As a very occasional 'stand-up' I maintain that comedy is an art form, so it fits with the general idea of our Advent blogs containing various arts. Humour is also, I believe, a source of strength, resilience, and hope - when we are able to laugh in the midst of difficult times, when we can laugh at those things which also cause us anxiety, when we can laugh at ourselves, we make ourselves stronger, and remind ourselves that laughter and love are stronger than fear and despair.
A cheerful heart is a good medicine,
but a downcast spirit dries up the bones. Proverbs 17.22
