There were more Christian martyrs in the twentieth century than in all of the previous nineteen centuries combined. Hitler, Stalin, Mao, Pol Pot, and many of their lesser-known totalitarian colleagues put millions of Christians to death for their faith in that terrible hundred- year period. One of the saddest features of the still-young twenty-first century is that this awful trend is undoubtedly continuing. By far the most persecuted religious group in the world today are Christians, and they are dying by the thousands especially in the Middle East and in Africa.
