This chapter explains the indispensable role of divine grace, presenting it as the necessary counterpart to law. While law guides us, our wounded human nature requires God’s grace to be healed, elevated, and sustained on the path to our supernatural end. Grace is defined as a free, supernatural gift—a participation in the divine life itself—that perfects the soul’s essence and makes us capable of achieving a communion with God that is beyond our natural abilities. The chapter distinguishes between habitual (or sanctifying) grace, the stable quality that makes the soul holy, and actual grace, the divine assistance that moves us to do good in specific moments. This theological understanding is then contrasted with a powerful modern counterfeit: the promise of a technological “grace” that seeks not to heal sin, but to “fix” our biological finitude through enhancement, offering a salvation that is engineered and purchased, not freely given by God.
