Step 7 is a step where (as with the other steps) action is taken, but the emphasis is on how the action is taken. We don’t roll up our sleeves and begin ridding ourselves of our defects of character. We don’t make a demanding request of God to take them away. We humbly ask.
Humility is often thought of in simple distinction from arrogance. This binary distinction would imply that arrogant people think very highly of themselves and humble people think very lowly of themselves.
A synthesis of passages from Scripture (rather than only single passages treated as knock-down proof-texts!) would seem to suggest that a Christian understanding of humility is to think of one’s self wisely. Neither too highly or too lowly.
In my own experience, and the experience I hear from others, thinking too highly of ourselves is very common, and possibly why it seems to get the most corrective in Scripture. But I suspect that very often, if not almost always, the act of thinking highly of ourselves, or making ourselves out to be something great, is an act of compensation. It is to counter beliefs or feelings that we are worth nothing or very little. We feel low, so we perform, exaggerate, brag or draw attention to ourselves to compensate.
If this is true, then at least some of the time, the answer to narcissism is proper self-confidence.
