A small boy forgot his lines in the Sunday school presentation. His mother sat in the front row and tried to prompt him by gesturing and silently forming words with her lips. It was no use. The boy's memory went blank.
Finally she leaned forward and whispered his cue: "I am the light of the world."
With broad smile and beaming confidence, the child sad in a loud, clear voice: "My mother is the light of the world."
