And DEATH and HADES were THROWN INTO THE LAKE OF FIRE.
The personification of DEATH and HADES makes us think about what really happened here. The obvious view is that DEATH is the physical death of these non-believers, and HADES is the departed souls of these non-believers. These non-believers are the ones who missed the FIRST RESURRECTION (Revelation 20:6). But there is a broader meaning. Just as we have discussed previously, evil is being totally expunged from the earth, and the earth will be totally redeemed by the Jesus Christ who is revealed in this Bible book. It is fitting that anything that has come into contact with EVIL also must be purged. And, thus, both DEATH (which is the wages of sin - ) and HADES are consigned to THE LAKE OF FIRE.
DEATH and HADES didn't go willingly; they were THROWN into THE LAKE OF FIRE. Not much is said in scripture about THE LAKE OF FIRE. It, obviously, is an eternal spiritual container controlled by God. God is a black-and-white God. He doesn't tolerate any gray areas. So EVIL must be compartmentalized for eternity in the LAKE OF FIRE (Matthew 25:31-41-46). Some scholars indicate they believe that the "outer darkness" (Matthew 22:1-13-14, Matthew 8:5-12-13, and Matthew 25:14-30-30) shares the same place as the LAKE OF FIRE.
This is the SECOND DEATH, the LAKE OF FIRE.
This SECOND DEATH is confirmed for the list of non-believers in Revelation 21:8. This is a permanent DEATH. There is no escaping it. The LAKE of FIRE was prepared for the devil and his angels (Matthew 25:31-41-46). Please note that the discussion of God's economic principles are intimately tied to this LAKE of FIRE. Those gatherings of believers who do not implement God's economic principles run the risk of participating in this SECOND DEATH! It is not a coincidence that much of the discussion about the harlot refers to the world's economic principles (Revelation 18:1-3-11-15-19). Furthermore, the smoke seen in Revelation 18:18 may well be the smoke coming from the LAKE OF FIRE!
