Everywhere, the Bible shows the same principle: Pride has its roots in a feeling of wealth or accomplishment, which is then used to compare. We can tie this to Satan and what is written about him in Ezekiel 28, how pride arose within him because of his beauty. He had something to brag about that made him feel good. But his vanity, developing into outright pride, began to get to him. He began to feel better than the other angels, and eventually, in his own eyes, he equated himself with God. In time, he thought of himself as greater than God—a very perverted comparison.
It does not have to be intelligence or beauty or power as it was with Satan. It could be things like money, position, social position, natural ability, social status, knowledge, strength, hair, clothing, a house, furniture, automobile—the list is virtually endless. In the New Testament, the Greek is huperephania, which means "to show oneself above." It does not imply one who others look up to, but one who stands on his own self-created pedestal.
Psychologists tell us that pride is actually a mark of inner inferiority and uncertainty, and such people compensate by over-emphasizing and flaunting the qualities that they think they possess that will make others think well of them. This feeling of wealth is highly relative because each person is capable of setting his own standards of comparison, regardless of his real accomplishments.
Proverbs 26:16 speaks of the sluggard who is wiser in his own eyes than all others, who can render more answers than seven wise men can. Although he is virtually devoid of anything that anybody would consider worth bragging about, the sluggard has created his own set of standards. He thinks he already knows the answers. He has a feeling of wealth, of prosperity, of power, or of security in whatever standard he in his own conceptions has set. He is so sure that he knows the answers that he is undeterred by facts and continues then in his ignorance. He is self-sufficient.
