 Explaining the efficacy of grace is easier on Estius’s theory than on the competing theories, because it is simpler. On the competing theories, which include Jansen’s, the efficacy of actual grace of the will depends on a connection of some sort, within the mind of a creature, between a created grace, like Jansen’s “victorious pleasure,” and a meritorious choice. Estius’s theory is simpler: The efficacy of actual grace is a direct consequence of the general principle that God’s absolute will is infallibly realized.
