When Mr. Muller went to the alien office in London to get a passport, he found that, through ignorance, he had broken the law which required every alien semi-annually to renew his certificate of residence, under penalty of fifty pounds fine or imprisonment. He confessed to the officer his non-compliance, excusing himself only on the ground of ignorance, and trusted all consequences with God, who graciously inclined the officer to pass over his non-compliance with the law. Another hindrance which still interfered with obtaining his passport, was also removed in answer to prayer; so that at the outset he was much impressed with the Lord's sanction of his undertaking. His sojourn abroad continued for nearly two months, during which time he was at Paris, Strasburg, Basle, Tubingen, Wurtemberg, Sehaffhausen, Stuttgart, Halle, Sandersleben, Aschersleben, Heimersleben, Halberstadt, and Hamburg. At Halle, calling on Dr. Tholuck after seven years of separation, he was warmly welcomed and constrained to lodge at his house. From Dr. Tholuck he heard many delightful incidents as to former fellow students who had been turned to the Lord from impious paths, or had been strengthened in their Christian faith and devotion. He also visited Francke's orphan houses, spending an evening in the very room where God's work of grace had begun in his heart, and meeting again several of the same little company of believers that in those days had prayed together. He likewise gave everywhere faithful witness to the Lord. While at his father's house the way was opened for him to bear testimony indirectly to his father and brother. He had found that a direct approach to his father upon the subject of his soul's salvation only aroused his anger, and he therefore judged that it was wiser to refrain from a course which would only repel one whom he desired to win. An unconverted friend of his father was visiting him at this time, before whom he put the truth very frankly and fully, in the presence of both his father and brother, and thus quite as effectively gave witness to them also. But he was especially moved to pray that he might by his whole life bear witness at his home, manifesting his love for his kindred and his own joy in God, his satisfaction in Christ, and his utter indifference to all former fascinations of a worldly and sinful life, through the supreme attraction he found in Him; for this, he felt sure, would have far more influence than any mere words: our walk counts for more than our talk, always. The effect was most happy. God so helped the son to live before the father that, just before his leaving for England, he said to him: "My son, may God help me to follow your example, and to act according to what you have said to me!"
