I just read an interesting take on that over at Jesus Creed by Mike Glenn; he blogs there every Friday. Here's a snippet, but please read the whole thing and think about it:
Here’s what I do know. Violence starts somewhere. Violence doesn’t just blow into our lives from parts unknown. There’s always a trail. There’s always a beginning point, a poke, that starts the violence. While we may not be responsible for any particular act of violence, all of us are responsible for creating an atmosphere, a world view where violence is an acceptable course of action.<idle musing>
We watch movies where the hero has finally had enough and kills his enemy in the most violent way possible. The bigger the bang, the better the movie. We play games where the object of the game is to become the most violent person in the game. Kill our adversaries with such efficiency we’re given more points to obtain more weapons to be more violently efficient in our killing. This is fun?
Here’s where we need to pay attention to the genius of Jesus’ teaching. Remember when Jesus taught us that if we were angry with our brother we were guilty of murder? That if we harbored lust in our minds for a woman, we were already guilty of adultery?
The early Christians were known for their radical love and care for those around them—even those who persecuted them. May we emulate them!
