If there existed only one man or woman who did not love the Saviour, and if that person lived among the wilds of Siberia, and if it were necessary that all the millions of believers on the face of the earth should journey there, and every one of them plead with him to come to Jesus before he could be converted, it would be well worth all the zeal, labour, and expense. If we had to preach to thousands year after year, and never rescued but one soul, that one soul would be full reward for all our labour, for a soul is of countless price.
