An interesting definition of pride as put forth by Pres. Ezra Taft Benson. I found it in the chruch's Addiction Recovery Manual. Remember this one the next time you talk about it in Sunday School. Then you won't have the same old lame conversation about "good" pride and "bad" pride. If you get everyone on the same page with respect to the definition you can have a good conversation about it.
“Pride is a very misunderstood sin. . . .
“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.
“The central feature of pride is enmity—enmity toward God and enmity toward our fellowmen. Enmity means ‘hatred toward, hostility to, or a state of opposition.’ 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. When we direct our pride toward God, it is in the spirit of ‘my will and not thine be done.’ . . .
“Our will in competition to God’s will allows desires, appetites, and passions to go unbridled (see Alma 38:12; 3 Nephi 12:30).
“The proud cannot accept the authority of God giving direction to their lives (see Helaman 12:6). They pit their perceptions of truth against God’s great knowledge, their abilities versus God’s priesthood power, their accomplishments against His mighty works” (in Conference Report, Apr. 1989, 3–4; or Ensign, May 1989, 4).
