"The person who sows sparingly will also reap sparingly and the person who sows generously will also reap generously.  Each person should do as he has decided- in his heart - not out of regret or out of necessity, for God loves a cheerful giver.  And God is able to make every grace overflow in you,  so that in every way, always having everything you need, you may excel in every good work. " 

2 Corinthians 9:6-8
