2 Corinthians 9:6-7 Remember this: Whoever sows sparingly will also reap sparingly, and whoever sows generously will also reap generously. Each of you should give what you have decided in your heart to give, not reluctantly or under compulsion, for God loves a cheerful giver.
We find these verses amidst verses about service. Perhaps it is nestled here because God knew it was going to be harder for people to give their time than money. May I be willing to be generous with my time, not just my finances.
