Furthermore, no good work helps an unbeliever, so as to justify or save him. And, on the other hand, no evil work makes him wicked or damns him, but the unbelief which makes the person and the tree evil, does the evil and damnable works. Hence when a man is made good or evil, this is effected not by the works, but by faith or unbelief, as the Wise Man says, "This is the beginning of sin, that a man falls away from God," [Sirach 10:14 f.] which happens when he does not believe. And Paul, Hebrews xi, says, He that cometh to God must believe." [Heb. 11:6] And Christ says the same: "Either make the tree good and his fruit good; or else make the tree corrupt and his fruit corrupt," [Matt. 12:33] as if He would say, "Let him who would have good fruit begin by planting a good tree." So let him who would do good works not begin with the doing of works, but with believing, which makes the person good. For nothing makes a man good except faith, nor evil except unbelief.
It is indeed true that in the sight of men a man is made good or evil by his works, but this being made good or evil is no more than that he who is good or evil is pointed out and known as such; as Christ says, in Matthew vii, "By their fruits ye shall know them." [Matt. 7:20] But all this remains on the surface, and very many have been deceived by this outward appearance and have presumed to write and teach concerning good works by which we may be justified, without even mentioning faith; they go their way, always being deceived and deceiving, advancing, indeed, but into a worse state, blind leaders of the blind [2 Tim. 3:13], wearying themselves with many works, and yet never attaining to true righteousness [Matt. 15:14]. Of such Paul says, in II Timothy iii, "Having the form of godliness, but denying its power, always learning and never attaining to the knowledge of the truth." [2 Tim. 3:5, 7]
He, therefore, who does not wish to go astray with those blind men, must look beyond works, and laws and doctrines about works; nay, turning his eyes from works, he must look upon the person, and ask how that is justified. For the person is justified and saved not by works nor by laws, but by the Word of God, that is, by the promise of His grace [Tit. 3:5], and by faith, that the glory may remain God's, Who saved us not by works of righteousness which we have done, but according to His mercy by the word of His grace, when we believed. [1 Cor. 1:21]
[Sidenote: The Doctrine of Good Works]
From this it is easy to know in how far good works are to be rejected or not, and by what standard all the teachings of men concerning works are to be interpreted. If works are sought after as a means to righteousness, are burdened with this perverse leviathan[15] and are done under the false impression that through them you are justified, they are made necessary and freedom and faith are destroyed; and this addition to them makes them to be no longer good, but truly damnable works. For they are not free, and they blaspheme the grace of God, since to justify and to save by faith belongs to the grace of God alone. What the works have no power to do, they yet, by a godless presumption, through this folly of ours, pretend to do, and thus violently force themselves into the office and the glory of grace. We do not, therefore, reject good works; on the contrary, we cherish and teach them as much as possible. We do not condemn them for their own sake, but because of this godless addition to them and the perverse idea that righteousness is to be sought through them; for that makes them appear good outwardly, when in truth they are not good; they deceive men and lead men to deceive each other, like ravening wolves in sheep's clothing [Matt. 7:15].
But this leviathan and perverse notion concerning works is insuperable where sincere faith is wanting. Those work-saints cannot get rid of it unless faith, its destroyer, come and rule in their hearts. Nature of itself cannot drive it out, nor even recognize it, but rather regards it as a mark of the most holy will. And if the influence of custom be added and confirm this perverseness of nature, as wicked Magisters have caused it to do, it becomes an incurable evil, and leads astray and destroys countless men beyond all hope of restoration. Therefore, although it is good to preach and write about penitence, confession and satisfaction, if we stop with that and do not go on to teach about faith, our teaching is unquestionably deceitful and devilish.
[Sidenote: What we are to Preach]
Christ, like His forerunner John, not only said, "Repent ye," [Matt. 3:2] but added the word of faith, saying, "The kingdom of heaven is at hand." [Matt. 4:17] And we are not to preach only one of these words of God, but both; we are to bring forth out of our treasure things new and old [Matt. 13:52], the voice of the law as well as the word of grace. We must bring forth the voice of the law that men may be made to fear and to come to a knowledge of their sins, and so be converted to repentance and a better life. But we must not stop with that. For that would be only to wound and not to bind up, to smite and not to heal, to kill and not to make alive, to lead down into hell and not to bring back again, to humble and not to exalt. Therefore, we must also preach the word of grace and the promise of forgiveness, by which faith is taught and strengthened. Without this word of grace the works of the law, contrition, penitence and all the rest are performed and taught in vain.
There remain even to our day preachers of repentance and grace, but they do not so explain God's law and promise that a man might learn from them the source of repentance and grace. For repentance proceeds from the law of God, but faith or grace from the promise of God, as Romans x says, "Faith cometh by hearing, and hearing by the word of Christ" [Rom. 10:17]; so that a man is consoled and exalted by faith in the divine promise, after he has been humbled and led to a knowledge of himself by the threats and the fear of the divine law. So we read in Psalm xxx, "Weeping may endure for a night, but joy cometh in the morning." [Ps. 30:6]
