This pamphlet comprises a series of articles originally written for The Indian Witness, at the editor's request. For much of the general background of ideas I am indebted to Professor Henry Wright, of Yale Divinity School, and Mr. Frank N. D. Buchman, of Hartford Theological Seminary, who acknowledge their own vast debt to the pioneer in this field, Henry Drummond. Those who are aware of the very wide and rich experience of Dr. Wright and Mr. Buchman as successful personal evangelists, are waiting with eagerness for the volume on this theme upon which they are collaborating. Pending its appearance, this little study of certain phases of a subject on which, despite its importance, there is so little recent literature, may prove helpful to some. H.A.W.
