Depression and suicides spike at Christmas, as loneliness and the memories of lost loved ones invade the background cheer. My own father died in mid-December, before his twenty-fourth birthday, an untimely death that forever cast a pall over our family's Christmases. We know, all of us, the dissonance of which Simeon spoke to Mary: of love splattered with blood, of consolation that proves diffused and fleeting. Art brings that dissonance to the foreground, with a poignancy that wounds the spirit like a sword.
--Philip Yancey, from the foreword
