Since then it is nothing else than a testament, the first and by far the best preparation for the mass is a hungry soul and a firm joyful faith of the heart accepting such a testament Who would not go with great and joyful desire, hope and comfort, and demand a thousand gulden, if he knew that at a certain place they had been bequeathed him; especially if there were no other condition than that he remember, honor, and praise the testator? So, in this matter, you must above all else take heed to your heart, that you believe the words of Christ, and admit their truth, when He says to you and to all: "This is My blood, a new testament, by which I bequeath you forgiveness of all sins and eternal life." How could you do Him greater dishonor and show greater disrespect to the holy mass than by not believing or by doubting? For He desired this to be so certain that He Himself even died for it. Surely such doubt would be naught else than denying and blaspheming Christ's sufferings and death, and every blessing which He has thereby obtained. 14. For this reason, I have said, everything depends upon the words of this sacrament, which are the words of Christ, and which we verily should set in pure gold and precious stones, and keep nothing more diligently before the eyes of the heart, that faith be exercised thereby. Let another pray, fast, go to confession, prepare himself for mass and the sacrament as he will. Do thou the same, but know that all that is pure fool's-work and self-deception, if you do not set before you the words of the testament and arouse yourself to believe and desire them. A long time would you have to polish your shoes, pick the lint[7] off your clothes, and deck yourself out to get an inheritance, if you had no letter and seal with which you could prove your right to it. But if you have letter and seal, and believe, desire, and seek it, it must be given you, even though you were scaly, scabby, stinking and most unclean. So if you would receive this sacrament and testament worthily, see to it that you bring forward these living words of Christ, rely thereon with a strong faith, and desire what Christ has therein promised you: then it will be given you, then are you worthy and well prepared. This faith and confidence must and will make you joyful, and awaken a bold love for Christ, by means of which you will begin with joy to lead a really good life and with all your heart to flee from sin. For he who loves Christ will surely do what pleases Him, and leave undone what does not please Him. But who will love Him except he taste the riches of this testament which Christ, out of pure mercy, has freely bequeathed to poor sinners? This taste comes by the faith which believes and trusts the testament and promise. If Abraham had not believed the promise of God he would never have amounted to anything. Just as certainly, then, as Abraham, Noah, and David accepted and believed their promises: so
