Reporters and city officials gathered at a Chicago railway station one afternoon in 1953. The person they were meeting was the 1952 Nobel Peace Prize winner. A few minutes later the train came to at stop and a giant of a man - six feet four, with bushy hair and a large moustache - stepped from the train. Cameras flashed, city officials approached him with hands out-stretched, various ones began telling him how honoured they were to meet him.

The man politely thanked them and then, looking over their heads, asked if they would excuse him. He walked through the crowd and reached the side of an elderly black lady struggling with two large suitcases. He picked up the cases and with a smile escorted her to a bus. After helping her on board, he wished her a safe journey. Returning to the greeting party, he apologised for keeping them waiting.

The man was Dr Albert Schweitzer, the famous missionary doctor who had spent his life helping the poor in Africa. In response to Schweitzer's action, one member of the reception committee said with great admiration, "that is the first time I ever saw a sermon walking."

Let us pray that people will see us as walking sermons.
