, to stand up in the defence of their reputation; and we are under special obligations to those from whom we have received benefit, especially spiritual benefit, to own them as instruments in God's hand of good to us. Here is an account of the apostle's behaviour and kind intentions; in which see the character of a faithful minister of the gospel. This was his great aim and design, to do good. Here are noticed several sins commonly found among professors of religion. Falls and misdeeds are humbling to a minister; and God sometimes takes this way to humble those who might be tempted to be lifted up. These vast verses show to what excesses the false teachers had drawn aside their deluded followers. How grievous it is that such evils should be found among professors of the gospel! Yet thus it is, and has been too often, and it was so even in the days of the apostles.And I will gladly spend,.... Meaning all his time, talents, and strength, which God had bestowed upon him for their spiritual profit and advantage; yea, all that small pittance of worldly goods that he enjoyed: he not only determined to take nothing from them, but was willing to communicate his little substance to them, or spend it in their service; and not only so, but be spent for them:

and be spent for you, or "for your souls": for the good of them; his sense is, either that he was willing to have his whole substance expended, if it would be of any use to them; or his whole strength exhausted, in laborious preaching to them; or even his life to be laid down for them, was it necessary; which sense is favoured by the Syriac and Arabic versions; all which expressed his tender affection as a spiritual father for them: adding,

though the more abundantly I love you, the less I be loved; though he loved them more than he did other churches, or than the false apostles loved them, and yet were loved by them less than he was by other churches; or by them, than the false apostles were; or rather the meaning is, that though he increased in his love, and in the expressions of it to them, and they grew colder and more indifferent to him, yet this should not hinder his warmest desires and most earnest endeavours after their spiritual and eternal welfare. This way of speaking strongly expresses his love to them, and tacitly implies the lukewarmness of theirs to him; and yet that it should be no discouragement to him to proceed in doing them all the service he was capable of.
