Brigham Young,
Journal of Discourses — Volume 15…
“ We have the testimony of all this for ourselves.How are you going to know whether this work is true, whether the Bible is true, whether Joseph was a Prophet, whether Jesus was the Savior, and his Apostles were correct in their teachings? There is no way for you and me to know these things but by the Spirit of God; and if we live so as to enjoy the light of that Spirit, the light of revelation, it will be in us like a well of water springing up to everlasting life. If we do not live thus, we are in the dark as well as they.All religion is a mystery. ”
