We find many who pray, fast, establish endowments, do this or that, lead a good life before men, and yet if you should ask them whether they are sure that what they do pleases God, they say, "No"; they do not know, or they doubt. And there are some very learned men, who mislead them, and say that it is not necessary to be sure of this; and yet, on the other hand, these same men do nothing else but teach good works. Now all these works are done outside of faith, therefore they are nothing and altogether dead. For as their conscience stands toward God and as it believes, so also are the works which grow out of it. Now they have no faith, no good conscience toward God.
Therefore the works lack their head, and all their life and goodness is nothing. Hence it comes that when I exalt faith and reject such works done without faith, they accuse me of forbidding good works, when in truth I am trying hard to teach real good works of faith.
