Pride (Latin superbia) is considered in almost every list to be the original and most serious of the seven deadly sins. Of the seven, he is the most demonic. It is also believed to be the source of other deadly sins. Pride is known as arrogance (from the Greek. ὕßρις) or futility, as depraved egoism, as putting one's own desires, motives and whims above the well-being of other people.

Since pride was called the father of all sins, it was considered the most prominent feature of the devil. K. S. Lewis writes in "Just Christianity" that pride is a state of "anti—god", a position in which the ego and personality are directly opposite to God: "Unchastity, anger, greed, drunkenness and all that — in compared with pride, this is nothing: it was through pride that the devil turned into the devil: pride leads to all other vices: this is a completely anti-divine state of mind. It is believed that pride separates the spirit from God, as well as from His life-giving and gracious presence.

You can be proud for various reasons. Author Ichabod Spencer states that "spiritual pride is the worst kind of pride, if not the worst trap of the devil. The heart is especially crafty in this regard. Jonathan Edwards said: "Remember that pride is the worst snake in the heart, the greatest violator of the peace of the soul and sweet communion with Christ; this was the first sin that ever existed, and it lies at the heart of the whole building of Satan and is the most difficult to eradicate, and is the most hidden, secret and deceitful of all lusts, and often invisibly penetrates into the thick of religion, sometimes under the guise of humility.
