Confidence is not the same as "self-esteem" and yet most people think of confidence when they hear the words "self-esteem."
"Self-esteem" is esteeming ourselves better than others.
Philippians 2:3-5
In other words, the "self-esteem" doctrine is against God's word and according to faulty human wisdom.
Confidence resides in a person who knows what they believe and trust in Christ for His wisdom. Confidence does not cause us to treat others as beneath us, but it does allow us to carry on our lives without fear of what others think of us.
Confidence allows us to be kind to those who are unkind to us. It allows us to defer to others because of our love for Christ and for them.
Those who are confident do not think of themselves very much, they just live the way they believe and share truth with others to help them.
Those who narcissistically live by self-esteem are those who lack confidence needing to be superior in order to feel good about themselves. Their own interests and their own feelings take priority over everyone else. These people cannot learn, they remain emotional and spiritual infants always on the defensive to prove themselves to others. They can never receive a correction and are always correcting and judging others.
A confident person need not feel superior to anyone and can boldly state their beliefs because they do not fear the reactions or retaliation of others.
Confident people walk in love and truth as a lifestyle.
1 Corinthians 13:4-8a "Love is patient, love is kind. It does not envy, it does not boast, it is not proud. 5 It does not dishonor others, it is not self-seeking, it is not easily angered, it keeps no record of wrongs. 6 Love does not delight in evil but rejoices with the truth. 7 It always protects, always trusts, always hopes, always perseveres.
8 Love never fails."
Love does not show partiality or need to impress those they think are superior to others.
A confident person feels no need to explain to others why they do things although they may have dialogues to clear up misunderstandings with those who are rational and reasonable. Those who would invite a good discussion to resolve things will want to discuss matters in love, this is what makes good relationships.
Our world is rampant now with those who are madly in love with themselves and enraged when someone challenges them to self-reflect for emotional and spiritual growth.
We cannot help those who refuse to be helped and we cannot have a relationship with those who want only to be superior to us. These people judge only two ways, they see those they admire as perfect and those they don't admire as all bad. They are not able to see someone in truth and love them, warts and all. Narcissists live vicariously through those they elevate while denying the good in those who are judged as imperfect.
In other words, the love of a narcissist is not love at all but conditional to our performance that matches pitch with the elevated idea they have of themselves.
What a blessing it is when we meet people who are honest open and loving, ready to discuss things as we all grow and learn from one another. There is no pretense with God's people, just authentic love as they live out their life in Christ.
It is also a blessing to enjoy the company of others we know are imperfect because we know we all are lacking in something. The beauty of the loving Christ like relationship is that we accept and love a person with all their blessings and warts. There is no pride or self-promotion involved in genuinely righteous brothers and sisters in Christ.
God told us to walk away from those who say they are Christians but who walk disobediently through self-exaltation. We can pray for them and even rebuke them at times but they cannot be our constant companions, they will bring out the worst in us and we will enable their bad behavior by remaining with them.
Galatians 5:22-23
"But the fruit of the Spirit is love, joy, peace, patience, kindness, goodness, faithfulness, / gentleness, and self-control. Against such things there is no law."
Ephesians 4:2
"with all humility and gentleness, with patience, bearing with one another in love,"
Colossians 3:12-14
"Therefore, as the elect of God, holy and beloved, clothe yourselves with hearts of compassion, kindness, humility, gentleness, and patience. / Bear with one another and forgive any complaint you may have against someone else. Forgive as the Lord forgave you. / And over all these virtues put on love, which is the bond of perfect unity."
1 Peter 4:8
"Above all, love one another deeply, because love covers over a multitude of sins."
God made it clear that we are to edify one another, that is help one another to walk more Christlike with great compassion toward one another.
