Of that faith something ought to be said. In his earliest letters which have been preserved, we can see how strongly he was influenced by forms of theology that have long since ceased to be regarded as Scriptural. That the heathen who had never heard of Christ were perishing eternally was a doctrine that inspired much missionary devotion. These dogmas, it is clear, very gradually became impossible to him in view of the actual facts of the vast heathen world. But the supreme motive never changed. In a letter written just at the time of his ordination, he expresses his sense of the honour done to him in being accepted by Christ Jesus as one of His witnesses. The absolute surrender of his own will and mind to “his fair Captain Christ” was the fact most fundamental to Livingstone’s whole career. To the last, he never felt that he was really in the way of duty unless he was doing missionary work and bearing witness to the lordship of Christ. Stanley bore his testimony to the practical character of Livingstone’s religion. “In him religion exhibits its loveliest features; it governs his conduct not only towards his servants, but towards the natives, the bigoted Mohammedans, and all who come in contact with him.” In another striking phrase, he says: “Religion has tamed him and made him a Christian gentleman.” Until his physical powers utterly failed, he never omitted to gather his men around him for evening service, read and pray with them, and add some simple exhortation. He was a man of deep convictions. Once thoroughly alive to some fact, he took a tenacious grip of it, and gave it a place in all his thinking. That was how it came to pass that neither the politicians nor the men of science could prevail upon him to leave the social sore of Africa to others and devote himself to exploration and discovery. Livingstone’s Puritan soul, that knew how to put first things in the first place, realised that the fact of most moment in Africa was not the sources of the Nile, but the sources of the slave trade. This great social problem had to be attacked if religious and spiritual work was not to be negatived. Much might be written about his courage in alienating those who sympathised with his work as an explorer and those who might have assisted him financially. He knew quite well that a price must be paid by any one who was really in earnest to destroy the slave trade. But nothing moved him. Henceforth it was a case of “this one thing I do.” Perhaps the most remarkable fact of all is, how early in his life he perceived that here lay the path he was to tread. There lies before me as I write an old brown and much torn letter which must have been the first he wrote from the Cape on his arrival there, and is dated March 10, 1841. Every inch of the large sheet is covered with writing, and among the last words is a reference to the resistance of certain of the Boers to the policy of emancipation. Then follows this sentence: “Oh!
