Rom 12:16c . . Don't be wise in your own conceit.
Webster's defines "conceit" as excessive self-appreciation of one's own worth or virtue. In other words we're talking about hubris; which often indicates a loss of contact with reality and an overestimation of one's own competence, accomplishments or capabilities.
Conceit is uncivil, untrainable, and intolerable. It truly believes nobody beneath its dignity could possibly have anything to tell that it doesn't already know; and if it doesn't already know, then that's because the information possessed by those beneath its dignity isn't worth knowing.
Those kinds of people will interrupt you right in the middle of your sentence and begin talking about their own perspective as if your voice is nowhere to be heard in the whole room. You know why they do that? Because they sincerely believe that nothing you are in the midst of saying is nearly as important as what they have to say. In other words: you, and your thoughts, are superfluous.
Conceited folk are generally very picky about their influences too; in other words, even if somebody is a Spirit-gifted Bible teacher, but are neither published, accredited, or properly educated, then forget it. That Spirit-gifted somebody is eo ipso undeserving of conceit's intellectual attention right out of the box.
Conceit is not only stuck on itself; but very critical of others too. I've seen it to happen time and again that when a Spirit-gifted Bible teacher comes across with a personality like Elijah's or John the Baptist's that conceit summarily brushes them off as "unloving" no matter even if they speak as the very voice of God. In other words; conceit disdains to be taught; rather, conceit seeks to be accommodated.
I think most people in church are aware that conceit is unacceptable.
● Matt 5:3 . . Blessed are the poor in spirit, for theirs is the kingdom of heaven.
Conceit is a psychological disorder, so people can't just turn it off at will. But unless something radical is done to correct their conceit; people will have to face the sum of all fears.
● Matt 18:3 . .Truly I say to you, unless you are converted and become like children, you shall not enter the kingdom of heaven.
