Doctrines of Salvation 1:114; “The fall of man came as a blessing in disguise, and was the means of furthering the purposes of the Lord in the progress of man, rather than a means of hindering them.” – Joseph Fielding Smith
2 Nephi 2:23, 25; “And they would have had no children; wherefore they would have remained in a state of innocence, having no joy, for they knew no misery; doing no good, for they knew no sin. 25 Adam fell that men might be; and men are, that they might have joy.”
