We talk of the comfort and joy of Christmas time, but where does that joy come from? How does it begin? Is it based on the pleasant circumstances that surround us at Christmas time? What if a person does not experience pleasant circumstances at this time of the year? Can he or she still have the Joy of Christmas. The answer is “yes”. But in oder to answer the question, we must understand where this joy comes form and what type of joy it is. Isaiah 40 tells us more.
