Applied economically this translates into the fact of a direct monetary gifting vehicle like a universal dividend being simultaneously able to increase individual aggregate demand without adding a cost to the system.  Likewise a discount to prices at retail to consumers where costs for any item or service are terminally summed, and reciprocally back to participating merchants  after the entire productive process itself ends, enables not only a systemic/macro-economic effect to prices but nullifies any possibility of injury to any economic agent as production has become consumption.

Grace is a traditionally religious simultaneous  unity of body, mind and spirit with God and/or with all aspects of oneself, and the concept of Grace applied economically and monetarily is direct, simultaneous, immediate and conclusive policy effect at all points of time (dividend) and the particular points of time (retail sale) where such policy can be applied with maximum effect (a general discount to prices).

Don’t ever let any religionist tell you that Grace is only transcendant….and don’t ever let any modernly habituated, overly scientistic types tell you that it is irrelevant.
