Because of the Fall, we were enabled to come into mortality. By following God’s plan of salvation and because of the Atonement of Jesus Christ, we are able to overcome the effects of the Fall (physical and spiritual death) and can have eternal happiness, joy, and exaltation.
2 Nephi 2:25
25 Adam fell that men might be; and men are, that they might have joy.
President Wilford Woodruff said:
“The world, more or less, has found a great deal of fault with Mother Eve and with Father Adam, because of the Fall of man; what I have to say with regard to it, I express as my own opinion. Adam and Eve came to this world to perform exactly the part that they acted in the Garden of Eden; and I will say, they were ordained of God to do what they did, and it was therefore expected that they would eat of the forbidden fruit in order that man might know both good and evil by passing through this school of experience which this life affords us. That is all I want to say about Father Adam and Mother Eve. Adam fell that man might be, and men are that they might have joy; and some have found fault with that.”
