Pride is a very misunderstood sin, and many are sinning in ignorance. Therefore, no matter how the world uses the term, we must understand how God uses the term so we can understand the language of holy writ and profit thereby. Most of us think of pride as self-centeredness, conceit, boastfulness, arrogance, or haughtiness. All of these are elements of the sin, but the heart, or core, is still missing. It is the power by which Satan wishes to reign over us.
Pride is essentially competitive in nature.
We pit our will against God's. Our will in competition to God's will allows desires, appetites, and passions to go unbridled. The proud cannot accept the authority of God giving direction to their lives. They pit their perceptions of truth against God's great knowledge, their abilities versus God's priesthood power, their accomplishments against His mighty works. The proud wish God would agree with them.
