2 Corinthians 9:10

Herein one may particularly admire the wisdom of Paul, that after having exhorted from spiritual considerations and from temporal, in respect of the recompense also he again does the very same, making the returns he mentions of either kind. This, (for instance,) "He hath scattered abroad, he hath given to the poor, his righteousness abideth for ever," belongs to a spiritual return; that again, "multiply your seed for sowing," to a temporal recompense. Still, however, he rests not here, but even again passes back to what is spiritual, placing the two continually side by side; for "increase the fruits of your righteousness," is spiritual. This he does, and gives variety by it to his discourse, tearing up by the roots those their unmanly and faint-hearted reasonings, and using many arguments to dissipate their fear of poverty, as also the example which he now brings. For if even to those that sow the earth God gives, if to those that feed the body He grants abundance; much more will He to those who till the soil of heaven, to those who take care for the soul; for these things He willeth should yet more enjoy His providing care. However, he does not state this in the way of inference nor in the manner I have done, but in the form of a prayer; thus at once making the reference plain, and the rather leading them on to hope, not only from what [commonly] takes place, but also from his own prayer: for, 'May He minister,' saith he, 'and multiply your seed for sowing, and increase the fruits of your righteousness.' Here also again he hints, in an unsuspicious way, at largeness [in giving], for the words, "multiply and increase," are by way of indicating this; and at the same time he allows them to seek for nothing more than necessaries, saying, "bread for food." For this also is particularly worthy of admiration in him, (and it is a point he successfully established even before,) namely, that in things which be necessary, he allows them to seek for nothing more than need requires; but in spiritual things counsels them to get for themselves a large superabundance. Wherefore he said above also, "that having a sufficiency ye may abound to every good work:" and here, "He that ministereth bread for food, multiply your seed for sowing;" that is to say, the spiritual [seed]. For he asks not almsgiving merely, but with largeness. Wherefore also he continually calls it "seed." For like as the corn cast into the ground showeth luxuriant crops, so also many are the handfuls almsgiving produceth of righteousness, and unspeakable the fruits it showeth.
