You’re almost finished with the beginner mode.  How exciting!  The answer is that the garments of Christ will be stained with the blood of His enemies.  It’s not the prettiest picture, but that is what the Bible says will happen.  Jesus will destroy those who have slaughtered millions of Jews and believers during this time, and He will establish His kingdom on Earth.  Also, the part about burning the foes to ashes is referring to a final battle that happens a millennium later, as recorded in Revelation 20.  For that matter, what chapter in Revelation shows Jesus coming down on a white horse to vanquish His enemies?

-Revelation 6-

-Revelation 12-

-Revelation 19-
