No she's not. She's trying to control her behavior by the power of God's presence by His Spirit. We're all learning to walk by the Spirit, not learning to walk by our own power. She's keenly aware that she has not the power in and of herself to do right.
Correct, she is not a murderer. But when/if she hates she has the spirit of murder in her, just as the lusting person has the spirit of adultery in them. But certainly, those things are not what she longs for and wants to entertain. At the very core of her being is a NEW woman who is absolutely in love with the things and ways of God. Her flesh is what doesn't want to love God and needs to be brought into submission to the Spirit.
Maybe.
After a few tries, in the case of a hardened narcissist, you will have to rely on just being Christ-like around them. Confrontation will be counter productive. You have to give 'em up.
Stunned knows all the passages of scripture. What will happen now is these passages will begin to be applied through real life practical situations. For me it was realizing that the fallout from my raging alienated people from me, not brought them near to me in peace as I intended. I knew all the scriptures, what I needed was a real life reason of why they are the truth. She will learn and be convinced with God's help, through her situations, that the scriptures are true and teach the best way for her to handle angry rage. She's already well on her way.
