"The sower seems to spend and scatter his seed. The giver of alms also seems to scatter his goods. Yet this deed bears fruit, and bears it more surely than sowing. From sowing there is not always a harvest, but from the sowing of alms there is never crop failure.
"Only goodwill must be placed into it. This disposition is like rain falling in due season upon the sowing. Let each give as much as his heart is disposed to give. Whatever is not according to this measure will be fruitless.
"Not out of grief or necessity. By grief is meant regret over what is given, which is a sign of stinginess. By necessity is meant compulsion, whether from the need to obey or from the common nature of the work.
"The Apostle wants giving to proceed from the heart, like lush grass from rich soil."
According to St. John Chrysostom, "many fear to give alms on the pretext that they themselves may become poor and have to beg alms from others. To dispel this fear, the Apostle entreats God that every grace may abound. He asks God for them neither riches nor excess, but every sufficiency. In spiritual goods, however, he asks abundance for them.
"Time will end, but the fruits of beneficence will remain, and in due season they will be reaped by the benefactor. The Apostle brings in the prophet as counselor (Ps 111:9), finding a testimony that urges generosity. For the word 'he has scattered' means nothing other than generosity in giving. And although what was given is no longer present, the fruits of giving remain forever.
"But even in this age the same prophet gives assurance: I have not seen such a righteous benefactor forsaken, and his seed shall be in blessing" (Ps 36:25-26).
Then, in his prayer, the Apostle asks God that the Corinthians, having received seed for the sowing of alms, may truly use it for this purpose. In this way they would be enriched with the fruits of righteousness. The Apostle desires that their material sufficiency should go together with spiritual progress (Theophan).
In verse 11, according to the explanation of Blessed Theophylact, the Apostle teaches how wealth must be used. "It must not be buried in the ground, but possessed in all simplicity, that is, given away with every generosity." By simplicity here he means generosity, from which almsgiving comes, and which gives occasion for great thanksgiving (Chrysostom).
