I don't know much about Dr. Emile Cailliet, a professor at Princeton Seminary who died in 1981, but he has a fascinating conversion story. Her eis the story as told by Ray Stedman in 1982.
In his youth he was a total unbeliever. In fact, he vehemently opposed any kind of faith. He fought in the French Army in World War I, and the terrible pain of human life and death around him confirmed his conviction that there was nothing in religion that could satisfy men. But he longed to have something that would help him in times of difficulty, so he compiled a notebook which he called, "The Book That Would Understand Me." Whenever he ran across a quotation that struck fire in his mind he would copy it down in his book. Still a young man when the war was ended, he sat down one day to read the collection that he had put together. As he read it, his heart sank. He saw that since it came from himself, it had no power to minister to him in times of pressure and stress; it seemed flat and empty.
About that time a remarkable thing occurred. Purely by accident, one day his wife wandered into a courtyard she had never seen before. She realised she was in a Huguenot church, and she saw an old man sitting at a table. For some reason, unknown to her, she walked up to him and asked, "Do you have any Bibles in French?" Without a word, the man picked up a Bible from the table and handed it to her. She was afraid to give it to her husband because he had ordered that religion not even be mentioned in their house, but she finally told him of this unusual experience. He said, "Give me the Bible. Let me read it."
For the first time in his life he began to read the Bible. He started in the Gospels, which fascinated him. For many hours he read through several of the books of the Bible. Finally he put it down, and, bowing his head, he said, "At last I have found the Book that understands me." He opened his heart to the Lord and became a Christian. Ultimately he became a professor in a seminary. He bore testimony to his dying day that he never varied from that view of the Bible: "This is the Book that understands me."
