"I declare unto you in all candor, and in all earnestness of soul, that I believe with all my heart in the divine mission of Joseph Smith, the Prophet, that I am convinced in every fiber of my being that God raised him up to restore to the earth the gospel of Christ, which is indeed the power of God unto salvation. I testify to you that Joseph Smith was instrumental in the hand of the Lord in restoring God's truth to the world, and also the holy Priesthood, which is his authority delegated unto man. I know this is true, and I testify of it to you. To me it is all-in-all; it is my life, it is my light; it is my hope, and my joy" (Teachings of Presidents of the Church: Joseph F. Smith, p. 18-19).
