Adam eating the fruit triggered the fall. Eve could have eaten it all day and nothing did or would have happened. It was Adam who had dominion, not Eve. Adam should have rebuked her but ate it to please her.
Seems to me that Adam ate the fruit to please himself.
or alternatively, he could have rebuked the serpent for misquoting God. God did not say they could not “touch” the tree lest they would die... he said do NOT eat because it will kill you.
women were created a “weaker vessel” for the purpose of procreation. They are built such that they cannot do as much of some things strenuously whilst they bearing a child. Adam, doing his job correctly, would have stepped in to defend/protect Eve... Protecting her, would have caused him to be assessed as passing the test for both the male and female aspect of the one flesh couple at that point.
Eve was capable of being deceived. But Adam was NOT deceived and was IN the transgression... New testament says she WAS deceived... and points the finger of culpability directly at Adam. it is in ADAM that death from one passed to us all.
Adam being sinless, could have been a holy sacrifice in some manner... but we see that THE Lamb of God was slain before the foundation of the earth. PRIOR to the fall.
my very vain consideration since biblically the predetermination of God about the Lamb being slain in prehistory, is true... did Adam know THAT fact before he brought death to our species?
Did he know that when Satan approached Eve and her husband WITH her... in the garden. Scripture does not say. if essential for mankind... God would have told us somehow... maybe Adam was privy to some of the counsel of God, and the fall was a known part of the plan that Adam a role to play. God clearly planned for it, in the Word made flesh... God, the Son. Jesus loved being called the Son of Man.
Totally vain speculation and musings on my part. Still, it has implications about how we assume that we do so many things by “choice”.
