Actually, God in His mercy gave Adam every opportunity to repent and ask for forgiveness. The real sin of Adam is not that he and Eve were foled by the cunning Serpent, but that Adam blamed God for his sin. He could have repented but he chose not to.
"Humans can say "no" to evil, but they don't. In doing that, they re-invent evil every time"
" The real sin of Adam is not that he and Eve were foled by the cunning Serpent, but that Adam blamed God for his sin"
The sin of Adam was the same sin Lucifer/Satan committed, he wanted to be like God and decide what was best for himself; the sin of idolatry, graven image, blasphemy all wrapped in presumption. Every time we sin we commit the same sin over again, we re-invent nothing. There has not been a "new" sin invented since Lucifer/Satan's. It's boring, all we do is figure out ways to package it.
Repentence has nothing to do with the transaction in the garden. When Adam sinned the whole race and creation was infected. Only his death could have paid the penalty for his sin and then God would have had to start over again and Lucifer/Satan would have won. Instead He provided the sacrifice for sin and doomed the enemy.
Interesting, it was God who allowed Lucifer/Satan into the garden to tempt Adam during this probationary period of innocence, much like He did with Job. For even after Lucifer's fall he was still subject to God and could only do what God allowed.
