I found these words to be very powerful. They were spoken in 1984 by Ron Sider, a man who has done much to transform the world. He is speaking at the Mennonite World Conference when he says,

Unless we are prepared to risk injury and death in nonviolent opposition to the injustice our societies foster, we don’t dare even whisper another word about pacifism to our sisters and brothers in those desperate lands. Unless we are ready to die developing new nonviolent attempts to reduce international conflict, we should confess that we never really meant the cross was an alternative to the sword. Unless the majority of our people in nuclear nations are ready as congregations to risk social disapproval and governmental harassment in a clear call to live without nuclear weapons, we should sadly acknowledge that we have betrayed our peacemaking heritage. Making peace is as costly as waging war. Unless we are prepared to pay the cost of peacemaking, we have no right to claim the label or preach the message.
