About this time Smith had a remarkable vision. He pretended that, while engaged in secret prayer, alone in the wilderness, an "angel of the Lord" appeared to him, with the glad tidings that "all his sins had been forgiven," and proclaiming further that "all the religious denominations were believing in false doctrines, and consequently that none of them were accepted of God as His Church and Kingdom;" also that he had received a "promise that the true doctrine and the fullness of the gospel should at some future time be revealed to him. Following this, soon came another angel, (or possibly the same one,) revealing to him that he was to be "the favored instrument of the new revelation;" "that the American Indians were a remnant of the Israelites, who, after coming to this country, had their prophets and inspired writings; that such of their writings as had not been destroyed were safely deposited in a certain place made known to him, and to him only; that they contained revelations in regard to the last days, and that, if he remained faithful, he would be the chosen prophet to translate them to the world."
