Never heard of that book, & yes, everything was very good, for what God had to work with, which was dust, that was made corrupt, so Adam was made with a glitch (for the want of another word) in him, ready to sin, hence the whole sovereign salvation plan of God. All worked out & predestined before the foundation of the world. Humans since Adam all have that same sinful nature, ready to sin, but its not original sin, as we are all responsible for own.
I can agree that reading a "gap" in between Gen 1:1-2...
which is basically saying that Gen 1:1 recalls an unspecified and potentially vast span of time prior to the onset of God's creative activity in the cosmos...
is very clever & insightful
However, while I acknowledge that Saint Augustine also read the angelic fall into verse 4 with the division of light from dark representing the expulsion of the dark fallen angels from the heavenly council... I cannot agree with that interpretation... given that God is still speaking with fallen angels including Satan in Job 1 & Psalm 82
I like the "gap" or "unspecified vast span of time" interpretation...
but cannot accept that God would survey His vast cosmic realm, including an ongoing Satanic rebellion against the same, and call it "all very good" (Gen 1:31) at the end of the 6th Divine Day...
and then "take a vacation" and rest for a 7th Divine Day (Gen 2:1-3)...
with an ongoing Satanic rebellion going on
Again, God made man then woman amidst a lush vegetative environment (Gen 1:26-30 = Gen 2:4-20) giving mankind permission to eat of every tree bearing seed (Gen 1:28 or so) but not the (seedless) Tree of Knowledge of Good & Evil (Gen 2:15 or so)...
that's all the same set of events told twice...
So we can read the ToKoG&E (Gen 2:15) into the 6th Divine Day account (Gen 1:28)...
but some time afterwards (Gen 1:31) everything was still so "all very good" that God chose to rest for an entire cosmic 7th Divine Sabbath Day (Gen 2:1-3)...
all before the
Nachash ("naga, snake") tempted Eve (Gen 3:1)
Please recall that the
Nachash ("naga, snake") of Gen 3 is described as a
Seraph ("serpent") in Isaiah 14 and as a guardian
Cherub ("cobra") in Eden in Ezek 28, evidently of the same class of beings as the
Cherub ("cobra") tasked to guard Eden after the fall
So, the "Snakey Serpentine Cobra" was in "Eden" as a powerful "guardian" of something... maybe the ToKoG&E ???
Everything was "very good" until one day "Eve" wandered past the "ToKoG&E" guarded by the "Snakey Serpentine Cobra"... who, evidently perceiving some sort of opportunity, recruited Eve to rebel against God's authority
Satan's rebellion began on earth, recruiting Eve on
earth to the rebellion (Gen 3) was the very first act, occurring long before Satan had recruited other angelic beings in the
heaven to assist him (Gen 6).
Both humans and the Adversary were cast out of Eden (Ezek 28 says "
were in Eden"), though humans remained on earth and the Adversary remained in heaven...until the Cross (Rev 12)
Now the Adversary has been cast out of Eden as well as heaven, and only has some residual influence on earth with & through those humans recruited to his cause...all of whom will eventually be torched at the 2nd Coming (Rev 20:9+)
