“A man is generous because he trusts God and never doubts that he will always have enough. In contrast, a man is covetous and anxious because he does not trust God. Now faith is the master workman and the motivating force behind the good works of generosity, just as it is in all the other commandments. Without this faith, generosity is of no use at all, it is just a careless squandering of money.”
