Well, the original question is different than this one. The original was: were Adam and Eve free to sin? They did sin, so that makes the answer obvious. They were free to sin; i.e., not prevented from sinning.
Did Adam and Eve have the possibility to not sin? The answer is yes. But it's my perspective. Yes, because God granted true, complete free choice.
like an alcoholic--"I can take it or leave it"---drowning!
When your in the trick box---jail...free doesn't exist!
Adam and Eve never had a chance---second chance yes...free No--never!
Realatarians believe only trouble is free---choose life-WORK(Christ)!
They were free to sin; i.e., not prevented from sinning.
free anything---especially right-righteousness---even grace is not free---the wheels of justice never cease--rest...
Yeah---free is cheap easy-grace...window dressings!
Where does the "prevention"--power come from?
