Martin Luther

The Lightning

Luther never planned to be a monk. His father, a mining contractor in Mansfeld, had spent every spare florin getting his son into the law school at Erfurt. Martin was the future judge, the family's leverage out of the working class. Then, in July 1505, on a road outside Stotternheim, a thunderstorm broke over a twenty-one-year-old law student walking home. A bolt struck the ground near him. He fell in terror and cried, Help me, Saint Anne, and I will become a monk!

Two weeks later he kept the vow. He walked into the Augustinian Order of Hermits at Erfurt, his father raging at him, his life path detonated by a single instant of fear.

The vow itself tells you everything you need to know about late-medieval religion. A man who is suddenly aware of God's judgment does not run toward God. He runs toward the safest hiding place a sinner can find under the system he has inherited — and in 1505 that was the cloister. Behind walls. Under a discipline. Inside a community of professional pleaders. The monastery was not where you went because you loved God. It was where you went because you were terrified of Him and hoped that more religion might placate Him.

The Monk Who Could Not Be Forgiven

Luther was, by every account including his own, a model monk. He kept the rule with such ferocity that his abbot worried for his sanity. He fasted for three-day stretches. He went without sleep. He confessed for six hours at a time, exhausting his confessor by recounting every venial fault he could remember. He once recalled a sin halfway through a meal, ran from the refectory back to the confessional, and unburdened himself again.

And nothing helped. The system promised peace through penance, indulgence, sacrament, vow. Luther did all of it and grew more terrified. He understood, with a clarity most of his fellow monks did not, that the deal was rigged: a holy God demands perfect righteousness, and the harder you tried to produce it the more clearly you saw that you could not.

His confessor, Johann von Staupitz — a wise and patient man — finally said two things that began the long thaw in Luther's soul. First, he told Luther to stop confessing trifles and to look at his real problem, which was not particular sins but the orientation of his nature against God. Second, he told Luther to study Scripture and prepare to teach it. Specifically, he assigned Luther the chair of Bible at the new university in Wittenberg.

It was the kindest, most strategic command in church history. It put a desperate, exegetically gifted man in front of the actual text day after day, with no escape from its sentences.

The Phrase He Hated

Luther began lecturing on the Psalms in 1513. By 1515 he was lecturing on Romans. And it was here, in a tower study in the Augustinian cloister at Wittenberg — the precise location is debated, but Luther himself called it “the tower” — that the verse came at him.

“For in the gospel the righteousness of God is revealed — a righteousness that is by faith from first to last, just as it is written: ‘The righteous will live by faith.’”

ROMANS 1:17

Luther later wrote about his hatred of this verse with disarming honesty. I hated that word, “the righteousness of God,” by which I had been taught according to the custom and use of all teachers — that God is righteous and punishes the unrighteous sinner. Though I lived as a monk without reproach, I felt that I was a sinner before God with an extremely disturbed conscience. I could not believe that He was placated by my satisfaction. I did not love, yes, I hated the righteous God who punishes sinners.

This is not the language of a careful theologian. This is the language of a man bleeding internally from the conviction that the God he served was the God who would damn him. The phrase “righteousness of God” was, in his ears, a guillotine. Whatever iustitia Dei meant, it meant something he could not produce.

The Tower

And then the meaning shifted. Luther describes the moment as a kind of breaking through. He had been worrying the verse like a dog with a bone, holding the words in his mouth for months. And one day in the tower the connection between “the righteousness of God” and “by faith” finally clicked into place.

I began to understand that the righteousness of God is that by which the righteous lives by a gift of God, namely by faith. And this is the meaning: the righteousness of God is revealed by the gospel, namely, the passive righteousness with which the merciful God justifies us by faith, as it is written, “The righteous shall live by faith.” Here I felt that I was altogether born again and had entered paradise itself through open gates.

The phrase had not changed. The Bible had not changed. What changed was that Luther suddenly saw what every reader of Romans is supposed to see and what fallen religion will always misread: the righteousness of God in the gospel is not a righteousness God demands from us. It is a righteousness God gives to us.

The verb tense matters. Iustitia passiva, Luther called it — passive righteousness. Not something I produce. Something done to me. The same kind of thing as a body being healed by a physician. The patient does not heal himself. He receives the healing. The righteousness of God is not the impossible standard for which I was always going to fail; it is the gift of God's own righteousness reckoned to me through faith — and even the faith, as Paul will say in Ephesians 2, is itself a gift.

What the Reformation Was Actually About

What followed in church history — the Ninety-Five Theses two years later, the Diet of Worms in 1521, the splitting of Christendom — was not, at root, about indulgences. Indulgences were the spark. The fuel was Luther's tower experience. Once he had seen that justification was God's gift to be received and not man's achievement to be earned, the entire late-medieval architecture of merit, treasury, satisfaction, and meritorious works lost its ground.

And — this is the part Protestants who hate Reformed theology often miss — once you have seen that justification is God's gift, you cannot stop the dominoes from falling all the way down. If the righteousness is His gift, the faith that receives it is His gift. If the faith is His gift, the new heart that produces faith is His gift. If the new heart is His gift, the calling that births the new heart is His gift. If the calling is His gift, the choice that issues the calling is His gift. You end up, with Luther himself, in the doctrine of unconditional election — which is exactly where Luther landed in his book against Erasmus, The Bondage of the Will.

Luther considered The Bondage of the Will the most important book he ever wrote. He told Erasmus, in essence: you have located the real argument. Free will versus sovereign grace is not a side issue — it is THE issue. And he chose his side without flinching: the will of fallen man is bound, captive, dead. Salvation is from first to last the work of God on a will that could not have done otherwise. (For the full Scriptural case, see our page on total depravity.)

What Luther's Story Proves

Luther's tower experience proves something that should be embarrassing to the modern doctrine of the autonomous will. Here was a man whose religious effort was off the charts, whose theological knowledge was world-class, whose desperation to please God was so intense it nearly destroyed his body — and none of it produced peace. Peace came when he stopped trying to produce righteousness and started receiving it.

This is the entire gospel collapsed into one biographical event. Justification is not God meeting your effort halfway. It is God doing what only He can do — declaring sinners righteous in Christ — and then giving them the faith to believe it. The Reformation did not merely correct an indulgence abuse. The Reformation was one terrified monk being shown that the door he had been hammering on for ten years was opening from the other side, and had been the whole time.

The God Luther had hated, he ended up loving. The phrase that had been a guillotine became a doorway. And the gates of paradise opened, in his own words, through faith — by which he always meant the kind of faith that is itself a gift, given to a will that did not know it needed it until grace made it know.
