The serpent said confidently, "God knows that when you eat of it your eyes will be opened, and you will be like God, knowing good and evil.” As is his custom, he cloaks his lies with partial truths. On one hand, he told the truth in that their 'eyes woud be open' and they would be 'like God, knowing good and evil.' This half truth hid the reality that they would be introduced to an experience God, the creator, never intended.
The cunning of the enemy caused Eve to think she was supposed to be different and to have more than her designer had allowed. In her desire for more she forgot what she already had.
She was already like God.
She already knew good - and for that fact, that's all she was supposed to know.
She was exactly who she was supposed to be.
And yet, when she ate of the forbidden fruit, her 'eyes were opened.' She saw things differently. Her worldview and perspective was altered. This part of the 'fall out' opened her up to a different life. Now, it wasn't ONLY good. It was marked by good AND evil, hope AND hopelessness, life AND death.
She could see...but now she could see what she was not intended to see.
Now she could see...but it would cause her to be blinded at the same time.
The writer says, "their eyes were opened and they knew that they were naked." This new vision revealed a reality that was always there but wasn't supposed to be the focus of human experience.
Unfortunately this meant that they would see things they weren't created to take in.
Remember, when God gives us a command, it is ALWAYS given to protect our blessings.
