Seed of the devil is about how mankind changed into the image of Satan after the fall.
Even now. Believers walking in their flesh will lie and maneuver to get our way to win an argument.
Besides...
How do you know what ran through Adam's mind after he ran and hid?
Do you?
Adam? Had no faith?
Then, why do we see why the Lord shedding the blood of animals as evidenced with the animal skins that the Lord provided for Adam and Eve to cover themselves with? God accepted their repentance for doing wrong.
Another thing.
Why do you need everything spelled out for you in black and white?
And this is my prayer: that your love may abound more and more in knowledge
and depth of insight, so that you may be able to discern what is best and may
be pure and blameless for the day of Christ, filled with the fruit of righteousness
that comes through Jesus Christ—to the glory and praise of God." Philippians 1:9-11
Insight does not appear in black and white.
Insight has been an ongoing part of the spiritual life of those who are growing in grace and understanding.
Jesus answered them, “Destroy this temple, and I will raise it again in three days.”
They replied, “It has taken forty-six years to build this temple, and you are going
to raise it in three days?” But the temple he had spoken of was his body." John 2:19-21
If someone like you been there?
He would have been demanding that someone explain,
"Where did he say it was about his body?"
We're all in the Bible.
Sometimes, it takes insight to see how.
