If George Muller could still speak to us, he would again repeat the warning so frequently found in his journal and reports, that his fellow disciples must not regard him as a _miracle-worker,_ as though his experience were to be accounted so exceptional as to have little application in our ordinary spheres of life and service. With patient repetition he affirms that in all essentials such an experience is the privilege of all believers. God calls disciples to various forms of _work,_ but all alike to the same _faith._ To say, therefore, "I am not called to build orphan houses, etc., and have no right to expect answers to my prayers as Mr. Muller did," is wrong and unbelieving. Every child of God, he maintained, is first to get into the sphere appointed of God, and therein to exercise full trust, and live by faith upon God's sure word of promise. Throughout all these thousands of pages written by his pen, he teaches that every experience of God's faithfulness is both the reward of past faith and prayer, and the preparation of the servant of God for larger work and more efficient service and more convincing witness to his Lord. No man can understand such a work who does not see in it the _supernatural_ power of God. Without that the enigma defies solution; with that all the mystery is at least an open mystery. He himself felt from first to last that this supernatural factor was the key to the whole work, and without that it would have been even to himself a problem inexplicable. How pathetically we find him often comparing himself and his work for God to "the Burning Bush in the Wilderness" which, always aflame and always threatened with apparent destruction, was not consumed, so that not a few turned aside wondering to see this great sight. And why was it not burnt? Because Jehovah of hosts, who was in the Bush, dwelt in the man and in his work: or, as Wesley said with almost his last breath, "Best of all, God is with us." This simile of the Burning Bush is the more apt when we consider the _rapid growth of the work._ At first so very small as to seem almost insignificant, and conducted in one small rented house, accommodating thirty orphans, then enlarged until other rented premises became necessary; then one, two, three, four, and even five immense structures being built, until three hundred, seven hundred, eleven hundred and fifty, and finally two thousand and fifty inmates could find shelter within them,--how seldom has the world seen such vast and, at the same time, rapid enlargement! Then look at the outlay! At first a trifling expenditure of perhaps five hundred pounds for the first year of the Scriptural Knowledge Institution, and of five hundred pounds for the first twelve month of the orphan work, and in the last year of Mr. Muller's life a grand total of over twenty-seven thousand five hundred, for all the purposes of the Institution.
