He who supplies seed to the sower and bread for food will supply and multiply the seed sown by the generous Corinthians (that they may ever be in a position to be generous), and will cause also the fruits of their righteousness to grow. Their righteousness, as it figures in this last phrase, is of course represented, for the time being, by their generosity; and the poetic expression "fruits of righteousness," which is borrowed from Hosea, designates the results which that generosity produces. It is not only an investment which guarantees to them the generous care of God for their own welfare; it is a seed which bears another and more spiritual harvest. With some expansion of heart on this the Apostle concludes. (_a_) It yields a rich harvest of thanksgiving to God. This is expressed in ver. 12, and is the principal point. It is something to fill up further the measure of a brother's needs by a timely gift, but how much more it is to change the tune of his spirit, and whereas we found him cheerless or weak in faith, to leave him gratefully praising God. True thankfulness to the Heavenly Father is an atmosphere in which all virtues flourish: and those whose charity bears fruit in this grateful spirit are benefactors of mankind to an extent which no money can estimate. It is probably forcing the Apostle's language to insist that λειτουργία, as a name for the collection, has any priestly or sacrificial reference;[79] but unfeigned charity is in its very nature a sacrifice of praise to God--the answer of our love to His; and it has its best effect when it evokes the thanksgivings to God of those who receive it. Wherever love is, He must be first and last.
