2 Corinthians 9:7

Let each man do according as he hath purposed in his heart: not grudgingly [literally, of sorrow], or of necessity: for God loveth a cheerful giver. [Let each man give as his own heart prompts him and not as improperly influenced by others. Let no one give as if half crying to part with his money, and let no one feel constrained to give from any motives of necessity, such as popular applause, or to keep up with his neighbors, or to be rid of the solicitations of some urgent collector. Such giving is valueless in the sight of God, who values gifts only as they are really and truly such, and in no way extortions. The spirit of extortion is sorrow, but that of giving is cheerfulness.]
