It is the normal state of the human heart to try to build its identity around something besides God. Spiritual pride is the illusion that we are competent to run our own lives, achieve our own sense of self-worth and find a purpose big enough to give us meaning in life without God. Søren Kierkegaard says that the normal human ego is built on something besides God. It searches for something that will give it a sense of worth, a sense of specialness and a sense of purpose and builds itself on that. And, of course, as we are often reminded, if you try to put anything in the middle of the place that was originally made of God, it is going to be too small. It is going to rattle around in there.
