I think we call it the Fall of Humankind because the first humans were at the pinnacle of human experience, where everything was good, their relationships were healthy and filled with love, their work was satisfying and productive, their resources were ample, the world was their oyster, and their spiritual communion with God and each other was full.
God would not leave Adam and Eve destitute. The promise God made in this chapter is called the proto-evangel, the first prophecy of the Messiah. Understanding Who the Messiah would be, and what He would do, was going to slowly unfold throughout the Old Testament. Then, throughout the New Testament, Who Jesus is and what He has done is revealed.
For the woman, the consequences would primarily affect her relationships. Interestingly, God said her pain would be increased, evidence that pain would have already existed, even in the perfection of Eden. We can learn that pain is not necessarily a bad thing, but could be a good thing, able to strengthen and deepen the man and the woman, and their relationship with each other, as well as with God. But now, that pain would be greatly increased.
Imagine the moment they entered the hushed glade where Life and Knowledge stood, in their quiet power. The Tree of Life, he told her. We may eat of all the trees in the Garden, including this tree. But already she was looking at the other, beguiling, Tree, spellbound by its exotic loveliness, its alluring fragrance redolent with rare spices, sharp and tangy, the perfume of hidden mysteries.
The woman must have felt both the strong pull of the Tree itself, and her own fascination with the secret promises it seemed to hold. Temptation had found a hook in her heart, and the pull was strong. To combat its magnetic draw, the woman drew from God’s words for help. But the words she held onto were not simply God’s words, but an added word. To God’s Law had been added something a little extra. Oral Law.
