The pathway of this man of God sometimes led through deep waters of affliction, but goodness and mercy still followed, and held him up. In the autumn of 1852, his beloved brother-in-law, Mr. A. N. Groves, came back from the East Indies, very ill; and in May of the next year, after blessed witness for God, he fell asleep at Mr. Muller's house. To him Mr. Muller owed much through grace at the outset of his labours in 1829. By his example his faith had been stimulated and helped when, with no visible support or connection with any missionary society, Mr. Groves had gone to Baghdad with wife and children, for the sake of mission work in this far-off field, resigning a lucrative practice of about fifteen hundred pounds a year. The tie between these men was very close and tender and the loss of this brother-in-law gave keen sorrow. In July following, Mr. and Mrs. Muller went through a yet severer trial. Lydia, the beloved daughter and only child,--born in 1832 and new-born in 1846, and at this time twenty years old and a treasure without price,--was taken ill in the latter part of June, and the ailment developed into a malignant typhoid which, two weeks later, brought her to the gates of death. These parents had to face the prospect of being left childless. But faith triumphed and prayer prevailed. Their darling Lydia was spared to be, for many years to come, a blessing beyond words, not only to them and to her future husband, but to many others in a wider circle of influence. Mr. Muller found, in this trial, a special proof of God's goodness and mercy, which he gratefully records, in the growth in grace, evidenced in his entire and joyful acquiescence in the Father's will, when, with such a loss apparently before him, his confidence was undisturbed that all things would work together for good. He could not but contrast with this experience of serenity, that broken peace and complaining spirit with which he had met a like trial in August, 1831, twenty-one years before. How, like a magnet among steel filings, the thankful heart finds the mercies and picks them out of the black dust of sorrow and suffering! The second volume of Mr. Muller's Narrative closes with a paragraph in which he formally disclaims as impudent presumption and pretension all high rank as a miracle-worker, and records his regret that any work, based on scriptural promises and built on the simple lines of faith and prayer, should be accounted either phenomenal or fanatical.
