The Importance of the Historical Adam

Read the text. The context is clear. The eating of the fruit causes Adam to be afraid of God.The very next chapter describes the first murder, that too of a sibling. And then it just gets worse from there. It’s obvious human beings could not handle the knowledge of good and evil.

They were given a clear instruction to not eat from the tree. It was simple matter of obedience.
The “law” provides a limited understanding of good and evil. It’s good to eat of any other tree… evil to eat the fruit of this particular tree.

Where did you get this understanding? I spoke about the incarnation, not the sacrifice on the cross. The incarnation involves a man living without Sin in perfect obedience to God.
Only God could have done this.
The sacrifice is about Jesus representing/taking responsibility for humanity. That’s why one needs to acknowledge Jesus as Lord and master to receive the benefits of the cross.
It’s not a matter of God being pissed off and taking it out on himself.
If you don’t belong to Jesus, your sins remain and so does God’s wrath.
The point of the cross is to bring humanity (those who are willing) into union with God in Christ Jesus.

I am not removing God’s agency. Being cast out of the garden is a judgement of God.

Where did God say the tree was poisonous? You are reading that into the text.
God said they would die if they ate of the tree and it did happen.

That’s a wierd accusation. I have answered your questions.
