2 Corinthians 9:7-9
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.
9:9 Just as it is written, “He has scattered widely, he has given to the poor; his righteousness remains forever.”
