“A person may profit by noticing the first intimation of the spirit of revelation, for instance, when you feel pure intelligence flowing into you, it may give you sudden strokes of ideas, so that by noticing it, you may find it fulfilled the same day or soon; (i.e.) those things that were presented unto your mind by the Spirit of God will come to pass; and thus by learning the Spirit of God and understanding it, you may grow into the principle of revelation until you become perfect in Christ Jesus.” Joseph Smith, History of the Church, 3:381
“Many men will say, “I will never forsake you, but will stand by you at all times.” But the moment you teach them some of the mysteries of the Kingdom that are retained in the heavens and are to be revealed to the children of men when they are prepared for them they will be the first to stone you and put you to death. It was this same principle that crucified the Lord Jesus Christ, and will cause the people to kill the prophets in this generation.” Joseph Smith (History of the Church 5:424)
“God hath not revealed anything to Joseph, but what He will make known unto the Twelve, and even the least Saint may know all things as fast as he is able to bear them.” Joseph Smith, Teachings of the Prophet Joseph Smith, pg. 149.
