So much of our sense of decor and festivity surrounding the Christmas season has its roots in the Victorian era. At that time, Christmas became "packaged". The package is a nostalgic vision of a warm home, full of life and good cheer. This package was developed during a time of cold and harshness outside, and that became the essence of the Victorian Christmas: the contrast between a harsh, cold, backbreaking life outside with a warm, loving, and content inside.
This is a wonderful theme of Christmas ... well ... assuming that both sides are emphasized. And much too frequently we might emphasize the warmth and nostalgia without first approaching Christmas from out of the cold, harshness of the world.
Indeed, the foundation of Christmas is humility - thinking not of ourselves and looking for something greater than ourselves, which ultimately brings us to a place of contentment. But, it will forever be difficult to experience the genuine warmth of Christmas without also experiencing the humility of Christ.
