That is not what the verse we are discussing says.
I want to discuss what is "literally" said but you do not. It does not say that "God did not know what Abraham was going to "actually" do until he was about to "actually" do it."
Instead it speaks about when God knew that Abraham had a fear or revererance of Him.
Now I will ask my question again and perhaps this time you will answer it:
Do you think that God did not know whether or not Abraham feared or reverenced Him until he stretched forth his hand and took the knife to slay Isaac?:
"And Abraham stretched forth his hand, and took the knife to slay his son. And the angel of the LORD called unto him out of heaven, and said, Abraham, Abraham: and he said, Here [am] I. And he said, Lay not thine hand upon the lad, neither do thou any thing unto him: for now I know that thou fearest God, seeing thou hast not withheld thy son, thine only [son] from me" (Gen.22:10-12).
If you are saying that this verse is about "when" God knew, then you are saying that God "did not know" until this moment "when" Abraham was about to kill Isaac. Right?
The answer to your question is "yes". I thought you would have understood that already. Apparently we both agree.
