We talk glibly of the ‘Christmas spirit’, rarely meaning more by this than sentimental jollity on a family basis….the phrase should in fact carry a tremendous weight of meaning. It ought to mean the reproducing in human lives of the temper of Him who for our sakes became poor at the first Christmas. And the Christmas spirit itself ought to be the mark of every Christian all the year around….
The Christmas spirit does not shine out in the Christian snob. For the Christmas spirit is the spirit of those who, like their Master, live their whole lives on the principle of making themselves poor–spending and being spent–to enrich their fellowmen, giving time, trouble, care and concern, to do good to others–and not just their own friends–in whatever way there seems need.
