“I can bear testimony that the gospel of Jesus Christ is true, and the word of the Lord, whether written or spoken, is true.
“Permit me to ask a question. Who are the individuals upon the face of the earth that can make this statement in truth? Who are the individuals that can say that the gospel of Jesus Christ is true and that he lives? Can the Christian World? They cannot. They may say they believe and have all confidence that Jesus lives; they may have all confidence in declaring that the gospel of Jesus Christ is true; they may firmly declare that the Bible (referring particularly to the New Testament) is true; that therein contained is the plan of salvation, and (that it) is true. This they may declare in all good conscience and with all soberness.
“But let me ask, Where are the individuals that can say that they know that Jesus lives? And who are the individuals that can say that his gospel is true and is the plan of salvation to man? I will let Christendom answer this question for themselves; but to me it is certain, that no man lives on the face of the earth, no woman lives, that can say this, except those to whom Christ has revealed himself. (1 Cor. 2:1–16; 1 Cor. 12:3)
“Though others may say in all good conscience they believe he lives—who knows the doctrine of the Lord Jesus Christ to be true? There is one class of people, and one only, that live upon the face of the earth, who do know it; and that class of men and women are those that keep his commandments and do his will; none others can say it. None others can declare with boldness, and emphatically, that Jesus lives and that his gospel is true.” (Joseph Fielding McConkie, Journal of Discourses Digest (Salt Lake City: Bookcraft, 1975), pp. 52–53.)
