The Bible says so

Give

All areas of service of the community are carried out through voluntary donations of caring people. The most important thing is not the size of the donation, but the attitude and condition of the heart. God sees our needs and seeks to deprive us of our worries. He also wants to see the love and sacrifice of our grateful hearts. «Every man according as he purposeth in his heart, so let him give; not grudgingly, or of necessity: for God loveth a cheerful giver!» (2 Cor. 9:7).
