I remember reading about the seven deadly sins in the Faerie Queen in high school. Pride is such a key to all of them, a love for self that has permutations in various pleasures or behaviors. Pride gives way to each of them. But pride in and of itself is destructive on its own.
We see it in the faces of small children who don't receive a trophy or win a game. They are hurt not because they scored fewer times, but because they did not receive glory. It is easy to see in them, they haven't yet become skilled in covering up their pride and self-seeking attitude.
But we adults are the same way. We dislike being neglected, forgotten, behind the scenes, because we want attention, honor, glory. Maybe we don't want it in all areas, but each of us has an area we really care about, something we want recognition for, or something we feel we deserve.
Whether we deserve it or not, whether it is given or not, I have found it imperative to be willing to bring myself to my knees and kill those desires. Unless a seed die... Unless I die to myself, I am rejecting the life of joy where God's glory is made manifest. How much better to live in awe and wonder at what God is doing, rather than be puffed up with myself.
