Some thoughts about eating apples.

After eating the apple, Adam and Eve realized they were naked.  At that point naked, which until then had not been an issue, was now an issue which brought guilt and shame.  An experience, which until that moment, had not existed.

Why put the tree there to begin with?  Perhaps because to be truly free you must first have a choice.

God knew they would fall and His plan of redemption was already at work.
