Again, in his journal he constantly seeks to save from reproach the good name of Him whom he serves: he cannot have such a God accounted a hard Master. So early as July, 1831, a false rumour found circulation that he and his wife were half-starving and that certain bodily ailments were the result of a lack of the necessities of life; and he is constrained to put on record that, though often brought so low as not to have one penny left and to have the last bread on the table, they had never yet sat down to a meal unprovided with some nourishing food. This witness was repeated from time to time, and until just before his departure for the Father's house on high; and it may therefore be accepted as covering that whole life of faith which reached over nearly threescore years and ten. A kindred word of testimony, first given at this same time and in like manner reiterated from point to point in his pilgrimage, concerns the Lord's faithfulness in accompanying His word with power, in accordance with that positive and unequivocal promise in Isaiah lv. 11: "My word shall not return unto Me void; but it shall accomplish that which I please, and it shall prosper in the thing whereto I sent it." It is very noticeable that this is not said of _man's_ word, however wise, important, or sincere, but of _God's_ word. We are therefore justified in both expecting and claiming that, just so far as our message is not of human invention or authority, but is God's message through us, it shall never fail to accomplish His pleasure and its divine errand, whatever be its apparent failure at the time. Mr. Muller, referring to his own preaching, bears witness that in almost if not quite every place where he spoke God's word, whether in larger chapels or smaller rooms, the Lord gave the seal of His own testimony. He observed, however, that blessing did not so obviously or abundantly follow his open-air services: only in one instance had it come to his knowledge that there were marked results, and that was in the case of an army officer who came to make sport. Mr. Muller thought that it might please the Lord not to let him see the real fruit of his work in open-air meetings, or that there had not been concerning them enough believing prayer; but he concluded that such manner of preaching was not his present work, since God had not so conspicuously sealed it with blessing. His journal makes very frequent reference to the physical weakness and disability from which he suffered. The struggle against bodily infirmity was almost life-long, and adds a new lesson to his life-story. The strength of faith had to triumph over the weakness of the flesh. We often find him suffering from bodily ills, and sometimes so seriously as to be incapacitated for labour.
