In the Revelation in the Bible, the Dragon comes back up from the abyss after "1000 years" (meaning a long time). What people don't realize is that there are two basic reasons why Satan (the dragon) comes up from the abyss (his death): 1) To go into his destruction in the lake of fire (which is the destruction of this universe); 2) because the people are asking for him to come up, even though many of them don't realize what they are doing.
