I find I am most arrogant when I feel worthless or insignificant. And when I am feeling confident, affirmed and supported I feel I can risk humility. This seems to fit the “opposite rule.” That is, the arrogant are really insecure. The tough guy or girl fears they are weak. The boastful believes he or she is nothing of value.
When I am arrogant, tough, or boastful, please give me grace. Remember that what I need from you is love, affirmation and sense of worth and value. They may be the last things I deserve and the last things you “feel” like giving.
But watch God make them work.
