God's definition of "death" is separation from Him.
You are making the HUGE mistake of thinking that Adams fall is the "future/eternal death".
This only happens after the GTW judgement in the lake of fire.
This is DEFINTELY not the case today, despite the inane ignorant ravings of the Calvinites.
We living souls are NOT created "eternally dead", already condemned.
And if we were already condemned at birth, Christ would have come in vain,
because it would have been too late as the FINAL JUDGEMENT WOULD HAVE ALREADY BEEN RENDERED!
And FINAL JUDGEMENT has NOT yet been rendered. It is yet future. Get it?
Christ came to give us RENEWED life, eternal life, abundant life, and reverse the curse.
This is definitely possible under the present state of circumstances of man.
Adam was separated, yes. But only by degrees. Not completely, not permanently.
Why? Because the Bible makes clear that Adam was a "special case". Thats why.
His sacrificial love being the crucial factor.
I mean God is certainly on speaking terms with mankind right?
Adam did not keel over after he ate the fruit right?
Adam was not cast immediately into the lake of fire right?
God was interacting with Adam and Eve and their progeny post fall right?
God has made covenants with men right?

And AGAIN, the clueless Calvinites got all of this "spiritually dead" business ALL WRONG man.
They get it all wrong I'm telling you.
