One of the biggest difficulties in our contemporary society is that we try to locate the evil in somebody else and then we try to get rid of him. The police are pigs or the students are worthless, and so on and so on. The Marxists are the devils or the Republicans are the devils or you name it. We try to isolate the evil and then get rid of it. But the teaching of the Bible is that we are thoroughly entrenched in this ourselves, so we can't toss rocks at someone else; we have to see the extent to which the moral ambiguities fall directly on us. We need forgiveness; and only when we receive it do we have our lives cleaned up so that we can start seeing situations accurately.
