There are several important episodes in Mr. Muller's history which may be lightly passed by, because not so characteristic of him as that they might not have been common to many others, and therefore not constituting features so distinguishing this life from others as to make it a special lesson to believers.
For example, early in 1835 he made a visit to Germany upon a particular errand. He went to aid Mr. Groves, who had come from the East Indies to get missionary recruits, and who asked help of him, as of one knowing the language of the country, in setting the claims of India before German brethren, and pleading for its unsaved millions.
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!"
On June 22, 1835, Mr. Muller's father-in-law, Mr. Groves, died; and both of his own children were very ill, and four days later little Elijah was taken. Both parents had been singularly prepared for these bereavements, and were divinely upheld. They had felt no liberty in prayer for the child's recovery, dear as he was; and grandfather and grandson were laid in one grave. Henceforth Mr. and Mrs. Muller were to have no son, and Lydia was to remain their one and only child.
