Spencer W. Kimball
"While we lack recollection of our pre-mortal life, before coming to this earth all of us understood definitely the purpose of our being here. We would be expected to gain knowledge, educate ourselves, train ourselves. We were to control our urges and desires, master and control our passions, and overcome our weaknesses, small and large. We were to eliminate sins of omission and of commission, and to follow the laws and commandments given us by our Father" (Teachings of Presidents of the Church: Spencer W. Kimball, p. 3).
