Our eternal life is as dependent upon spiritual nutrients as our mortal life is upon air. The most important spiritual nutrients are knowledge of God and knowledge of his Son. We know the Father by knowing the Son. What is the best source on the face of the earth to learn about the Son? It is in studying another testament of him, commonly known as the Book of Mormon, and then having the Holy Ghost bear witness to you that it is true. – J. Thomas Fyans, “The Book of Mormon’s Witness of Jesus Christ,” Ensign (CR) May 1987
