He had learned many things since those days when he had scampered barefoot over the fields, or down the road to school. He had been to college in Toronto, in Princeton, and away over in Edinburgh, in the old homeland where his father and mother were born. And all through his life that call to go and do great deeds for the King had come again and again. He had determined to obey it when he was but a little lad at school. He had encountered many big stones in his way, which he had to break, before he could go on. But the biggest stone of all lay across his path when college was over, and he was ready and anxious to go away as a missionary. The Presbyterian Church of Canada had never yet sent out a missionary to a foreign land, and some of the good old men bade George Mackay stay at home and preach the gospel there. But as usual he conquered. Every one saw he would be a great missionary if he were only given a chance. At last the General Assembly gave its consent, and now, in spite of all stones in the way, here he was, bound for China, and ready to do anything the King commanded. Land was beginning to fade away into a gray mist, the November wind was damp and chill, he turned and went down to his stateroom. He sat down on his little steamer trunk, and for the first time the utter loneliness and the uncertainty of this voyage came over him. He took up his Bible and turned to the fly-leaf. There he read the inscription: Presented to REV. G. L. MACKAY First missionary of the Canadian Presbyterian Church to China, by the Foreign Mission Committee, as a parting token of their esteem, when about to leave his native land for the sphere of his future labors among the heathen. WILLIAM MACLAREN, Convener. Ottawa, 9th October, 1871. Matthew xxviii: 18-20. Psalm cxxi It was a moment of severe trial to the young soldier. But he turned to the Psalm marked on the fly-leaf of his Bible, and he read it again and again. "My help cometh from the Lord which made heaven and earth" "The Lord is thy keeper: the Lord is thy shade upon thy right hand." "The sun shall not smite thee by day, nor the moon by night." The beautiful words gave him comfort. Homesickness, loneliness, and fears for the future all vanished. He was going out to an unknown land where dangers and perhaps death awaited him, but the Lord would be his keeper and nothing could harm him.
