Luther

While one day examining the books in the library of the university, Luther discovered a Latin Bible.... With mingled awe and wonder he turned the sacred pages; with quickened pulse and throbbing heart he read for himself the words of life, pausing now and then to exclaim, “Oh, if God would give me such a book for my own!” Angels of heaven were by his side, and rays of light from the throne of God revealed the treasures of truth to his understanding.—The Spirit of Prophecy 4:96.TA 244.2

When enemies appealed to custom and tradition, or to the assertions and authority of the pope, Luther met them with the Bible and the Bible alone. Here were arguments which they could not answer; therefore the slaves of formalism and superstition clamored for his blood.... But Luther did not fall a prey to their fury. God had a work for him to do, and angels of heaven were sent to protect him.—The Spirit of Prophecy 4:108, 109.TA 245.1

Here was one lone man who had stirred the rage of priests and people. He was summoned to Augsburg to answer for his faith. He obeyed the summons. Firm and undaunted he stood before those who had caused the world to tremble—a meek lamb surrounded by angry lions—yet for the truth's sake, and for Christ's sake, he stood up undaunted, and with holy eloquence, which the truth can alone inspire, he gave the reasons of his faith. They tried various means to silence the bold advocate for truth. They flattered and held out inducements; he should be exalted and honored; but life and honors were valueless to him, if purchased at the sacrifice of the truth.TA 245.2

Brighter and clearer shone the Word of God upon his understanding, giving him a more vivid sense of the errors, corruptions, and hypocrisy of the papacy. His enemies sought to intimidate him, and cause him to renounce his faith, but he boldly stood in defense of the truth. He was ready to die for his faith, if God required; but to yield it—never. God preserved his life. He bade angels attend him, and bring him through the stormy conflict, unharmed, and he baffled the rage and purposes of his enemies.—Spiritual Gifts 4b:118, 119.TA 245.3

Had the eyes of the assembly [at Worms] been opened, they would have beheld angels of God in the midst of them, shedding beams of light athwart the darkness of error, and opening minds and hearts to the reception of truth.—The Spirit of Prophecy 4:124.TA 246.1
