Jimmy's eagerness to play basketball and his unwillingness to play anything else manifested a grave psychological and character defect. He was an egoist at heart, proud, greedy of honor, of praise and of attention. He craved acclaim. If he was not sure he could get that in a particular activity, he refused to participate in it. The psychology of Jimmy is something that Scripture condemns and warns against in the strongest terms.
Pride is the supreme character fault, according to Scripture.
The term selfishness will be more extensively defined later.
