With how much violence they will pass away is up to us. Insofar as we are willing to let them go there will be less violence - insofar as we have been able to build the new within the old there will be less violence, so let us work on that. In order to help usher in the golden age we must see the good in the people - we must know it is there, no matter how deeply it may be buried. Yes, apathy is there and selfishness is there - but good is there also. It is not through judgement that the good can be reached, but through love and faith.
Love can save the world from nuclear destruction.
Love God - turn to Him with receptiveness and responsiveness. Love your fellow human beings - turn to them with friendliness and givingness. What people really suffer from is immaturity. Among mature people war would not be a problem - it would be impossible. However, people can mature just as children can grow up.
