Mormonism teaches that the consequence of the Fall is that Adam and Eve were separated from God, which is referred to as spiritual death and they became mortal beings, subject to physical death. The LDS Church believes this act of transgression is a blessing and an integral part of Mormon theology.
“In addition to introducing physical and spiritual death, [the Fall] gave us the opportunity to be born on the earth and to learn and progress. (True to the Faith, p. 57)
According to Mormonism, the greatest blessing from the Fall is that Adam and Eve became mortal. Even though mortality means physical death, Mormonism emphasizes their teaching that mortality includes Adam and Eve’s ability to have physical children.
“If Adam had not transgressed he would not have fallen, but he would have remained in the garden of Eden. And all things which were created must have remained in the same state in which they were after they were created; and they must have remained forever, and had no end. And [Adam and Eve] 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. But behold, all things have been done in the wisdom of him who knoweth all things. Adam fell that men might be; and men are, that they might have joy.” (2 Nephi 2:22-25, The Book of Mormon)
Heavenly Father gave a choice to Adam and Eve to obey or disobey His command to not eat the fruit from the tree of knowledge. Mormonism teaches that Adam and Eve exercised their agency correctly. Even though they disobey God’s command, they instead, obeyed God’s other command to be fruitful and multiply. Since Adam and Eve were immortal beings on earth, they could not have any children. After the Fall, they received the curse of spiritual death by being separated by God. They also received the curse of physical death from which they received a mortal body. This curse is a blessing by Mormonism for it becomes a central point to the LDS plan of salvation.
As a result of the Fall, Mormonism teaches that worthy spirit children from the pre-mortal world now have the opportunity to be born from mortal parents. In their human, mortal condition, they have the opportunity to fulfill their divine potential (see Exaltation). By overcoming the tests of life and conquering sin through obedience, a Mormon can fulfill Heavenly Father’s plan of salvation. Since there is a strong emphasis on family in the LDS Church and the desire to have an eternal family, Mormons express gratitude for the Fall since they can now receive the blessing of family.
Biblical Christianity teaches:
The Fall is not a good thing because sin caused separation from God. Adam and Eve had the ability to obey God, but they chose to disobey and received condemnation from Him. As a result, all humans are born into sin. By nature, people are spiritually dead and cannot become righteous on their own. Jesus came to rescue people from our sinful condition by being our substitute on the cross.
