Flannery O'Connor, the insightful Roman Catholic writer, lifted up the Christian dimension when she wrote: "You will have found Christ when you are concerned with other people's sufferings and not your own." The beginning of compassion involves becoming aware of the suffering of others. 

But it is not enough simply to see the suffering of others, we need to feel it. It is possible to see suffering, but not to feel it. Dewitt Jones tells about a photographer who walked down the street one day and came upon a man who was choking. "What a picture," he thought. "This says it all: A man, alone, in need. What a message!" He fumbled for his camera and light meter until the poor fellow who was choking realized that help was not forthcoming. He grabbed the photographer's arm and gasped, "I'm turning blue!"

"That's all right," said the photographer, patting the fellow's hand, "I'm shooting color film." Just noticing suffering isn't enough.
