When God cursed the woman…
the curse was specifically on her reproduction saying that her conception would be in sorrow and childbirth would be in pain. In this article, I would like to place a hypothesis that would explain what could have been the biological changes happened in the female when God cursed her.
Genesis 3:16 (NKJV)
16 To the woman He said: “I will greatly multiply your sorrow and your conception; In pain you shall bring forth children; Your desire shall be for your husband, And he shall rule over you.”
One of the main reasons for problems in pregnancy is PCOS (Polycystic ovaries syndrome) and one of the major causes for PCOS is the overexpression of androgens (male hormones).
So, I strongly believe that when God cursed the woman, the change that occurred in the woman is the change in the genes that are responsible for the expression of male hormones that led to the overproduction of male hormones.
When God cursed the man…
the curse was related to his job making it hard and even after his hard work, the fruit of it would not be enough and not the one he wanted. He should earn with sweat of his face; meaning he has to use his muscles a lot to earn.
Genesis 3:17 (NKJV)
17 Then to Adam He said, “Because you have heeded the voice of your wife, and have eaten from the tree of which I commanded you, saying, ‘You shall not eat of it’: “Cursed is the ground for your sake; In toil you shall eat of it All the days of your life.
18 Both thorns and thistles it shall bring forth for you, And you shall eat the herb of the field.
19 In the sweat of your face you shall eat bread Till you return to the ground, For out of it you were taken; For dust you are, And to dust you shall return.”
So, I say that when God cursed the man, it was directed at his sixth sense. (You have to read the article on “God’s Will” to understand this).
I say that it was directed at his sixth sense because it is where he gets the ideas from; which would enable him to be successful in what he does. Moreover, The Bible says that God is the one who gives ideas. When God cursed the man, he lost his relationship with God which eventually led him depriving of his ideas of success in life. So, after the fall, he relies only on his muscle power instead of having free flowing ideas. The reason why God’s curse was directed at his sixth sense is because earlier (before fall), that (sixth sense) was his unique and greatest blessing from God.
