of salvation as explained above relies upon Christ's grace through His infinite atonement, and is conditional upon each person's eventual acceptance of Jesus Christ as their personal Savior from the consequence of sin and spiritual death. Through His physical and spiritual suffering in the Garden of Gethsemane and on the cross, He makes it possible for each person to be made clean from the metaphorical stains of human imperfections, and justifies and sanctifies each righteous person for admission into the glory that they have merited as they come unto Him with "full purpose of heart." Outer Darkness is reserved for those people who, after gaining a full knowledge of the Gospel, willfully deny and contend against the Holy Ghost. (Satan, his followers from the premortal life, and those who were born on earth but chose to become sons of perdition.) These individuals who inherit no glory are called sons of perdition. Although resurrected, and thus immortal, they willfully rebelled and rejected the right to salvation. Hypothesized influence of Emanuel Swedenborg Historian D. Michael Quinn in his book Early Mormonism and the Magic World View, has speculated that various parts of the plan of salvation were taken by Joseph Smith from Emanuel Swedenborg's book Heaven and Hell. In the book, Swedenborg wrote that "There are three heavens" that are "entirely distinct from each other." He called the highest heaven "the Celestial Kingdom," and stated that the inhabitants of the three heavens corresponded to the "sun, moon and stars." Swedenborg's book also mentions a veil, spirit prison and celestial marriage. Quinn further argues that the book was available to Smith, and that he was familiar with it. One account claims that Smith told Latter Day Saint convert from Swedenborgism Edward Hunter that "Emanuel Swedenborg had a view of the world to come, but for daily food he perished." Additionally, Quinn asserts that the book was in the Palmyra public library beginning in 1817, and that "[n]ine miles from Smith's farm, in 1826 the Canandaigua newspaper also advertised Swedenborg's book for sale. The bookstore offered Swedenborg's publications for as little as 37 cents." Historian Richard Bushman argues that it was more likely that both Swedenborg and Smith were influenced by New Testament scriptures that refer to "celestial" and "terrestrial" bodies that are compared to the sun, moon, and stars, noting fundamental differences between Smith's and Swedenborg's versions of heaven. Bushman also notes similarities
