"Salvation in its true and full meaning is synonymous with exaltation or eternal life and consists in gaining an inheritance in the highest of the three heavens within the celestial kingdom.... Salvation in the celestial kingdom of God, however, is not salvation by grace alone. Rather, it is salvation by grace coupled with obedience to the laws and ordinances of the [Mormon] gospel."
