A few months ago I offered the following remarks in a blog post, in answer to what Christians should think of Wayne LaPierre's idea that a good guy with a gun is the only thing that can stop a bad guy with one:
If there’s a common theme in Jesus’ ministry and message, it’s about a different way of responding to evil, to injustice, to violence, than the traditional human response of fighting fire with fire. Jesus’ life and death were a testament to this divine Third Way—a way that refuses to identify sin with sinners, evil with evil-doers, that insists on the possibility of redemption and seeks to transform a violent situation not by a final lethal stroke of violence, but by a creative act of love—even, if necessary, love that suffers unto death.
As a response to evil, there’s an unbridgeable gulf between picking up a cross and picking up a gun.
