Hold on to that thought.
I've also heard a lot of stuff about pride. The general definition I've heard is: Pride is focusing on yourself. Basically, making you the center of your life.
Now, back to what I said earlier. Who is the main subject in "putting yourself below others"? Others, like it should be? Nope. It's you. That statement is about you. So really, you are focusing on yourself. Which is pride. One term for putting yourself below others (I think) is self-deprecation, or at least thats how i use it. And what I've found is that self-deprecation is no more than a twisted form of pride. Humility is putting others above yourself, not yourself below others. Talking yourself down is not the same thing as lifting others up. There is huge difference here, because the humility Jesus calls us to have is focusing on others; putting others above yourself. Putting yourself below others is trying to put a mask on pride; it's still there, but it's hidden where its much harder to see, and therefore it grows in a much more dangerous way. It festers behind a mask of "humility".
(This was on my iPod, so it's shorter than it might otherwise be and there are probably some grammar/wording issues).
