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 . . . 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. Joseph Smith ( DHC , Vol. 3, p. 380).
