What does Satan try to achieve by neutralizing the Body of Christ?
Satan tries to neutralize the Body of Christ so that it says nothing and offers no opposition, because the Church is where he faces his greatest resistance. If silenced, he can gain full sway and freely promote deception, including another Jesus, another spirit, and another gospel.
Les explains that Eve is a symbol of the Church, the Body of Christ, so it is the Church that Satan constantly attacks. He knows that his greatest opposition is in the realm of the Church. Therefore, if he can neutralize the Body of Christ so that it says nothing, then he can have full sway. Les connects this to II Corinthians 11, where the serpent beguiled Eve through his subtlety so that minds could be corrupted from the simplicity that is in Christ, and warns of another Jesus, another spirit, and another gospel being preached.
