2 Corinthians 9:6-8
6  But this I say: He who sows sparingly will also reap sparingly, and he who sows
bountifully will also reap bountifully.  7  So let each one give as he purposes in his
heart, not grudgingly or of  [ necessity; for God loves a cheerful giver.  8  And God is
able to make all grace abound toward you, that you, always having all sufficiency
in all things, may have an abound to every good work.
