The Bible Says in 2 Corinthians 9:7-10

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.  

9 As it is written: 

“He has dispersed abroad,
He has given to the poor;
His righteousness endures forever.”

10 Now may He who supplies seed to the sower, and bread for food, supply and multiply the seed you have sown and increase the fruits of your righteousness,
