At the same time he felt that the curacy of souls must not be neglected by reason of his absorption in either work or prayer. Both believers and inquirers needed pastoral oversight; neither himself nor his brother Craik had time enough for visiting so large a flock, many of whom were scattered over the city; and about fifty new members were added every year who had special need of teaching and care. Again, as there were two separate congregations, the number of meetings was almost doubled; and the interruptions of visitors from near and far, the burdens of correspondence, and the oversight of the Lord's work generally, consumed so much time that even with two pastors the needs of the church could not be met. At a meeting of both congregations in October, these matters were frankly brought before the believers, and it was made plain that other helpers should be provided, and the two churches so united as to lessen the number of separate meetings. In October, 1837, a building was secured for a third orphan house, for boys; but as the neighbours strongly opposed its use as a charitable institution, Mr Muller, with meekness of spirit, at once relinquished all claim upon the premises, being mindful of the maxim of Scripture: "As much as lieth in you, live peaceably with all men." (Rom. xiii. 18.) He felt sure that the Lord would provide, and his faith was rewarded in the speedy supply of a building in the same street where the other two houses were. Infirmity of the flesh again tried the faith and patience of Mr. Muller. For eight weeks he was kept out of the pulpit. The strange weakness in the head, from which he had suffered before and which at times seemed to threaten his reason, forced him to rest; and in November he went to Bath and Weston-super-Mare, leaving to higher Hands the work to which he was unequal. One thing he noticed and recorded: that, even during this head trouble, prayer and Bible-reading could be borne better than anything else. He concluded that whenever undue carefulness is expended on the body, it is very hard to avoid undue carelessness as to the soul; and that it is therefore much safer comparatively to disregard the body, that one may give himself wholly to the culture of his spiritual health and the care of the Lord's work. Though some may think that in this he ran to a fanatical extreme, there is no doubt that such became more and more a law of his life. He sought to dismiss all anxiety, as a duty; and, among other anxious cares, that most subtle and seductive form of solicitude which watches every change of symptoms and rushes after some new medical man or medical remedy for all ailments real or fancied.
