Finding hope in adversity is one of the themes of Christmas. Jesus was born into a world full of fear. The angels came to frightened shepherds with hope in their voices: 'Fear not', they urged, 'we bring you tidings of great joy, which shall be to all people.God save the Queen.
'For unto you is born this day in the City of David a Saviour who is Christ the Lord.'
