When faith is sufficient to sacrifice all earthly things, even life itself if necessary, it is possible for a person to know that he is accepted of the Lord for what he has done, and with this strong faith he may eventually receive eternal life.
Thus the Prophet Joseph said:
“After a person has faith in Christ, repents of his sins, and is baptized for the remission of his sins and receives the Holy Ghost, (by the laying on of hands), which is the first Comforter, then let him continue to humble himself before God, hungering and thirsting after righteousness, and living by every word of God, and the Lord will soon say unto him, Son, thou shalt be exalted. When the Lord has thoroughly proved him, and finds that the man is determined to serve Him at all hazards, then the man will find his calling and his election made sure.” (Teachings, p. 150.)
Such a person eventually receives godhood and becomes a member of the “church of the Firstborn.” (D&C 76:54.)
Who were some of the saints who were accepted of the Lord through their sacrifices? The Prophet Joseph Smith indicated that when a person has been proved of the Lord by “hungering and thirsting after righteousness, and living by every word of God,” he may then have the privilege of receiving the Second Comforter. This Comforter is the presence of the Lord Jesus Christ, “and the visions of the heavens will be opened unto him, and the Lord will teach him face to face.” Joseph Smith went on to say that this was the condition of a number of the ancient saints, naming Isaiah, Ezekiel, John the Revelator, Paul, and “all the saints who held communion with the general assembly and Church of the Firstborn.” (See Teachings, pp. 150–51.)
The assurance of being accepted of the Lord was also known to many of the Nephites: Enos (see Enos 1:27), Alma the Elder (see Mosiah 26:20), the Three Nephites (see 3 Ne. 28:4–11), and others (see 3 Ne. 28: 1–3).
The promise of becoming a member of the church of the Firstborn is also made to Latter-day Saints. (See D&C 76:50–60.) In our dispensation many Saints have made their calling and election sure. (See, e.g., D&C 124:19.) Noteworthy among these was William Clayton, to whom the Prophet said:
