(1) They were clear in knowing that God commanded them not to eat the fruit and that they would die if they did. That should've been plenty enough of information for them to obey.
What did they know of death?
I don't think they understood. This was demonstrated in the discussion with the serpent.
--- PARODY ---
Serpent: Did God really say... ?
Eve: He said don't eat and don't touch.
Adam: Oops, my bad, I said don't touch.
Eve: What?! God didn't say that? !!!
Adam: No, I added that because
I know you like to touch things without thinking.
Eve: So, you don't trust me? !!!
Adam: I'm looking out for our best interests. My job.
Eve: I see.
Serpent: Are you going to eat, or not? !!!
Eve: Let me check with the boss. - LOL
Adam: Scram serpent!
Serpent: Hiss... (walks away dejected)
Eve: Hey, let's check out that other tree.
Adam: Good idea!
Indeed.
(2) They didn't have to know all that Satan had planned; they only had to know that their disobedience had dire consequences.
Did they?
God told Adam and Adam told Eve. (with seeming misinformation included)
(3) You and I don't know what they knew and didn't know. We can't infer anything from the silence of Scripture.
True. But where does that leave us?
(4) Eternal punishment is consistent with God's quality of justice, which is also eternal along with his love. We don't know whether or not Adam and Eve were saved after that. That's up to God.
Quality of justice? Eternal torment for a temporal transgression? Where's the quality in that?
Even humans have laws against cruel and unusual punishment. A state of eternal burning is about as cruel as it can get.
Thankfully, humans are incapable of that level of torture. The church used burning at the stake to hurry up God's "justice".
What is the source of salvation?
I enjoy our conversation. I hope we can do more conversing in the future.
Thanks. I'm open to that.
I do weigh online relationships though. At the point that it seems fruitless I back away.
(and all too often WAY beyond the point...) LOL
