I thought it was kinda funny (just kinda) that there is actually a legitimate medical condition for selfishness. Its called Narcissistic Personality Disorder or NPD. Heres the test...
Symptoms & Signs
need constant attention and admiration
exaggerate achievements and talents
react to criticism with feelings of rage, shame, or humiliation
be impulsive, anxious, or envious of others
take advantage of others to achieve his or her own goals
expect special treatment
be preoccupied with ideas of unlimited success, power, brilliance, strength, and beauty
become quickly dissatisfied with others
The devil is a narcissist and so are all of us when we fail to allow the Spirit of Christ to rule within us.This website claims that there are no cures or prevention for NPD . Of course we Christians know better.
Phil 2:3Do nothing out of selfish ambition or vain conceit, but in humility consider others better than yourselves. 4Each of you should look not only to your own interests, but also to the interests of others.
