Gospel Doctrine, pg. 481; “The work in which Joseph Smith was engaged was not confined to this life alone, but it pertains as well to the life to come, and to the life that has been. In other words, it relates to those who have lived upon the earth, to those who are living and to those who shall come after us. It is not something which relates to man only while he tabernacles in the flesh, but to the whole human family from eternity to eternity.”
Ephesians 1:5-6; “Having predestinated us unto the adoption of children by Jesus Christ to himself, according to the good pleasure of his will, 6 To the praise of the glory of his grace, wherein he hath made us accepted in the beloved.”
Well Smith’s work obviously cannot be associated with anyone before he began his “work”. Certainly, his “legacy” will continue on as long as Mormonism is on the face of the earth.
