Every man according as he purposeth in his heart, so let him give; not grudgingly, or of necessity: for God loveth a cheerful giver.
According as he purposeth in his heart - the consent of the free choice [proairesis] must accompany the gift. Opposed to "of necessity;" as "grudgingly" is to "a cheerful giver" (Proverbs 22:9; Proverbs 11:25; Isaiah 32:8).
