We want to believe the world is understandable. That life is fair, That things make sense. We want to believe that if we're careful enough, work hard enough, try hard enough, we and those we love will be safe from anything bad.
It's one of the biggest questions human wrestle with - why things sometimes aren't fair. But even though we don't always have a neat answer to why things happen, we do have each other... and we have our faith.
Just a simple kind of faith that somehow, someday, suffering will end, good will be rewarded, love will endure, pain will be forgotten, light will scatter darkness, and our spirits will go on.
