And whether that be done through a grace efficacious of itself, that is to say, through a divine inward motion which wholly determines our will to the good that it does; or whether there be only a sufficient grace, but such as does not fail to attain its end, and to become efficacious in the inward and outward circumstances wherein the man is and has been placed by God: one must return to the same conclusion that God is the final reason of salvation, of grace, of faith and of election in Jesus Christ.
