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 abundance for every good work. 

—  2 Corinthians 9:6-8 NKJV
