Of course there IS evil. Maybe all we can do is try to keep it from overwhelming our individual lives, not give it power. This world can be pretty awful. All we see on the news are the bad things that are happening here. I rarely watch the news anymore. Well, I don't have a television either. I don't miss it. I have enough trouble just managing my own life without obsessing on all the bad things that are happening in other parts of the world, things that I cannot change. In my own small way, I will do whatever I can to not fall under the spell of evil and fear.
The AA and Al-Anon words come to mind here: God grant me the serenity to accept the things I can not change, the courage to change the things I can and the wisdom to know the difference.
Good words to live by but not easy words--by any means.
