When, in 1870, the wife fell asleep in Jesus, and Mr. Muller was himself ill, he opened his heart to Mr. Wright as to the succession. Humility led him to shrink from such a post, and his then wife feared it would prove too burdensome for him; but all objections were overborne when it was seen and felt to be God's call. It was twenty-one months after this, when, in November, 1871, Mr. Wright was married to Mr. Muller's only daughter and child, so that it is quite apparent that he had neither sought the position he now occupies, nor was he appointed to it because he was Mr. Muller's son-in-law, for, at that time, his first wife was living and in health. From May, 1872, therefore, Mr. Wright _shared_ with his father-in-law the responsibilities of the Institution, and gave him great joy as a partner and successor in full sympathy with all the great principles on which his work had been based. A little over three years after Mr. Muller's second marriage, in March, 1874, Mrs. Muller was taken ill, and became, two days later, feverish and restless, and after about two weeks was attacked with hemorrhage which brought her also very near to the gates of death. She rallied; but fever and delirium followed and obstinate sleeplessness, till, for a second time, she seemed at the point of death. Indeed so low was her vitality that, as late as April 17th, a most experienced London physician said that he had never known any patient to recover from such an illness; and thus a third time all human hope of restoration seemed gone. And yet, in answer to prayer, Mrs. Muller was raised up, and in the end of May, was taken to the seaside for change of air, and grew rapidly stronger until she was entirely restored. Thus the Lord spared her to be the companion of her husband in those years of missionary touring which enabled him to bear such worldwide witness. Out of the shadow of his griefs this beloved man of God ever came to find that divine refreshment which is as the "shadow of a great rock in a weary land." CHAPTER XVII THE PERIOD OF WORLD-WIDE WITNESS GOD'S real answers to prayer are often seeming denials. Beneath the outward request He hears the voice of the inward desire, and He responds to the mind of the Spirit rather than to the imperfect and perhaps mistaken words in which the yearning seeks expression. Moreover, His infinite wisdom sees that a larger blessing may be ours only by the withholding of the lesser good which we seek; and so all true prayer trusts Him to give His own answer, not in our way or time, or even to our own expressed desire, but rather to His own unutterable groaning within us which He can interpret better than we. Monica, mother of Augustine, pleaded with God that her dissolute son might not go to Rome, that sink of iniquity; but he was permitted to go, and thus came into contact with Ambrose, bishop of Milan, through whom he was converted. God fulfilled the mother's _desire_ while denying her _request._
