4 Bible Verses about Overestimation

For by the grace [of God] given to me I say to everyone of you not to think more highly of himself [and of his importance and ability] than he ought to think; but to think so as to have sound judgment, as God has apportioned to each a degree of faith [and a purpose designed for service].

For if anyone thinks he is something [special] when [in fact] he is nothing [special except in his own eyes], he deceives himself.

Live in harmony with one another; do not be haughty [conceited, self-important, exclusive], but associate with humble people [those with a realistic self-view]. Do not overestimate yourself.

If I wish to boast, I will not be foolish, because I will be speaking the truth. But I abstain [from it], so that no one will credit me with more than [is justified by what] he sees in me or hears from me.
