Pride may be described as a disordered love of self by which a person takes individual credit for what are actually gifts of God and by which a person seeks unreasonable acclaim for personal accomplishments.  Pride springs from an exaggerated egocentrism or self-centeredness.  Of course, there is a self-love that is good and virtuous.  But in pride a person makes "self" absolute and central, isolating self from God and others, or using others for the achievement of selfish purposes.

Boasting, arrogance, vanity, and hard-heartedness flow from the sin of pride and manifests itself in many ways. Here are several.
The Lord of the Manor - this describes people who never learn how to exercise authority.  Whether in the home, the workplace, or the church, these men or women will lord it over others.  Far from caring about the welfare of those subject to them, these "authority figures" dismiss the good of others as they relentlessly seek their own.
The Show-Off - this describes people who act like spoiled children, indulge in vanity and seek self-importance in externals, such as clothes, furniture, or cars.  In their own inflated opinion, whatever they own or use must be better.  Such people often strut around as if they were God's gift to creation.
The Know-It-All - people "wise in their own conceits."  They consider their opinions, once formed, absolutely unchangeable and superior to everyone else's.  Such people are typically full of prejudice against other races, creeds, and groups.  They are generally closed minded and judgmental. 
The Supersensitive Soul - people who hide their pride behind the mask of "hurt feelings."  Those who live or work with such people must "walk on eggs," lest their feelings be bruised.  The supersensitive are constantly seeking apologies from those who have "offended" them. 

Like a roaring lion, pride goes about seeking whom it may devour.  Christians who want to tame this beast will have to stand on guard and use all the tools at their disposal.  One important tool is humility.
