Joseph Smith’s life from the early 1820s until the settlement at Nauvoo was turbulent, characterized by moving frequently, economic disasters, mob violence and the expulsion of the Church members from Missouri. The five year period during which he resided at Nauvoo was different. During this relatively safe and peaceful time, the Prophet refined LDS theology in several key areas: (1) Concepts of God and Man, (2) Man in the World, (3) Salvation for the Dead, (4) Eternal Nature of Priesthood Covenants, (5) Temple Ordinances for the Living, (6) Celestial and Plural Marriage, and (7) Eternal Progression.
