The Example of Martin Luther.

The statements made in relation to the early life and religious experience of Martin Luther, may perhaps throw some light upon this subject. Earnestly desirous of living to God sincerely and wholly, it is said of him, that he “gave himself up to all the rigors of an ascetic life. He endeavored to crucify the flesh by fastings, macerations, and watchings. Shut up in his cell, as in a prison, he was continually struggling against the evil thoughts and inclinations of his heart. Never did a cloister witness efforts more sincere and unwearied to purchase eternal happiness.”—At a somewhat later period, he was in the city of Rome; and although he had received some greater light than at the period, to which we have just referred, he seems not as yet fully to have understood, how we can be forgiven and sanctified by faith in Christ alone. “One day,” says the writer of his life; “wishing to obtain an indulgence promised by the Pope to any one, who should ascend on his knees what is called Pilate’s Staircase, the poor Saxon monk was slowly climbing those steps, which they told him had been miraculously transported from Jerusalem to Rome. But, while he was going through this, [as he supposed] meritorious work, he thought he heard a voice like thunder speaking from the depth of his heart: THE JUST SHALL LIVE BY FAITH. 

These words, which already on two occasions had struck upon his ear as the voice of an angel of God, resounded instantaneously and powerfully within him. He started up in terror on the steps up which he had been crawling; he was horrified at himself; and struck with shame for the degradation, to which superstition had debased him, he fled from the scene of his folly.This remarkable passage of Scripture, THE JUST SHALL LIVE BY FAITH, “had a mysterious influence,” the historian of the Protestant Reformation further remarks, on the life of Luther: 

"It was by means of that word, that God then said, Let there be light, and there was light.—It is frequently necessary, that a truth should be repeatedly presented to our minds, in order to produce its due effect. Luther had often studied the Epistles to the Romans, and yet never had justification by faith, as there taught, appeared so clear to him. He now understood that righteousness, which alone can stand in the sight of God; he was now partaker of that perfect obedience of Christ, which God imputes freely to the sinner, as soon as he looks in humility to the God-man crucified. This was the decisive epoch in the inward life of Luther. That faith, which had saved him from the fear of death, became henceforward the soul of his theology; a strong hold in ever danger, giving power to his preaching and strength to his charity, constituting a ground of peace, a motive to service, and a consolation in life and death.”
