2 Corinthians 9:6-8

9:6 My point is this: The person who sows sparingly will also reap sparingly, and the person who sows generously will also reap generously. 9:7 Each one of you should give just as he has decided in his heart, not reluctantly or under compulsion, because God loves a cheerful giver. 9:8 And God is able to make all grace overflow to you so that because you have enough of everything in every way at all times, you will overflow in every good work.
