I recently watched this video were John Piper explains the specific form of pride in his life:
My default sinful emotion starts with a sense of frustration that it didn’t go my way and I didn’t get what I wanted; at home, at church, or here at Desiring God. And then I begin to sink into, “Oh poor me,” and can justify it in all kinds of ways. So I just retreat, go inside, and sulk.
I couldn’t have written a better description of my own sin if I tried.
