Adam died spiritually? That is not scriptural. That is a definition given to it by man to appease himself. i.e. "the day you eat of it you will surely die."
so is it then the day the he will die, or is it the day where he will SURELY die? Let us appeal to scripture:
Genesis 3:22, 23 KJV
22 And the Lord God said, Behold, the man is become as one of us, to know good and evil: and now, lest he put forth his hand, and take also of the tree of life, and eat, and live for ever:
23 Therefore the Lord God sent him forth from the garden of Eden, to till the ground from whence he was taken.
So in verse 22 we see clearly that if God had NOT cast Adam and Eve out of the garden, they could have both lived forever AND known good from evil.
in Revelation, Jesus says "...and I will give to him permission to eat from the tree of life..." i.e. humanity restored to its original condition, where "the former things will be remembered no more," i.e. we will have no KNOWLEDGE of the former things, which are of course contemporary to us.
We can then conclude, that the death was caused by the revocation of permission to eat of the tree of life, NOT by the eating of the fruit of the knowledge of good and evil. There is no wriggle room.
