Narcissists do more lying by omission and actions than by words. They twist the truth to come out the opposite of what actually happened by their personal spin on everything. They say one thing and do the opposite often.
Since they act superior they must spin everything to their own advantage. If we have said something profound they will negate it and come back two days later saying the same thing as though it was their own idea in the first place.
I have seen this many times! They will even use exactly the words to others that you said as though they were the ones who originated it. They will never give credit to anyone else for a good idea or a good job.
They will even tell you what a bad idea you had and then go off and do the idea as though you never had it, that it belonged to them. If we were to call them out on it they would make us look childish and silly for suggesting that the idea did not originate with them. Narcissists are like devils, they are counterfeiters to elevate self above all others.
When a narcissist says "I am one of the friendliest people you will meet." It just shows us that they have a high opinion of themselves that does not match at all with what others are seeing. They must try to convince others of things about themselves with words that they know are not true in reality.
I know the reason, if they acknowledge you are the good person they are speaking about then they have to feel like nothing at all.
Sadly if they cannot be everything better than others then they are nothing at all, in their own minds. They are pridefully wishing to be superior but in reality, they are deeply insecure or they would not need to make up lies about themselves. It is easier to "say" things than to actually "be" those things.
People who are confident do not have to boast about themselves, they are just happy being what they are and doing what they do without impressing anyone.
This is also why confident people can easily admit flaws because the flaws are not all they are, only a part of them that needs some work. That's why confident people grow and change for the better over the years, they are fixing things as needed.
Narcissists cannot admit the truth about their flaws, the very reason they do not grow emotionally or spiritually beyond the mentality of a bratty six-year-old.
Narcissists lie to themselves constantly, which is why they cannot tell the truth to anyone else. Their father is the father of lies. The devils influence their thinking to make them feel superior just as Satan did in the garden with Eve. He convinced her she could be her own god. The narcissists would melt into a puddle on the floor if they ever had to admit a flaw, the very attitude that keeps them in a state of infancy.
Proverbs 14:2-3 "…2 He who walks in uprightness fears the LORD, but the one who is devious in his ways despises Him. 3 The proud speech of a fool brings a rod to his back, but the lips of the wise protect them."
It is clear that a narcissist is a fool, one who will continue in foolishness even when that foolishness loses him something. He would rather hang onto his pride and diluted superiority than admit wrong and grow emotionally and spiritually.
Proverbs 18:5-6 "…5 Showing partiality to the wicked is not good, nor is depriving the innocent of justice. 6 A fool’s lips bring him strife, and his mouth invites a beating. 7A fool’s mouth is his ruin, and his lips are a snare to his soul.…"
Our culture in this day of apostasy has trained the youth to defend their pride to praise themselves causing them to maintain infantile thinking well into their middle age.
I could be wrong but I am convinced that someone who remains infantile into their middle age will likely never come out of it. There is only one hope for them and that is to admit their sinfulness, repent and trust in Christ. Without this, there can be no change and no salvation. Change only comes after trusting in Christ, sadly, trusting in Christ is unlikely for those who are so deeply narcissistic that they will never admit they are sinful, although I have heard of some who have repented and come to Christ.
If we know a narcissist we can keep praying until God tells us to stop. If someone is a narcissist they have only two choices, admit their sin and trust Christ or remain as they are and go to hell.
No one can be a full-blown narcissist after trusting in Christ. Christ changes our character into a completely different person after the born-again experience. If someone remains a narcissist and claims to be a Christian they are lying and were never born again. These are sobering thoughts in a modern Christian world in which words seem to be enough to convince someone we are a Christian.
Here is the evidence that someone has become born again.
Galatians 5:22-23
"22 But the fruit of the Spirit is love, joy, peace, patience, kindness, goodness, faithfulness, 23 gentleness, self-control; against such things there is no law."
The fruit of the Spirit is the character qualities of Christ, no one is born again who lacks this fruit, all of the qualities must be present.
