In the Garden of Eden where food was abundant, a specious quest for “more” was thought to be satisfied, apart from God; “When the woman saw that the fruit of the tree was good for food and pleasing to the eye, and also desirable for gaining wisdom, she took some and ate it. She also gave some to her husband, who was with her, and he ate it.” ~Genesis 3:6
Just as the Y-Chromosome is passed down directly from a father to all of his sons and remains relatively unchanged throughout the generations, humanity can't go back to Eden and reverse the curse that was brought on all mankind; we are all born with this 'curse,' a.k.a. 'sin nature.'
Throughout history, God set about reassuring his people that he is sufficient to fulfill our deepest desires for “more.” “Taste and see that the LORD is good;” ~Psalm 34:8
Jesus' words were perhaps the most confusing and startling when he said, “Whoever eats my flesh and drinks my blood has eternal life,” ~John 6:54 http://www.desiringgod.org/blog/posts/what-jesus-meant-when-he-said-you-must-eat-my-flesh
The only way to reverse the curse is to believe in God's plan for our salvation and find our sufficiency in Christ Jesus, who came to earth as God in the flesh. By being born of a virgin, Jesus bypassed the sinful genetic line of Adam and that's why he is the only one who can offer all of mankind a new life for everyone who believes in him. We can all be, “Born Again.”
