In the Hebrew Scripture several words are translated “pride” which means to exalt (see Job 41:34), to have majesty or excellence (see Isa. 28:1), coupled with arrogance (see Prov. 8:13). In the New Testament there are several words translated “pride” and used only a few times.
“For all that is in the world—the desires of the flesh and the desires of the eyes and pride in possessions – is not from the Father but is from the world” (1 John 2:16). John uses a word which means “empty words,” “empty assurances” or “empty trust.” Everything the person says implies an empty belief and misplaced trust in an object which cannot deliver what is promised.
“He must not be a recent convert, or he may become puffed up (proud) with conceit and fall into the condemnation of the devil” (1 Tim. 3:6). Paul uses a word which means “smoke” or “mist,” having the outward appearance of substance but with nothing inside. Pride blows hot air into a person until they are so big they can see nothing but themselves. Pride is essentially a self-righteous, self-absorbed excuse to view self as not sinful or beyond sin. Pride expresses itself in self-righteousness.
Those who are poor in spirit recognize sin has separated them from the riches of a personal relationship with God. Pride hides truth and inflates self, shutting off every personal relationship. Once one begins working with God there is a continual trial to not place self ahead of Him. It is easy to begin viewing all which has been done, or said, to see the successes and failures, and to attribute them to personal effort. While we live in this world God does not erase the corrupted self inherited through Adam. We must continually fight the tugs and pulls of the world, continually acknowledge sin in ourselves and continually relinquish control. Even John, at the end of his life when he saw Jesus, fell on his face because he recognized his sinfulness.
