Why "the peace of God, it is no peace..."

Wendell Berry:

Here is the other question that I have been leading toward, one that the predicament of modern warfare forces upon us: How many deaths of other people’s children by bombing or starvation are we willing to accept in order that we may be free, affluent, and (supposedly) at peace? To that question I answer: None. Please, no children. Don’t kill any children for my benefit.

If that is your answer too, then you must know that we have not come to rest, far from it. For surely we must feel ourselves swarmed about with more questions that are urgent, personal, and intimidating. But perhaps also we feel ourselves beginning to be free, facing at last in our own selves the greatest challenge ever laid before us, the most comprehensive vision of human progress, the best advice, and the least obeyed:

“Love your enemies, bless them that curse you, do good to them that hate you, and pray for them which despitefully use you and persecute you; That ye may be the children of your Father which is in heaven: for he maketh his sun to rise on the evil and the good, and sendeth rain on the just and on the unjust.”
