A look at Christmas and how people spend money in the United States and in the U.K.; a fascinating look at the Caesar found in the gospels; the coolest story of a bridge you will ever hear (the Choluteca in Honduras); Darwin on 'purposelessness';  the cost of taking little and big exits in marriage and in faith; the most practical lesson ever on Michelangelo's "Creation of Adam" and why it defines our spiritual lives; the power of knowing Emmanuel; and the story behind the hit song "Mary Did You Know".
