He saw this to be one of those "names" of Jehovah which He reveals to His people to lead them to trust in Him, as it is written in Psalm ix. 10:
"They that know Thy name Will put their trust in Thee."
These five words from the sixty-eighth psalm became another of his life-texts, one of the foundation stones of all his work for the fatherless. These are his own words:
"By the help of God, this shall be my argument before Him, respecting the orphans, in the hour of need. He is their Father, and therefore has pledged Himself, as it were, to provide for them; and I have only to remind Him of the need of these poor children in order to have it supplied."
This is translating the promises of God's word, not only into praying, but into living, doing, serving. Blessed was the hour when Mr. Müller learned that one of God's chosen names is "the Father of the fatherless"!
To sustain such burdens would have been quite impossible but for faith in such a God. In reply to oft-repeated remarks of visitors and observers who could not understand the secret of his peace, or how any man who had so many children to clothe and feed could carry such prostrating loads of care, he had one uniform reply: "By the grace of God, this is no cause of anxiety to me. These children I have years ago cast upon the Lord. The whole work is His, and it becomes me to be without carefulness. In whatever points I am lacking, in this point I am able by the grace of God to roll the burden upon my heavenly Father."*
* Journal 1:285
In tens of thousands of cases this peculiar title of God, chosen by Himself and by Himself declared, became to Mr. Müller a peculiar revelation of God, suited to his special need. The natural inferences drawn from such a title became powerful arguments in prayer, and rebukes to all unbelief. Thus, at the outset of his work for the orphans, the word of God put beneath his feet a rock basis of confidence that he could trust the almighty Father to support the work. And, as the solicitudes of the work came more and more heavily upon him, he cast the loads he could not carry upon Him who, before George Müller was born, was the Father of the fatherless.
About this time we meet other signs of the conflict going on in Mr. Müllers own soul. He could not shut his eyes to the lack of earnestness in prayer and fervency of spirit which at times seemed to rob him of both peace and power. And we notice his experience, in common with so many saints, of the paradox of spiritual life. He saw that "such fervency of spirit is altogether the gift of God," and yet he adds, "I have to ascribe to myself the loss of it." He did not run divine sovereignty into blank fatalism as so many do. He saw that God must be sovereign in His gifts, and yet man must be free in his reception and rejection of them. He admitted the mystery without attempting to reconcile the apparent contradiction. He confesses also that the same book, Philip's Life of Whitefield, which had been used of God to kindle such new fires on the altar of his heart, had been also used of Satan to tempt him to neglect for its sake the systematic study of the greatest of books.
Thus, at every step, George Müllers life is full of both encouragement and admonition to fellow disciples. While away from Bristol he wrote in February, 1838, a tender letter to the saints there, which is another revelation of the man's heart. He makes grateful mention of the mercies of God, to him, particularly His gentleness, long-suffering, and faithfulness and the lessons taught him through affliction. The letter makes plain that much sweetness is mixed in the cup of suffering, and that our privileges are not properly prized until for a time we are deprived of them. He particularly mentions how secret prayer, even when reading, conversation, or prayer with others was a burden, always brought relief to his head. Converse with the Father was an indispensable source of refreshment and blessing at all times. As J. Hudson Taylor says "Satan, the Hinderer, may build a barrier about us, but he can never roof us in, so that we cannot look up." Mr. Müller also gives a valuable hint that has already been of value to many afflicted saints, that he found he could help by prayer to fight the battles of the Lord even when he could not by preaching. After a short visit to Germany, partly in quest of health and partly for missionary objects, and after more than twenty-two weeks of retirement from ordinary public duties, his head was much better, but his mental health allowed only about three hours of daily work. While in Germany he had again seen his father and elder brother, and spoken with them about their salvation. To his father his words brought apparent blessing, for he seemed at least to feel his lack of the one thing needful. The separation from him was the more painful as there was so little hope that they should meet again on earth.
