But Luther's inward life demands a higher sympathy. It was a fearful period for him; he experienced together with a sense of elevation and victory, mortal anguish, tormenting doubts, and terrible temptations. He, with a few others, stood against the whole of Christendom, always opposed by the most powerful and implacable enemies; and these comprised all that he had from his youth considered most holy. What if he should be in error? He was answerable for every soul that he carried away with him. And whither was he taking them? What was there beyond the pale of the Church?--Destruction, temporal and eternal ruin. Opponents and timid friends cut his heart with reproaches and warnings, but incomparably greater was one pain, that secret gnawing and uncertainty which he dared not confess to any one. In prayer, indeed, he found peace; when his glowing soul soared up to God, he received abundance of strength, rest, and cheerfulness; but in his hours of relaxation, when his irritable spirit writhed under any obnoxious impressions, he felt himself embarrassed, torn asunder, and under the interdict of another power which was inimical to his God. From his childhood he had known how busily evil spirits hover around men, and from the Scriptures he had learned that the devil labours to injure even the purest. On his own path lurked busy devils seeking to weaken and entice him, and to make countless numbers miserable through him. He saw them working in the angry mien of the Cardinal, the sneering countenance of Eckius, and indeed in his own soul; and he knew how powerful they were in Rome. In his youth he had been tormented by apparitions, and now they had returned to him. Out of the dark shadows of his study rose the tempter as a spectre, clutching at his reason, and when praying, the devil approached him, even under the form of the Saviour, radiant as king of heaven, with his five wounds as the old Church represented him. But Luther knew that Christ only approaches weak man in his word, or in humble form, as He hung upon the cross; so by a violent effort he collected himself and cried out to the apparition: "Away with thee, thou vile devil!" then the spectre vanished.[30] Thus again and again for years did the stout heart of the man struggle with wild excitement. It was a gloomy conflict between reason and delusion; he always came out as conqueror, the primitive strength of his healthy character gained the victory. In long hours of prayer the stormy waves of excitement were calmed; his solid understanding and his conscience led him always from doubt to security, and he felt this expansion of his soul as a gracious inspiration from his God. It was after such experiences, that he, who had been so anxious and timid, became firm as steel, indifferent to the judgment of men, intrepid and inexorable.
