"Doctrine and Covenants, 135:4"

“That which is wrong under one circumstance, may be, and often is, right under another. God said, 'Thou shalt not kill'; at another time He said, 'Thou shalt utterly destroy.' This is the principle on which the government of heaven is conducted—by revelation adapted to the circumstances in which the children of the kingdom are placed. Whatever God requires is right, no matter what it is, although we may not see the reason thereof till long after the events transpire.'”

“Would to God, brethren, I could tell you who I am! Would to God I could tell you what I know! But you would call it blasphemy, and there are men upon this stand who would want to take my life.”

“More quotes from Joseph Smith Jr.”

“A man is saved no faster than he gets knowledge.”

“You have to learn how to be Gods yourselves, and be kings and priests to God, the same as all Gods have done before you, namely by going from one small degree to another, and from a small capacity to a great one: from grace to grace FROM EXALTATION TO EXALTATION until you ATTAIN THE RESURRECTION OF THE DEAD.”

“Take away the Book of Mormon and the revelations, and where is our religion? We have none.”
