Exaltation-worthy men and women (i.e., the 144,000 Servants in John's vision)¹ receive the seal of the living God as they receive the temple sealing ordinance² and also have their calling and election made sure.³ This calling and election begins as a conditional promise of exaltation that many people received in the premortal existence.⁴ That same conditional promise is made again when worthy people receive their exalting ordinances in a temple of The Church of Jesus Christ of Latter-day Saints.⁵

When a conditional promise of exaltation becomes unconditional through righteousness,⁶ then a person's calling and election is said to be made sure.⁷ The unconditional promise is ratified by the Holy Ghost, acting in his capacity as the Holy Spirit of Promise.⁸ Saints that have their calling and election made sure receive the more sure word of prophecy,⁹ which is a confirmatory revelation that a person's calling and election has been made sure.¹⁰ Such persons are guaranteed exaltation¹¹ in the celestial kingdom.¹² They become members of the Church of the Firstborn,¹³ which consists of exaltation-worthy saints within the larger group of celestial-worthy (but unexalted) saints called the general assembly.¹⁴

Those that have their calling and election made sure are sometimes called heirs of salvation.¹⁵ This name, however, is often applied more generally to all people saved in any kingdom of glory, including the terrestrial and telestial kingdoms.¹⁶
