Brigham Young

We believe we are entitled to the gift of the Holy Ghost in extent according to the discretion and wisdom of God and our faithfulness; which gift brings all things to our remembrance, past, present, and to come, that are necessary for us to know, and as far as our minds are prepared to receive the knowledge of God revealed by that all-wise Agent. The Holy Ghost is God's minister, and is delegated to visit the sons and daughters of men. All intelligent beings pertaining to this earth are instructed from the same source. (Discourses of Brigham Young, pp.160-161)
