These people are consumed with themselves. Therefore they expect you to be captivated by them as well. Narcissist try to control your perception of their narcissistic behavior by pretending as if it doesn’t exist.
Love one another with brotherly affection. Outdo one another in showing honor.
( Romans 12:10 )
We must honor all God’s children. Love them flaws and all as Christ loves us. Be firm. If neccessary, sometimes we have to love some people from afar. Even if they are friends or family. This way they can see themselves clearly, but even when they realize it’s no guarantee they will change.
