To be sure, the response of faith to revelation, which God grants to the creature he chooses and moves with his love, occurs in such a way that it is truly the creature that provides the response, with its own nature and its natural powers of love.

The line articulates a classic Catholic “both/and” account of grace and freedom: revelation and the act of faith are initiated by God’s gratuitous self-gift (“God grants… chooses and moves with his love”), yet the human response is not coerced or merely apparent. Faith is a genuinely human act—performed by the creature as creature—engaging the person’s created faculties, including the natural capacity to love. Balthasar’s emphasis guards against two distortions: a determinism that would make faith a divine act in us without our real participation, and a Pelagianism that would treat faith as a purely natural achievement. The significance lies in portraying grace as elevating and perfecting nature rather than replacing it.
