Satan wanted Eve to believe he was right and God was wrong and to make her own decision, thinking that she would be right as well. Being independent often means being apart and alone to oneself. This is where Eve found herself when the jig was up. Thinking independently of God's thinking does that. Pride strikes deeply at the central spiritual nervous system, making it difficult to respond coherently, according to the Word of God, against an attack from any sin-virus.
Pride IS the venom of the serpent.
His Own people who are free to think WITH God, not apart from God. One can be independent and not be free. In Jesus, we are free from sin, from the rudiments of man and his perversion of God's laws. If what you hear conflicts the Word of God, it isn't God saying it. If what you do in the name of the Lord brings you condemnation, it isn't God ordaining it.
