Joseph Smith taught, "Adam was made to open the way of the world" (Teachings of the Prophet Joseph Smith [Salt Lake City: Deseret Book Press, 1938], p. 12). After creating the earth and Adam and Eve, God created a garden for Adam and Eve to live in. Two trees were placed in the midst of the garden : the tree of life and the tree of knowledge of good and evil. To Adam and Eve, God said: "Of every tree of the garden thou mayest freely eat, But of the tree of the knowledge of good and evil, thou shalt not eat of it, nevertheless, thou mayest choose for thyself, for it is given unto thee; but, remember that I forbid it, for in the day thou eatest thereof thou shalt surely die" (Moses 3:16-17). Though it was forbidden by God (Moses 3:16-17), it was necessary for Adam and Eve to eat the fruit of the tree of knowledge of good and evil. By eating the fruit, the Fall was brought about. And the Fall initiated mortality.
The Garden President Ezra Taft Benson taught: "Just as a man does not really desire food until he is hungry, so he does not desire the salvation of Christ until he knows why he needs Christ. No one adequately and properly knows why he needs Christ until he understands and accepts the doctrine of the Fall and its effect upon all mankind" (Conference Report, Apr. 1987, 106-107; or Ensign, May 1987, 85).
