4 Bible Verses about Overestimation

For I say, through the grace that unto me is given, to every man among you: that no man esteem of himself more than it becometh him to esteem - But that he discreetly judge of himself according as God hath dealt to every man the measure of faith.

If any man seem to himself that he is somewhat, when indeed he is nothing, the same deceiveth himself in his imagination.

Be of like affection one towards another. Be not high minded, but make yourselves equal to them of the lower sort. Be not wise in your own opinions.

and yet though I would rejoice I should not be a fool, for I would say the truth. Nevertheless I spare, lest any man should think of me above that he seeth me to be, or heareth of me.
