In the aftermath of her divorce from a covert narcissist, the author realized that there were two components to what she experienced: the intellectual, and the spiritual. While intellectual awareness provided understanding, healing came through submission and surrender to Jesus.
The reason why the Word of God is called the Sword of the Spirit is that it is the weapon that destroys evil in the spiritual realm. You also can move from understanding the traits and characteristics of covert narcissists to becoming strong and victorious in Christ.
Jesus wants you. He wants you to find peace in His presence. He wants to restore you, heal you, and bless you more than you can ever fathom. Give Him permission, and use His Word.
