"[Good works] are necessary, neither to acquire salvation (as a means), nor to earn salvation (as a merit), nor to obtain salvation (as an indispensable condition or cause), nor to reach it (as a mode of coming to a final goal), nor finally, to preserve it (as a conserving cause). But we hold good works to be necessary, by the necessity, 1) of the divine command, Mal. 1: 6; Matt, 5: 44; 2) of our duty, or of gratitude due for the benefits of creation, redemption, etc.: 3) of presence, that believers may not lose the grace of God and faith, and fall from the hope of the inheritance; 4) of a divinely appointed order and sequence to justification and faith, because as effects they necessarily follow their cause.”
