Every man who walks with God, and finds Him a present Help in every time of need; who puts His promises to the practical proof and verifies them in actual experience; every believer who with the key of faith unlocks God's mysteries, and with the key of prayer unlocks God's treasuries, thus furnishes to the race a demonstration and an illustration of the fact that "He is, and is a Rewarder of them that diligently seek Him." George Mueller was such an argument and example incarnated in human flesh. Here was a man of like passions as we are and tempted in all points like as we are, but who believed God and was established by believing; who prayed earnestly that he might live a life and do a work which should be a convincing proof that God hears prayer and that it is safe to trust Him at all times; and who has furnished just such a witness as he desired. Like Enoch, he truly walked with God, and had abundant testimony borne to him that he pleased God. And when, on the tenth day of March, 1898, it was told us of George Mueller that "he was not," we knew that "God had taken him" it seemed more like a translation than like death. To those who are familiar with his long life-story, and, most of all, to those who intimately knew him and felt the power of personal contact with him, he was one of God's ripest saints and himself a living proof that a life of faith is possible; that God may be known, communed with, found, and may become a conscious companion in the daily life. George Mueller proved for himself and for all others who will receive his witness that, to those who are willing to take God at His word and to yield self to His will, He is "the same yesterday and to-day and forever" that the days of divine intervention and deliverance are past only to those with whom the days of faith and obedience are past-in a word, that believing prayer works still the wonders which our fathers told of in the days of old.
