I was once told of a young woman who spent many hours screaming at construction workers starting a job with which she disagreed. Afterwards she went in to nurse her baby and the child died. It was the conviction of the person who told me the story that the woman's anger and hatred had somehow produced something toxic in her body, which affected her baby. I don't know if that's possible, but I have seen hatred poison lives in other ways, and poison society as well.
Apathy isn't the answer. Empathy, action, service and love point us in new directions with possible solutions.
Paul wrote to the Philippians that if there is anything true, honorable, just, pure, pleasing, commendable...if there is any excellence and anything worthy of praise, we should think about these things. (Philippians 4:8) Perhaps in other words it could be said that if we're going to give anything rental space in our brains and our hearts - it ought to be something worthy of spending time there. If we spend enough time with such valuable companions, our lives will reflect it also.
