The fiery-colored horse, whose rider has authority “to take peace away from the earth.” (Revelation 6:4) Since 1914, war has constantly plagued mankind. Just 21 years after World War I ended, a second world war broke out, killing far more people. One estimate says that World War II cost some 60 million lives. Since 1945, wars have been more localized but just as brutal. Some historians estimate that well over a hundred million people lost their lives in wars during the 20th century.
