Proverbs 22-25 "24 Do not make friends with an angry man, and do not associate with a hot-tempered man, 25 or you may learn his ways and entangle yourself in a snare.…"
The reason it is not wise to be constant companions with narcissists is because their tactics are designed by the devil to poke at us until we respond the way they act, in anger.
We are wise when we ignore an insult and remove from our lives those who act disrespectfully on a regular basis.
A person with the fruit of the Spirit, love, joy, peace, gentleness, kindness and self-control, we never treat others with disdain. Our character will be what comes out of us continually. If a person is angry they will act mean on a regular basis. The angry narcissists will be rude to those they wish to hate and friendly to those they wish to impress. They are fake when they are kind and lie to themselves that those they treat disrespectfully deserve it.
If a person is loving and kind they will act this way continually with everyone. Those who are filled with the Spirit of God hate to harm anyone even in the slightest way. If they are accidentally rude, perhaps bumping into someone in the super market aisle they will apologize. A narcissist will blame the person they bump into for being in their way.
The fruit of the Spirit of God operates in this fruit all the time with everyone, they do not favor one person over another. Their love and kindness does not come and go, it is constant.
Galatians 5:22-23 - "But the fruit of the Spirit is love, joy, peace, patience, kindness, goodness, faithfulness, gentleness, self-control; against such things there is no law."
The fruit of the Spirit is not something we can try to be, it is given when someone becomes, given by Christ when we become born again. The fruit are the qualities of Christ that dwells in every believer.
If you meet someone who plays favorites and is mean to some people and overtly friendly to others, and justifies it, then you have met someone who says they are Christian but were never born again. They are playing the game of Christian without possessing the Holy Spirit. Many people in our culture today fit into this category.
Matthew 7:21-23
I Never Knew You
21 “Not everyone who says to me, ‘Lord, Lord,’ will enter the kingdom of heaven, but the one who does the will of my Father who is in heaven.
22 On that day many will say to me, ‘Lord, Lord, did we not prophesy in your name, and cast out demons in your name, and do many mighty works in your name?’
23 And then will I declare to them, ‘I never knew you; depart from me, you workers of lawlessness.’"
When we discover that someone is a pretender it is good to keep our distance from them. They will become easily angered at the slightest suggestion that they need an attitude adjustment through confession of their sinful nature and to be changed by the Holy Spirit. They need the salvation message once again.
When someone refuses to hear a correction and fights to exact revenge on the truth teller then they are not able to hear the truth and we must avoid them.
2 Timothy 3 describes the attitudes in the church in the last days of apostasy. They pretend to have "religion" but they do not love Christ.
2 Timothy 3:1-5 "3 But understand this, that in the last days there will come times of difficulty. 2 For people will be lovers of self, lovers of money, proud, arrogant, abusive, disobedient to their parents, ungrateful, unholy, 3 heartless, unappeasable, slanderous, without self-control, brutal, not loving good, 4 treacherous, reckless, swollen with conceit, lovers of pleasure rather than lovers of God, 5 having the appearance of godliness, but denying its power. Avoid such people."
