2 Corinthians 9:7-11

Let each man do according as he hath purposed in his heart: not grudgingly, or of necessity: for God loveth a cheerful giver. And God is able to make all grace abound unto you; that ye, having always all sufficiency in everything, may abound unto every good work: as it is written, He hath scattered abroad, he hath given to the poor; His righteousness abideth for ever. And he that supplieth seed to the sower and bread for food, shall supply and multiply your seed for sowing, and increase the fruits of your righteousness: ye being enriched in everything unto all liberality, which worketh through us thanksgiving to God.
