14 But by an equality, that now at this time your abundance may be a supply for their want, that their abundance also may be a supply for your want: that there may be equality:
Of this same thing also in the second Epistle to the Corinthians: "Let your abundance supply their want, that their abundance also may be the supplement of your want, that there may be equality: as it is written, He who had much had not excess; and he who had little had no lack."
The equality Paul is speaking of consists in the fact that because they are ministering to the saints this time they will be repaid by them in the future, for they are making the saints their debtors.
For not only by the words he has before used but by these also, he is desirous of making the commandment light. Nor yet from this consideration alone, but from that of the recompense also, again he maketh it easier; and uttereth higher things than they deserve, saying, "That there may be equality at this time, and their abundance" a supply "for your want." Now what is it that he saith? 'Ye are flourishing in money; they in life and in boldness towards God.' 'Give ye to them, therefore, of the money which ye abound in but they have not; that ye may receive of that boldness wherein they are rich and ye are lacking.' See how he hath covertly prepared for their giving beyond their power and of their want. 'For,' he saith, 'if thou desirest to receive of their abundance, give of thine abundance; but if to win for thyself the whole, thou wilt give of thy want and beyond thy power.' He doth not say this, however, but leaves it to the reasoning of his hearers; and himself meanwhile works out his object and the exhortation that was meet, adding in keeping with what appeared, the words, that "there may be equality at this time." How equality? You and they mutually giving your superabundance, and filling up your wants. And what sort of equality is this, giving spiritual things for carnal? for great is the advantage on that side; how then doth he call it "equality?" either in respect of each abounding and wanting, doth he say that this [equality] takes place; or else in respect of the present life only. And therefore after saying "equality," he added, "at this time." Now this he said, both to subdue the high-mindedness of the rich, and to show that after our departure hence the spiritual possess the greater advantage. For here indeed we all enjoy much equality of honor; but then there will be a wide distinction and a very great superiority, when the just shine brighter than the sun.
