With patience and wisdom he unravelled the tangled skein of my perplexity and difficulty, and helped me to settle upon biblical principles all matters of so-called expediency. As he left me, about to visit other cities, his words fixed themselves in my memory. I had expressed to him my growing conviction that the worship in the churches had lost its primitive simplicity; that the pew-rent system was pernicious; that fixed salaries for ministers of the gospel were unscriptural; that the church of God should be administered only by men full of the Holy Ghost, and that the duty of Christians to the non-church-going masses was grossly neglected, etc. He solemnly said to me: "My beloved brother, the Lord has given you much light upon these matters, and will hold you correspondingly responsible for its use. If you obey Him and walk in the light, you will have more; if not, the light will be withdrawn." It is a singular lesson on the importance of an anointed tongue, that forty simple words, spoken over twenty years ago, have had a daily influence on the life of him to whom they were spoken. Amid subtle temptations to compromise the claims of duty and hush the voice of conscience, or of the Spirit of God, and to follow the traditions of men rather than the word of God, those words of that venerated servant of God have recurred to mind with ever fresh force. We risk the forfeiture of privileges which are not employed for God, and of obscuring convictions which are not carried into action. God's word to us is _"use or lose."_ "To him that hath shall be given: from him that hath not shall be taken away even that which he seemeth to have." It is the hope and the prayer of him who writes this memoir that the reading of these pages may prove to be an interview with the man whose memorial they are, and that the witness borne by George Muller may be to many readers a source of untold and lifelong blessing. It need not be said that to carry out conviction into action is a costly sacrifice. It may make necessary renunciations and separations which leave one to feel a strange sense both of deprivation and loneliness. But he who will fly as an eagle does into the higher levels where cloudless day abides, and live in the sunshine of God, must consent to live a comparatively lonely life. No bird is so solitary as the eagle. Eagles never fly in flocks: one, or at most two, and the two, mates, being ever seen at once. But the life that is lived unto God, however it forfeits human companionship, knows divine fellowship, and the child of God who like his Master undertakes to "do always the things that please Him," can like his Master say, "The Father hath not left me alone." "I am alone; yet not alone, for the Father is with me." Whosoever will promptly follow whatever light God gives, without regard to human opinion, custom, tradition, or approbation, will learn the deep meaning of these words: "Then shall we know, if we follow on to know the Lord."
