God had WARNED them, then Passed Sentence on them when they rebelled.~
<snip>
Nothing ANYWHERE in the Bible mentions or even hints at them being forgiven.
Something to perhaps consider: As part of their "sentence", they were cast out of the garden.
Cursed was the ground, in toil should they eat, thorns and thistles, by the sweat of their face would they eat bread, until they returned to the ground.
They were "sentenced", they served that "sentence".
Did they go directly to "heaven"? Not in my opinion.
Did they go to "hell"? Not in my opinion.
Did they go unto a place of holding? In my opinion, yes. Cf Luke 16; Enoch 22
As to which place of holding, that would be entirely up to them, and how they lived the rest of their lives. Something we are not told. Assuming they sought good and did well, the one likened to Abraham's bosom, for they served their "sentence".
We don't know really what happened in the lives of Adam and Eve, how they spent the rest of their days. Our best guess IMO, is that they also may have been a part of those when "Jesus" preached to the "spirits" in prison.
OTOH: They also walked and talked with 'Elohim. How did it go for those who were a part of the Exodus and witnessed the mighty hand of 'Elohim and sinned? For the fate of those, would have been different than the fate of those in the days of Noah before the flood.
Personally, I think they served their sentence, and went to a place of holding. To argue it, is pointless from my perspective. But hey, what do I know.
