Apostles have seen the Savior, Jesus Christ, and their duty is to preach Christ to the world...
“I bear witness to you that those who hold the apostolic calling may, and do, know of the reality of the mission of the Lord” (Stand Ye in Holy Places , 64–65).
Apostles know for certain by personal revelation that Jesus is the Christ and that He lives as a resurrected being. The scriptures explain that “with great power gave the apostles witness of the resurrection of the Lord Jesus” (Acts 4:33).
President Joseph F. Smith (1838–1918) explained the sacred nature of their calling: “These twelve disciples of Christ are supposed to be eye and ear witnesses of the divine mission of Jesus Christ. It is not permissible for them to say, I believe, simply; I have accepted it simply because I believe it. Read the revelation, the Lord informs us they must know, they must get the knowledge for themselves. It must be with them as though they had seen with their eyes and heard with their ears and they know the truth.
That is their mission, to testify of Jesus Christ and Him crucified and risen from the dead and clothed now with almighty power at the right hand of God, the Savior of the world.
That is their mission, and their duty, and that is the doctrine and the truth that it is their duty to preach to the world and see that it is preached to the world” (in Conference Report, Apr. 1916, 6).
