Is Jesus only the consoler and the helper of the individual in a world that forces people to do evil? Does he, against the background of personal forgiveness of sin, merely sanctify an ethics based on this old world, letting the old world ultimately be as it is? Or does the totality of human life rather meet the totality of divine conditions for life in Jesus? … Is Jesus indeed such a totally new world that fundamentally all our ethics, still built on the basis of the old world, is destroyed in encounter with him?
