Sacrifice and blessing 'beyond all calculation'

I’m still reading Preaching the Luminous Word, a collection of sermons and essays by Ellen F. Davis. Here’s a good quotation to ponder during Lent: “‘Sacrifice’ and ‘restraint’ are dirty words in a culture committed to ever-more aggressive and rapacious economic strategies,” she writes. “This we know for sure: where true sacrifice is offered -- when human life is made holy, at some cost to ourselves, there God creates abundance, giving life and more life, against the odds and beyond all calculation.”
