spirit of prophecy (Brigham Young)
A brother on my right told you his experience, that there is no necessity for taking any man’s word for the truth of your religion; for it is the privilege of all to have the testimony of Jesus—to have the Spirit of prophecy. I have no greater privilege to enjoy the Spirit of prophecy than you have. I have no better right to the Holy Ghost than you. If you will live as you are taught, you will walk in darkness no more, but will walk in the light of life.
Brigham Young, Journal of Discourses 8:33
