Joseph Smith

“O ye Twelve! and all Saints! profit by this important Key---that in all your trials, troubles, temptations, afflictions, bonds, imprisonments and death, see to it, that you do not betray heaven; that you do not betray Jesus Christ; that you do not betray the brethren; that you do not betray the revelations of God, whether in the Bible, Book of Mormon, or Doctrine and Covenants, or any other that ever was or ever will be given and revealed unto man in this world or that which is to come” (Teachings of Presidents of the Church: Joseph Smith, p. 66).
