Blessing nine: We have power to make our calling and election sure, so that while we yet dwell in mortality, having overcome the world and been true and faithful in all things, we shall be sealed up unto eternal life and have the unconditional promise of eternal life in the presence of Him whose we are.

Our revelations say: The more sure word of prophecy means a man’s knowing that he is sealed up unto eternal life, by revelation and the spirit of prophecy, through the power of the Holy Priesthood. (D&C 131:5.)

During the latter years of his ministry, in particular, the Prophet Joseph Smith pleaded fervently with the Saints to press forward in righteousness until they made their calling and election sure, until they heard the heavenly voice proclaim: “Son, thou shalt be exalted.” (Teachings of the Prophet Joseph Smith,, p. 150.)

He himself became the pattern for all such attainment in this dispensation, when the voice from heaven said to him: “I am the Lord thy God, and will be with thee even unto the end of the world, and through all eternity; for verily I seal upon you your exaltation, and prepare a throne for you in the kingdom of my Father, with Abraham your father.” (D&C 132:49.)
