Farewell, my dear Thankful, thou wife of my youth, and mother of my first born; the beginning of my strength--farewell. Yet a few more lingering years of sorrow, pain and toil, and I shall be with thee, and clasp thee to my bosom, and thou shalt sit down on my throne, as a queen and priestess unto thy lord, arrayed in white robes of dazzling splendor and decked with precious stones and gold, while thy queen sisters shall minister before thee and bless thee, and thy sons and daughters innumerable shall call thee blessed, and hold thy name in everlasting remembrance. In the spring of 1837, soon after the death of my wife, I returned to Canada, to visit the Saints, and to confer on the subject of a mission to England. Several of the Saints in Canada were English, who had friends in England. Letters had already been sent to them with information of the rise of the Church, and of its principles. Several of the Canadian Elders felt a desire to go on a mission to their friends in that country. At length, Joseph Fielding, Isaac Russell, John Goodson and John Snider, of the Canada Elders, were selected for a mission to England. Elders H. C. Kimball and Orson Hyde, of the quorum of the Twelve, were selected to go at the head of the mission, and Elder Willard Richards was appointed to accompany them. About this time, after I had returned from Canada, there were jarrings and discords in the Church at Kirtland, and many fell away and became enemies and apostates. There were also envyings, lyings, strifes and divisions, which caused much trouble and sorrow. By such spirits I was also accused, misrepresented and abused. And at one time, I also was overcome by the same spirit in a great measure, and it seemed as if the very powers of darkness which war against the Saints were let loose upon me. But the Lord knew my faith, my zeal, my integrity of purpose, and he gave me the victory. I went to brother Joseph Smith in tears, and, with a broken heart and contrite spirit, confessed wherein I had erred in spirit, murmured, or done or said amiss. He frankly forgave me, prayed for me and blessed me. Thus, by experience, I learned more fully to discern and to contrast the two spirits, and to resist the one and cleave to the other. And, being tempted in all points, even as others, I learned how to bear with, and excuse, and succor those who are tempted. Late in July I arrived in the City of New York, on a mission, took lodgings, and commenced to preach and write. My first production in that city was a book of upwards of two hundred pages, entitled the "Voice of Warning." The first edition of this work consisted of four thousand copies; it has since been published and re-published in America and Europe, till some forty or fifty thousand copies have not been sufficient to supply the demand. Thousands date their conversion to the fullness of the gospel to the reading of that book.
