Yeah, you'd better watch out - this god really means business when he says you'll die! Adam only got to live 930 after god told him he'd die - so WATCH IT!
He did die, as God said he would.
Were you there in the Garden? Were you God? Do you know what God was thinking or Adam?
In Genesis 3 we see why Adam died that day both spiritually and physically.
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.In the earlier chapter Adam and Eve given the right to eat from the tree of life.
In Genesis 3 it was taken away. So he died that day because the one thing that would keep him alive was removed from him.
So he slowly died and he finally did.
Die, die is the Hebrew wording.
