The woman said to the serpent, "We may eat fruit from the trees in the garden, but God did say, 'You must not eat fruit from the tree that is in the middle of the garden, and you must not touch it, or you will die.'"
"You will not surely die," the serpent said to the woman. "For God knows that when you eat of it your eyes will be opened, and you will be like God, knowing good and evil."
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. Then the eyes of both of them were opened, and they realized they were naked; so they sewed fig leaves together and made coverings for themselves.
Today as I bit into the first pleasing fruit from our little apple tree I thought that I might be in heaven. Then I realized I was standing in the middle of the chicken yard and was far from heaven. However, I can't get over how gorgeous the few fruit that I was able to pick are and just how amazingly perfect they grow. I don't really know, but my prediction is that the tree of knowledge in the middle of the Garden of Eden was definitely an apple tree. They are such a fabulous piece of fruit bringing knowledge to those that eat them. At times I wish we could all live like Adam and Eve, completely innocent and naked. But we're not; and you can read about the rest of the fall of man here.
I think I'd eat that fruit too.
