We do not then reject good works; nay, we embrace them and teach them in the highest degree. It is not on their own account that we condemn them, but on account of this impious addition to them and the perverse notion of seeking justification by them. These things cause them to be only good in outward show, but in reality not good, since by them men are deceived and deceive others, like ravening wolves in sheep's clothing.
Now this leviathan, this perverted notion about works, is invincible when sincere faith is wanting. For those sanctified doers of works cannot but hold it till faith, which destroys it, comes and reigns in the heart. Nature cannot expel it by her own power; nay, cannot even see it for what it is, but considers it as a most holy will. And when custom steps in besides, and strengthens this pravity of nature, as has happened by means of impious teachers, then the evil is incurable, and leads astray multitudes to irreparable ruin. Therefore, though it is good to preach and write about penitence, confession, and satisfaction, yet if we stop there, and do not go on to teach faith, such teaching is without doubt deceitful and devilish. For Christ, speaking by His servant John, not only said, "Repent ye," but added, "for the kingdom of heaven is at hand" (Matt. iii. 2).
For not one word of God only, but both, should be preached; new and old things should be brought out of the treasury, as well the voice of the law as the word of grace. The voice of the law should be brought forward, that men may be terrified and brought to a knowledge of their sins, and thence be converted to penitence and to a better manner of life. But we must not stop here; that would be to wound only and not to bind up, to strike and not to heal, to kill and not to make alive, to bring down to hell and not to bring back, to humble and not to exalt. Therefore the word of grace and of the promised remission of sin must also be preached, in order to teach and set up faith, since without that word contrition, penitence, and all other duties, are performed and taught in vain.
There still remain, it is true, preachers of repentance and grace, but they do not explain the law and the promises of God to such an end, and in such a spirit, that men may learn whence repentance and grace are to come. For repentance comes from the law of God, but faith or grace from the promises of God, as it is said, "Faith cometh by hearing, and hearing by the word of God" (Rom. x. 17), whence it comes that a man, when humbled and brought to the knowledge of himself by the threatenings and terrors of the law, is consoled and raised up by faith in the Divine promise. Thus "weeping may endure for a night, but joy cometh in the morning" (Psalm xxx. 5). Thus much we say concerning works in general, and also concerning those which the Christian practises with regard to his own body.
Lastly, we will speak also of those works which he performs towards his neighbour. For man does not live for himself alone in this mortal body, in order to work on its account, but also for all men on earth; nay, he lives only for others, and not for himself. For it is to this end that he brings his own body into subjection, that he may be able to serve others more sincerely and more freely, as Paul says, "None of us liveth to himself, and no man dieth to himself. For whether we live, we live unto the Lord; and whether we die, we die unto the Lord" (Rom. xiv. 7, 8).
Thus it is impossible that he should take his ease in this life, and not work for the good of his neighbours, since he must needs speak, act, and converse among men, just as Christ was made in the likeness of men and found in fashion as a man, and had His conversation among men.
Yet a Christian has need of none of these things for justification and salvation, but in all his works he ought to entertain this view and look only to this object--that he may serve and be useful to others in all that he does; having nothing before his eyes but the necessities and the advantage of his neighbour. Thus the Apostle commands us to work with our own hands, that we may have to give to those that need. He might have said, that we may support ourselves; but he tells us to give to those that need. It is the part of a Christian to take care of his own body for the very purpose that, by its soundness and well-being, he may be enabled to labour, and to acquire and preserve property, for the aid of those who are in want, that thus the stronger member may serve the weaker member, and we may be children of God, thoughtful and busy one for another, bearing one another's burdens, and so fulfilling the law of Christ.
Here is the truly Christian life, here is faith really working by love, when a man applies himself with joy and love to the works of that freest servitude in which he serves others voluntarily and for nought, himself abundantly satisfied in the fulness and riches of his own faith.
Thus, when Paul had taught the Philippians how they had been made rich by that faith in Christ in which they had obtained all things, he teaches them further in these words: "If there be therefore any consolation in Christ, if any comfort of love, if any fellowship of the Spirit, if any bowels and mercies, fulfil ye my joy, that ye be like-minded, having the same love, being of one accord, of one mind. Let nothing be done through strife or vainglory; but in lowliness of mind let each esteem other better than themselves. Look not every man on his own things, but every man also on the things of others" (Phil. ii. 1-4).
In this we see clearly that the Apostle lays down this rule for a Christian life: that all our works should be directed to the advantage of others, since every Christian has such abundance through his faith that all his other works and his whole life remain over and above wherewith to serve and benefit his neighbour of spontaneous goodwill.
