Why is miserliness such a sin, and generosity such a virtue? Sirach explains it in terms of the miser being turned in upon himself. “Greed will shrivel up a person’s soul.” I might say that generosity is a sign of being like God, who is endlessly, recklessly generous.
So - enjoy life, don’t waste a day. It is going to end, after all. That’s not a sad thought - as old leaves wither and fall off the tree. new ones unfold. It’s all part of a greater plan.
And where do you fit in to this greater plan? Well, to get an answer to that, you need to spend much time camping out at Wisdom’s house.
