To return. The young man, now nearly twenty-two years of age, intent on the duties and trials of a missionary life, starts for his native New Hampshire, improving every opportunity on the way, where circumstances united with his own impressions in producing the conviction that good might be done. Without abating his own labor, he depends continually on divine assistance, believing that he enjoys the advantage of the real presence of the One who said, "Lo! I am with you alway;" and before undertaking any important cause, or plan of action, he seeks illumination in secret prayer, then follows the leading impressions of his mind. He diligently studies the Scriptures, observes nature, and discriminates the strong points and peculiarities of the different characters he meets, for which he seemed to possess an intuitive power that received no assistance from the later inductions of phrenology, or the didactic lessons of physiognomy. He could, without rules admitting of statement, readily discern the character of an audience, the kind of discourse fitted to their capacity and wants, and most easily did he arrive at this kind of knowledge by a brief social contact with individuals. No nature perhaps ever had a greater power of adaptability to the many-phased character of mankind and surrounding circumstances, than his. But for the present, indeed for the several years of his early ministry, the central element of his life, the one that ruled all others, was his earnest, hearty, prayerful devotion to the holy mission of saving human beings from sin, and of bringing them into living union with God and with Christ. Along the meanderings of this current let us therefore follow the course of his narrative, which at this time unfolds itself in a series of letters, hastily and unelaborately written to some friend whose name does not appear; perhaps to Z. Adams, or to some other young minister interested in his welfare.
