When a narcissist is accusing you of doing something kind to manipulate them, they are telling you something important. They are telling you that when they do a kind act they are manipulating.
Narcissists make it a practice of blaming others for their own bad behavior. When we encounter this it is best to ignore them without response or if we are led by the Holy Spirit we can state without reservation; "you are speaking about yourself" and leave it there.
They may come back for another pass later but will not remain when their target continues in steadfastness and confidence without emotion.
Our emotions can be the death of us if we use them to evaluate life's experiences. Emotions are the shallowest part of our being and are based on stimuli, they have little substance and should never be relied on to direct our path.
God allows us the wisdom to ignore our emotions to carry on to do His Will. We never deny our emotions, they help us see what still needs work in us. However, we must never allow emotions to be the guiding force behind our decisions.
Our emotions ought to cause us to self-reflect evaluating our own hearts, they can be useful for that, but they cannot be trusted in determining our steps.
Notice in these end times forgiveness without confession and determining emotions as the guiding force behind what we do has destroyed our culture.
"Trust your gut" is the new religion. As born-again believers, we can trust what Christ in us tells us but it is not wise to trust our "feelings or emotional sense" about anything.
We need to be developing godly discernment based on the Bible, not our emotions or anyone else's reactions to us.
Hebrews 5:14
"But solid food is for the mature, for those who have their powers of discernment trained by constant practice to distinguish good from evil."
Philippians 1:9-10
"And it is my prayer that your love may abound more and more, with knowledge and all discernment, so that you may approve what is excellent, and so be pure and blameless for the day of Christ,"
Our wisdom must come from the Bible and not the prevailing cultural standard based on psychology and Darwinism. These worldly systems say the opposite of what God says and create chaos and misery in the world. God's discernment creates peace and love, as I said; the opposite of God's ways.
It's either God's way of peace or it is the world's way of misery and destruction.
