Then, too, I have never forced or begged any one to hear me, or to read my sermons. I have freely ministered in the Church of that which God has given me and which I owe the Church. Whoever likes it not, may hear and read what others have to say. And if they are not willing to be my debtors, it matters little. For me it is enough, and even more than too much, that some laymen condescend to read what I say. Even though there were nothing else to urge me, it should be more than sufficient that I have learned that your princely Grace is pleased with such German books and is eager to receive instruction in Good Works and the Faith, with which instruction it was my duty, humbly and with all diligence to serve you. Therefore, in dutiful humility I pray that your princely Grace may accept this offering of mine with a gracious mind, until, if God grant me time, I prepare a German exposition of the Faith in its entirety. For at this time I have wished to show how in all good works we should practice and make use of faith, and let faith be the chief work. If God permit, I will treat at another time of the Faith[5] itself—how we are daily to pray or recite it. I humbly commend myself herewith to your princely Grace,     Your Princely Grace's         Humble Chaplain,             Dr. Martin Luther. From Wittenberg, March 39th, A.D. 1520. THE TREATISE [Sidenote: Faith and the Commandments] I. We ought first to know that there are no good works except those which God has commanded, even as there is no sin except that which God has forbidden. Therefore whoever wishes to know and to do good works needs nothing else than to know God's commandments. Thus Christ says, Matthew xix, "If thou wilt enter into life, keep the commandments." [Matt. 19:17] And when the young man asks Him, Matthew xix, what he shall do that he may inherit eternal life, Christ sets before him naught else but the Ten Commandments. [Matt. 19:18 f.] Accordingly, we must learn how to distinguish among good works from the Commandments of God, and not from the appearance, the magnitude, or the number of the works themselves, nor from the judgment of men or of human law or custom, as we see has been done and still is done, because we are blind and despise the divine Commandments. [Sidenote: Faith the Best Work] II. The first and highest, the most precious of all good works is faith in Christ, as He says, John vi. When the Jews asked Him: "What shall we do that we may work the works of God?" He answered: "This is the work of God, that ye believe on Him Whom He hath sent." [John 6:28 f.] When we hear or preach this word, we hasten over it and deem it a very little thing and easy to do, whereas we ought here to pause a long time and to ponder it well. For in this work[6] all good works must be done and receive from it the inflow of their goodness, like a loan. This we must put bluntly, that men may understand it.
