Who Would Jesus Bomb?

I saw this title on a bumper sticker, and then I read the following excerpt from Seeking God's Peace in a Nuclear Age: A Call to Disciples of Christ:

At the heart of our new vision and new venture on the course toward peace will be Jesus the Christ. His way of love is infinitely more powerful than the way of war and violence. "Returning violence for violence multiplies violence, adding deeper darkness to a night already devoid of stars. Darkness cannot drive out darkness; only light can do that. Hate cannot drive out hate; only love can do that." Yet humankind still clings to the ancient fallacy which claims that we can use force to rearrange the external political configurations and thus the wrongs of the world will be set right. Instead of tinkering with these surface externals, Jesus the Christ attacks evil in its breeding place--the heart of humanity: the hearts of nations, the hearts of institutions, the hearts of persons. Here is supremely the place where the church must focus its vision. Weapons of war are set to their task by the human hand, but the hand is set to its task by the human heart. Thousands of years of human experience have proved over and over again that the heart of all transformation is the transformation of the heart.

I found the excerpt in A Guide to Prayer for All God's People.
