The common ways of accounting for its success would be absurdly ridiculous and amusing were they not so sadly unbelieving. Those who knew little or nothing, either of the exercise of faith or the experience of God's faithfulness, resorted to the most God-dishonouring explanations of the work. Some said: "Mr. Muller is a foreigner; his methods are so novel as to attract attention." Others thought that the "Annual Reports brought in the money," or suggested that he had "a _secret treasure."_ His quiet reply was, that his being a foreigner would be more likely to repel than to attract confidence; that the novelty would scarcely avail him after more than a score of years; that other institutions which issued reports did not always escape want and debt; but, as to the secret treasure to which he was supposed to have access, he felt constrained to confess that there was _more in that supposition than the objectors were aware of._ He had indeed a Treasury, inexhaustible--in the promises of a God unchangeably faithful--from which he admits that he had already in 1856 drawn for twenty-two years, and in all over one hundred and thirteen thousand pounds. As to the Reports, it may be worth while to notice that he never but once in his life advertised the public of any need, and that was the _need of more orphans_--more to care for in the name of the Lord--a single and singular ease of advertising, by which he sought not to increase his _income,_ but his _expenditure_--not asking the public to aid him in supporting the needy, but to increase the occasion of his outlay! So far was he from depending upon any such sources of supply as the unbelieving world might think, that it was in the drying up of all such channels that he found the opportunity of his faith and of God's power. The visible treasure was often so small that it was reduced to nothing, but the invisible Treasure was God's riches in glory, and could be drawn from without limit. This it was to which he looked alone, and in which he felt that he had a river of supply that can never run dry.* * Appendix H. The orphan work had, to Mr. Muller, many charms which grew on him as he entered more fully into it. While his main hope was to be the means of spiritual health to these children, he had the joy of seeing how God used these homes for the promotion of their physical welfare also, and, in cases not a few, for the entire renovation of their weak and diseased bodies. It must be remembered that most of them owed their orphan condition to that great destroyer, Consumption. Children were often brought to the orphan houses thoroughly permeated by the poison of bad blood, with diseased tendencies, and sometimes emaciated and half-starved, having had neither proper food nor medical care.
