I remember a student in a high school I was at that constantly reminded me that I had forgotten to give the homework. Needless to say he was not terribly popular. But he was so obsessed with grades that he did not want to take a chance they would get any lower. He was so obsessed that he could not enjoy his success. We can be like that in our life too. James and John were so obsessed they could not see clearly what it meant to follow Jesus.
