Going back to Halle, he said to himself, 'This is the _true way to preach,_' albeit he felt misgivings lest such a simple style of exposition might not suit so well a cultured refined city congregation. He had yet to learn how the enticing words of man's wisdom make the cross of Christ of none effect, and how the very simplicity that makes preaching intelligible to the illiterate makes sure that the most cultivated will also understand it, whereas the reverse is not true. Here was another very important _step in his preparation_ for subsequent service. He was to rank throughout life among the simplest and most scriptural of preachers. This first trial of pulpit-work led to frequent sermons, and in proportion as his speech was in the simplicity that is in Christ did he find joy in his work and a harvest from it. The committed sermon of some great preacher might draw forth human praise, but it was the simple witness of the Word, and of the believer to the Word, that had praise of God. His preaching was not then much owned of God in fruit. Doubtless the Lord saw that he was not ready for reaping, and scarcely for sowing: there was yet too little prayer in preparation and too little unction in delivery, and so his labours were comparatively barren of results. About this same time he took another step--perhaps the most significant thus far in its bearing on the precise form of work so closely linked with his name. For some two months he availed himself of the free lodgings furnished for poor divinity students in the famous _Orphan Houses built by A. H. Francke._ This saintly man, a professor of divinity at Halle, who had died a hundred years before (1727), had been led to found an orphanage in entire dependence upon God. Half unconsciously George Muller's whole life-work at Bristol found both its suggestion and pattern in Francke's orphanage at Halle. The very building where this young student lodged was to him an object lesson--a visible, veritable, tangible proof that the Living God hears prayer, and can, in answer to prayer alone, build a house for orphan children. That lesson was never lost, and George Muller fell into the apostolic succession of such holy labour! He often records how much his own faith-work was indebted to that example of simple trust in prayer exhibited by Francke. Seven years later he read his life, and was thereby still more prompted to follow him as he followed Christ. George Muller's spiritual life in these early days was strangely chequered. For instance, he who, as a Lutheran divinity student, was essaying to preach, hung up in his room a framed crucifix, hoping thereby to keep in mind the sufferings of Christ and so less frequently fall into sin. Such helps, however, availed him little, for while he rested upon such artificial props, it seemed as though he sinned the oftener.
