Distinct from immortality. It doesn’t describe living eternally with God but *living eternally as God*. Thus, it is another name for godhood and synonymous with exaltation. “Eternal life, or exaltation, is to inherit a place in the highest degree of the celestial kingdom” (True to the Faith, p. 52). It can only be achieved “through obedience to the laws and ordinances of the Gospel” (Ibid. p. 52).
Biblical Christianity teaches that eternal life is *living with God*. It is his gift (Romans 6:23) and is received the moment a person is brought to faith (John 5:24).
