It now remained to be seen whether Semler's boldness would overleap itself, or prove the ruin of the religious spirit of the Continent for generations. The result, whatever it might be, was soon to be decided. For such views as he was propagating throughout the Protestant church of Germany could not fail to determine speedily the drift of the public sentiment of his day. His work, though destructive, was in conflict with the pure beauty of his private life. And here we look at him as one of the enigmas of human biography. True to his tenet that a man's public teachings need not influence his personal living, he was at once a teacher of skepticism and an example of piety. His Moravian origin and Pietistic training he could never forget; nor do we believe he attempted it. No doubt the asperity that he witnessed at Halle did much to repel him from the harsher side of Pietism. When he heard his room-mate praying aloud three hours a day upon his knees; and when he was advised to lay aside all extensive studies, because he would never be converted while pursuing them, he began to question whether intellectual progress were compatible with deep piety. The conclusion at which he arrived was against the intellectuality of the creed of Spener, but in favor of the spiritual purity of the life of his disciples. Through Semler's entire career we can find traces of that devoted spirit which had shined so brightly in his early youth, and which, in late life, he was not ashamed to confess. "There was no corner in the whole house," said he, "where I did not kneel, and pray, and weep alone that God might, out of his infinite mercy, pardon my sins. I felt that I was under the bondage of the law. Moravian songs seemed to be of very little help to me. I examined myself carefully to see whether or not I clung to any sin either consciously or ignorantly. I reproached myself several times for only giving one penny to the poor-collection when I had several pence in my pocket. My father would give me more the next time to make up my deficiency, and this was a great delight to me. It is now one of the pleasantest memories of my university-life that I used to give pieces of money to the poor."
