What does 2 Corinthians 9:10 mean?
Paul is urging the Corinthians to be generous in their giving to suffering Christians in Jerusalem. He has said they should give willingly and cheerfully a portion of what God has given to them. Scripture presents Christian giving as something done out of love, not legalism, obligation, or command. That theme continues here in Paul's comments to the church in Corinth.This makes an additional point, though: God is ultimately the one who gives. He is the one who provides both the seed for the bread and the bread itself. In other words, God makes the giver capable of giving. Paul adds that God will multiply the seed of those who give in order to increase the harvest of the righteousness that comes as a result. It's important to note that the increase is to the benefit of the one who receives—this is not a promise to financially prosper the giver.
Paul insists there is more to giving as a Christlike act of grace than just putting food in hungry bellies. The gift itself is a seed that will produce more and more righteousness. The one who gives shares the privilege of being used by God in this process.
