Immediately on receiving this revelation, preparations were made for the journey of the brethren therein designated, to the borders of the Lamanites, and a copy of the revelation was given them. They bade adieu to their brethren and friends, and commenced their journey, preaching by the way, and leaving a sealing testimony behind them, lifting up their voice like a trump in the different villages through which they passed. [13] They continued their journey until they came to Kirtland, Ohio, where they tarried some time, there being quite a number in that place and vicinity who believed their testimony, and came forward and obeyed the Gospel. Among the number was Mr. Sidney Rigdon, [14] and a large portion of the church over which he presided. {121} [Sidenote: Previous Relations of Pratt and Rigdon.] Previous to this, Elder Parley P. Pratt had been a preacher in the same church with Mr. Rigdon, and resided in the town of Amherst, Loraine county, in Ohio, and had been sent into the state of New York on a mission, where he became {122} acquainted with the circumstances of the coming forth of the Book of Mormon, and was introduced to Joseph Smith, Jun., and other members of the Church. The belief that there were many in the church with which he had formerly been united, who were honest seekers after truth, induced Elder Pratt; while on his journey to the west, to call upon his friends, and make known the great things which the Lord had brought to pass. [Sidenote: Presentation of the Book of Mormon to Sidney Rigdon.] The first house at which they called in the vicinity of Kirtland, was Mr. Rigdon's, and after the usual salutations, they presented him with the Book of Mormon, stating that it was a revelation from God. This being the first time he had ever heard of, or seen, the Book of Mormon, [15] he felt very much {123} surprised at the assertion, and replied that he had the Bible which he believed was a revelation from God, and with which he pretended to have some acquaintance; but with respect of the book they had presented him, he must say {124} that he had considerable doubt. Upon this, they expressed a desire to investigate the subject, and argue the matter. But he replied, "No, young gentleman, you must not argue with me on the subject; but I will read your book, and see what claims it has upon my faith, and will endeavor to ascertain whether it be a revelation from God or not."
