Peter taught that he had received what he called “a more sure word of prophecy” (2 Peter 1:19). The Prophet Joseph Smith defined what this term means: “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). On another occasion, the Prophet Joseph Smith instructed further: “I would exhort you to go on and continue to call upon God until you make your calling and election sure for yourselves, by obtaining this more sure word of prophecy, and wait patiently for the promise until you obtain it” (in History of the Church, 5:389).
