Read Genesis 1:9,16,17 and 3:6,22-24 and Rev. 22:2,14.
The forbidden fruit of the Garden of Eden, spoken of in the Scriptures, was not an apple. Sorry to burst your bubble. You may have seen artist's pictures of red fruit, learned about Adam's apple, (supposedly stuck in every man's throat) and heard lyrics like, "Eve tempted Adam with an apple", and may even have heard it from Sunday school teachers, but it's not true. How do we know? Go to the Scriptures.
First of all, Adam and Eve could eat of every tree in the Garden, except one. It wasn't the apple tree. It was the Tree of the Knowledge of Good and Evil. It was one of two unique trees in the Garden of Eden, and it was the only one of its kind, and located only in Eden, which is now hidden from us.
Further, once they ate of it, were judged by God and banished from Eden forever, its fruit was never eaten again, unlike the apple tree.
Also, the fruit is not decribed for us, except to say that it was good for food, pleasant to the eyes, and desirable to make one wise.
Notice that the Tree of Life, also another unique tree in the midst of the garden, was not forbidden to Adam and Eve. Ever wonder why they didn't eat from that one, instead? We'll never know.
But at least we know that in the New Jerusalem we will have access to the Tree of Life, forbidden to our first parents because of their disobedience.
