Scarcely were the orphans thus housed on Ashley Down, before Mr. Muller's heart felt enlarged desire that one thousand, instead of three hundred, might enjoy such privileges of temporal provision and spiritual instruction; and, before the new year, 1851, had dawned, this yearning had matured into a purpose. With his uniform carefulness and prayerfulness, he sought to be assured that he was not following self-will, but the will of God; and again in the scales of a pious judgment the reasons for and against were conscientiously weighed. Would he be going 'beyond his measure,' spiritually, or naturally? Was not the work, with its vast correspondence and responsibility, already sufficiently great? Would not a new orphan house for three hundred orphans cost another fifteen thousand pounds, or, if built for seven hundred, with the necessary ground, thirty-five thousand? And, even when built and fitted and filled, would there not be the providing for daily wants, which is a perpetual care, and cannot be paid for at once like a site and a building? It would demand eight thousand pounds annual outlay to provide for another seven hundred little ones. To all objections the one all-sufficient answer was the all-sufficient God; and, because Mr. Muller's eye was on His power, wisdom, and riches, his own weakness, folly, and poverty were forgotten. Another objection was suggested: What if he should succeed in thus housing and feeding a thousand poor waifs, what would become of the institution _after his death?_ The reply is memorable: "My business is, with all my might, to _serve my own generation by the will of God:_ in so doing I shall best serve the next generation, should the Lord Jesus tarry." Were such objection valid, it were as valid against beginning any work likely to outlive the worker. And Mr. Muller remembered how Francke at Halle had to meet the same objection when, now over two hundred years ago, he founded the largest charitable establishment which, up to 1851, existed in the world. But when, after about thirty years of personal superintendence, Francke was taken away, his son-in-law, as we have seen, became the director. That fellow countryman who had spoken to Mr. Muller's soul in 1826, thus twenty-five years later encouraged him to go forward, to do his own duty and leave the future to the Eternal God.
Several reasons are recorded by Mr. Muller as specially influencing still further advance: the many applications that could not, for want of room, be accepted; the low moral state of the poorhouses to which these children of poverty were liable to be sent; the large number of distressing cases of orphanhood, known to be deserving of help; the previous experiences of the Lord's gracious leading and of the work itself; his calmness in view of the proposed expansion; and the spiritual blessing possible to a larger number of homeless children. But one reason overtopped all others: an enlarged service to man, attempted and achieved solely in dependence upon God, would afford a correspondingly weightier witness to the Hearer of prayer. These reasons, here recorded, will need no repetition in connection with subsequent expansions of the work, for, at every new stage of advance, they were what influenced this servant of God.
On January 4, 1851, another offering was received, of three thousand pounds--the largest single donation up to that date--which, being left entirely to his own disposal, encouraged him to go forward.
Again, he kept his own counsel. Up to January 25th, he had not mentioned, even to his own wife, his thought of a further forward movement, feeling that, to avoid all mistakes, he must first of all get clear light from God, and not darken it by misleading human counsel. Not until the Twelfth Report of the Scriptural Knowledge Institution was issued, was the public apprised of his purpose, with God's help to provide for seven hundred more needy orphans.
