Heber C. Kimball offers sermon on theology of being sealed to eternal life.
Heber C. Kimball, "Iniquity,"October 6, 1855, in Journal of Discourses, 26 vols. (Liverpool : Orson Pratt, 1856), 3:124
Some will come with great zeal and anxiety, saying, “I want my endowments; I want my washings and anointings; I want my blessings; I wish to be sealed up to eternal lives; I wish to have my wife sealed and my children sealed to me;” in short, “I desire this and I wish that.” What good would all this do you, if you do not live up to your profession and practice your religion? Not as much good as for me to take a bag of sand and baptize it, lay hands upon it for the gift of the Holy Ghost, wash it and anoint, and then seal it up to eternal lives, for the sand will be saved, having filled the measure of its creation, but you will not, except through faith and obedience.
