The hall is a place to wait in, a place from which to try the various doors, not a place to live in. For that purpose the worst of the rooms (whichever that may be) is, I think, preferable. It is true that some people may find they have to wait in the hall for a considerable time, while others feel certain almost at once which door they must knock at. I do not know why there is this difference, but I am sure God keeps no one waiting unless He sees that it is good for him to wait. When you do get into your room you will find that the long wait has done you some kind of good which you would not have had otherwise. But you must regard it as waiting, not as camping. You must keep on praying for light; and, of course, even in the hall, you must begin trying to obey the rules which are common to the whole house. And above all you must be asking which door is the true one; not which pleases you best by its paint and panelling. In plain language, the question should never be: 'Do I like that kind of service?' but 'Are these doctrines true: is holiness here? Does my conscience move me towards this? Is my reluctance to knock at this door due to my pride, or my mere taste, or my personal dislike of this particular door-keeper?'When you have reached your own room, be kind to those who have chosen different doors and to those who are still in the hall. If they are wrong they need your prayers all the more; and if there are your enemies, then you are under orders to pray for them. That is one of the rules common to the whole house.
You are a hater of activity in life; quite right, for before there can be any meaning in activity, life must have continuity, and this your life lacks. You occupy yourself with your studies, that is true, you are even industrious. But it is only for your own sake and is done with as little teleology as possible. Otherwise you are unoccupied; like those workers in the Gospel, you stand idle in the marketplace (Matthew 20:3). You stick your hands in your pockets and observe life. Then you rest in despair, nothing occupies you, you don’t step aside for anything: “if someone were to throw a tile down from the roof I wouldn’t get out of the way.” You are like someone dying, you die daily, not in the profound, serious sense in which one usually takes that word, but life has lost its reality and “you always reckon your lifetime from one day’s notice to quit to the next”. You let everything pass you by, it makes no impression, but then suddenly something comes which grips you, an idea, a situation, a smile from a young girl, and then you are “in touch”; for just as on some occasions you are not in touch, so at others you are in touch and of service in every way. Wherever something is going on you are “in touch”. You conduct your life as it is your custom to behave in a crowd, you “work your way into the thickest of it, trying if possible to be forced up above the others so as to be able to lie on top of them”; if you manage to get up there you “make yourself as comfortable as possible”, and this is also the way you let yourself be carried along through life. But when the crowd disperses, when the event is over, you stand once more at the street corner and look at the world. A dying person possesses, as you know, a supernatural energy, and so too with you. If there is an idea to be thought through, a work to be read through, a plan to be carried out, a little adventure to be experienced - yes, a hat to be bought, you take hold of the matter with an immense energy. According to circumstance, you work on untiringly for a day, for a month; you are happy in the assurance that you still have the same abundance of strength as before, you take no rest, “no Satan can keep up with you”. If you work together with others, you work them into the ground. But then when the month or, what you always consider the maximum, the six months have gone, you break off and say, “and that’s the end of the story”. You retire and leave it all to the other party, or if you have been working alone you talk to no one about what you were doing. You then pretend to yourself and others that you have lost the desire and flatter yourself with the vain thought that you could have kept working with the same intensity if that is what you desired. But that is an immense deception. You would have succeeded in finishing it, as most others, if you had patiently willed it so, but you would have found out at the same time that it needs a kind of perseverance quite different from yours.
Manifest in this trade (commercial sale of indulgences via bankers) at the same time was a pernicious tendency in the Roman Catholic system, for the trade in indulgences was not an excess or an abuse but the direct consequence of the nomistic degradation of the gospel. That the Reformation started with Luther’s protest against this traffic in indulgences proves its religious origin and evangelical character. At issue here was nothing less than the essential character of the gospel, the core of Christianity, the nature of true piety. And Luther was the man who, guided by experience in the life of his own soul, again made people understand the original and true meaning of the gospel of Christ. Like the “righteousness of God,” so the term “penitence” had been for him one of the most bitter words of Holy Scripture. But when from Romans 1:17 he learned to know a “righteousness by faith,” he also learned “the true manner of penitence.” He then understood that the repentance demanded in Matthew 4:17 had nothing to do with the works of satisfaction required in the Roman institution of confession, but consisted in “a change of mind in true interior contrition” and with all its benefits was itself a fruit of grace. In the first seven of his ninety-five theses and further in his sermon on “Indulgences and Grace” (February 1518), the sermon on “Penitence” (March 1518), and the sermon on the “Sacrament of Penance” (1519), he set forth this meaning of repentance or conversion and developed the glorious thought that the most important part of penitence consists not in private confession (which cannot be found in Scripture) nor in satisfaction (for God forgives sins freely) but in true sorrow over sin, in a solemn resolve to bear the cross of Christ, in a new life, and in the word of absolution, that is, the word of the grace of God in Christ. The penitent arrives at forgiveness of sins, not by making amends (satisfaction) and priestly absolution, but by trusting the word of God, by believing in God’s grace. It is not the sacrament but faith that justifies. In that way Luther came to again put sin and grace in the center of the Christian doctrine of salvation. The forgiveness of sins, that is, justification, does not depend on repentance, which always remains incomplete, but rests in God’s promise and becomes ours by faith alone.
