October 15 – Martin Luther: The Spark of the Reformation

If there is one name that towers over the history of the Reformation, it is Martin Luther. A German monk turned reformer, Luther’s bold stand for the gospel reshaped the church and the world. By nailing his Ninety-Five Theses to the door of the Castle Church in Wittenberg on October 31, 1517, he lit a flame that still burns today.

From Monk to Reformer

Martin Luther was born in 1483 in Eisleben, Germany, to hardworking parents who hoped he would become a lawyer. But in 1505, after being caught in a thunderstorm and vowing to become a monk if God spared his life, Luther entered an Augustinian monastery.

As a monk, Luther was zealous—fasting, praying, confessing for hours. Yet the harder he tried to make himself righteous, the more guilty and hopeless he felt. His conscience was crushed under the weight of God’s holiness and his own sin.

The turning point came as Luther studied Scripture, especially Paul’s letter to the Romans. In Romans 1:17, he read: “The righteous will live by faith.” Suddenly, the gospel dawned. Righteousness was not something he achieved but something God granted through faith in Christ. This discovery changed everything.

The Ninety-Five Theses

Luther’s rediscovery of justification by faith collided with the church’s practice of selling indulgences. In 1517, Johann Tetzel was raising money for Rome by selling indulgences, claiming they could free souls from purgatory. Outraged, Luther wrote his Ninety-Five Theses, challenging this corruption. On October 31, he posted them to the church door in Wittenberg, inviting debate.

Though meant as an academic challenge, the theses spread like wildfire across Europe, fueled by the new printing press. Suddenly, Luther found himself at the center of a movement.

Theology that Shook the World

Luther’s core convictions would become the heartbeat of the Reformation:

• Sola Scriptura: Scripture alone is the supreme authority for faith and life.

• Sola Fide: We are justified by faith alone, apart from works.

• Sola Gratia: Salvation is entirely a gift of God’s grace.

• Solus Christus: Christ alone is the mediator between God and man.

• Soli Deo Gloria: All glory belongs to God alone.

These truths freed believers from the tyranny of a works-based system and pointed them to Christ’s finished work.

The Diet of Worms

In 1521, Luther was summoned to the Diet of Worms, an imperial council, to recant his writings. Standing before the emperor and church officials, he refused. “Unless I am convinced by Scripture and plain reason… my conscience is captive to the Word of God. I cannot and I will not recant. Here I stand, I can do no other. God help me.”

With those words, Luther defied the might of Rome and placed Scripture above all human authority. He was declared an outlaw, but under the protection of Frederick the Wise, he continued his work.

Translation of the Bible

While hiding in Wartburg Castle, Luther translated the New Testament into German, giving ordinary people direct access to God’s Word. This translation shaped both the German language and the hearts of countless believers. His hymns, such as A Mighty Fortress Is Our God, filled homes and churches with praise rooted in gospel truth.

Legacy

Luther died in 1546, having seen his reforms spread far beyond Germany. His rediscovery of the gospel reshaped the church, birthed Protestantism, and ignited a global movement.

Yet Luther’s legacy is not without flaws. His harsh writings against certain groups remain a stain. Still, his central message—that sinners are justified by faith in Christ alone—remains one of the greatest recoveries in church history.

Biblical Reflection

Romans 1:17 captures the essence of Luther’s theology:

“The righteous will live by faith.”

This verse shattered the chains of works-righteousness for Luther and became the rallying cry of the Reformation.

Application for Today

Martin Luther’s life challenges us to:

1. Rest in the Gospel – Like Luther, we must learn that righteousness is not achieved but received by faith in Christ.

2. Stand on Scripture – Luther risked everything because his conscience was captive to God’s Word. Are we willing to do the same?

3. Proclaim Christ Boldly – His hymns, sermons, and writings spread gospel truth far and wide. We too must proclaim Christ in our generation.

Conclusion

Martin Luther was not seeking to start a revolution, but by standing on God’s Word, he sparked the greatest renewal the church had seen since the days of the apostles. His discovery of justification by faith alone still sets captives free. His story calls us to stand firm, trust Christ, and live by faith in the God who justifies the ungodly.
