2 Corinthians 9:6–7 (ESV) … “The point is this: whoever sows sparingly will also reap sparingly, and whoever sows bountifully will also reap bountifully. Each one must give as he has decided in his heart, not reluctantly or under compulsion, for God loves a cheerful giver.”
Having endorsed Titus and two other men (8:16–24), Paul returns to the subject of the collection for the church in Jerusalem. Paul explains that he is sending Titus and the others so that the Corinthians’ contribution can be ready when he visits. He points out that he has boasted about their willingness to help, and that he, along with the Corinthians themselves, would be embarrassed if he arrived with the Macedonians and found them unprepared (vv. 1–5). Paul encourages the Corinthians to give generously by arguing that God loves a cheerful giver (vv. 6–11). Their generosity would not only supply the needs of those in Jerusalem, it would also serve as an expression of thanksgiving to God and unite Jewish and Gentile believers (vv. 12–15).
Paul used a similar analogy in Galatians 6:7, 9. This analogy encouraged generous giving. Just as farmers should not expect a large harvest unless they sow generously, so Christians should not expect many blessings from God unless they bless others in a generous way.
