To make what we have said more easily understood, let us set it forth under a figure. The works of a Christian man, who is justified and saved by his faith out of the pure and unbought mercy of God, ought to be regarded in the same light as would have been those of Adam and Eve in paradise and of all their posterity if they had not sinned. Of them it is said, "The Lord God took the man and put him into the garden of Eden to dress it and to keep it" (Gen. ii. 15). Now Adam had been created by God just and righteous, so that he could not have needed to be justified and made righteous by keeping the garden and working in it; but, that he might not be unemployed, God gave him the business of keeping and cultivating paradise. These would have indeed been works of perfect freedom, being done for no object but that of pleasing God, and not in order to obtain justification, which he already had to the full, and which would have been innate in us all.
So it is with the works of a believer. Being by his faith replaced afresh in paradise and created anew, he does not need works for his justification, but that he may not be idle, but may exercise his own body and preserve it. His works are to be done freely, with the sole object of pleasing God. Only we are not yet fully created anew in perfect faith and love; these require to be increased, not, however, through works, but through themselves.
A bishop, when he consecrates a church, confirms children, or performs any other duty of his office, is not consecrated as bishop by these works; nay, unless he had been previously consecrated as bishop, not one of those works would have any validity; they would be foolish, childish, and ridiculous. Thus a Christian, being consecrated by his faith, does good works; but he is not by these works made a more sacred person, or more a Christian. That is the effect of faith alone; nay, unless he were previously a believer and a Christian, none of his works would have any value at all; they would really be impious and damnable sins.
True, then, are these two sayings: "Good works do not make a good man, but a good man does good works"; "Bad works do not make a bad man, but a bad man does bad works." Thus it is always necessary that the substance or person should be good before any good works can be done, and that good works should follow and proceed from a good person. As Christ says, "A good tree cannot bring forth evil fruit, neither can a corrupt tree bring forth good fruit" (Matt. vii. 18). Now it is clear that the fruit does not bear the tree, nor does the tree grow on the fruit; but, on the contrary, the trees bear the fruit, and the fruit grows on the trees.
As then trees must exist before their fruit, and as the fruit does not make the tree either good or bad, but on the contrary, a tree of either kind produces fruit of the same kind, so must first the person of the man be good or bad before he can do either a good or a bad work; and his works do not make him bad or good, but he himself makes his works either bad or good.
We may see the same thing in all handicrafts. A bad or good house does not make a bad or good builder, but a good or bad builder makes a good or bad house. And in general no work makes the workman such as it is itself; but the workman makes the work such as he is himself. Such is the case, too, with the works of men. Such as the man himself is, whether in faith or in unbelief, such is his work: good if it be done in faith; bad if in unbelief. But the converse is not true that, such as the work is, such the man becomes in faith or in unbelief. For as works do not make a believing man, so neither do they make a justified man; but faith, as it makes a man a believer and justified, so also it makes his works good.
Since then works justify no man, but a man must be justified before he can do any good work, it is most evident that it is faith alone which, by the mere mercy of God through Christ, and by means of His word, can worthily and sufficiently justify and save the person; and that a Christian man needs no work, no law, for his salvation; for by faith he is free from all law, and in perfect freedom does gratuitously all that he does, seeking nothing either of profit or of salvation—since by the grace of God he is already saved and rich in all things through his faith—but solely that which is well-pleasing to God.
So, too, no good work can profit an unbeliever to justification and salvation; and, on the other hand, no evil work makes him an evil and condemned person, but that unbelief, which makes the person and the tree bad, makes his works evil and condemned. Wherefore, when any man is made good or bad, this does not arise from his works, but from his faith or unbelief, as the wise man says, "The beginning of sin is to fall away from God"; that is, not to believe. Paul says, "He that cometh to God must believe" (Heb. xi. 6); and Christ says the same thing: "Either make the tree good and his fruit good; or else make the tree corrupt, and his fruit corrupt" (Matt. xii. 33),—as much as to say, He who wishes to have good fruit will begin with the tree, and plant a good one; even so he who wishes to do good works must begin, not by working, but by believing, since it is this which makes the person good. For nothing makes the person good but faith, nor bad but unbelief.
It is certainly true that, in the sight of men, a man becomes good or evil by his works; but here "becoming" means that it is thus shown and recognised who is good or evil, as Christ says, "By their fruits ye shall know them" (Matt. vii. 20). But all this stops at appearances and externals; and in this matter very many deceive themselves, when they presume to write and teach that we are to be justified by good works, and meanwhile make no mention even of faith, walking in their own ways, ever deceived and deceiving, going from bad to worse, blind leaders of the blind, wearying themselves with many works, and yet never attaining to true righteousness, of whom Paul says, "Having a form of godliness, but denying the power thereof, ever learning and never able to come to the knowledge of the truth" (2 Tim. iii. 5, 7).
He then who does not wish to go astray, with these blind ones, must look further than to the works of the law or the doctrine of works; nay, must turn away his sight from works, and look to the person, and to the manner in which it may be justified. Now it is justified and saved, not by works or laws, but by the word of God—that is, by the promise of His grace—so that the glory may be to the Divine majesty, which has saved us who believe, not by works of righteousness which we have done, but according to His mercy, by the word of His grace.
