Each one must do just as he has purposed in his heart, not grudgingly or under compulsion, for God loves a cheerful giver. And God is able to make all grace abound to you, so that always having all sufficiency in everything, you may have an abundance for every good deed; as it is written, "HE SCATTERED ABROAD, HE GAVE TO THE POOR, HIS RIGHTEOUSNESS ENDURES FOREVER." Now He who supplies seed to the sower and bread for food will supply and multiply your seed for sowing and increase the harvest of your righteousness; you will be enriched in everything for all liberality, which through us is producing thanksgiving to God.
(2 Corinthians 9:7-11)
