20:10And the devil who deceived them was thrown into the lake of fire and brimstone, where the beast and the false prophet are also; and they will be tormented day and night forever and ever.

And THE DEVIL who DECEIVED them was thrown into the LAKE of FIRE and BRIMSTONE,

THE DEVIL FINALLY IS FINISHED!

We could have thought this time would never come, even though Jesus already told us that this place of eternal fire existed for the devil and his angels (Matthew 25:31-41-46).

The devil, thinking he is as great and powerful as the Most High (Isaiah 14:3-14-21), ends up so low. The people he deceived were burned or destroyed physically and spiritually from above in the previous verse. And here, the devil, himself joins them but is burned from below. We aren't told who threw him into the lake of fire and brimstone, but given the skills and deceptive nature, it had to be a very powerful angel or Christ Himself.

where the BEAST and the FALSE PROPHET are also;

These two henchmen of the devil have spent the last 1,000 years in this lake already (Revelation 19:20). The sentence uses the verb "are" implying that they still are very much alive. This phrase indicates that everlasting life does exist for evil ones too. It just isn't the pleasant standard of living that the believers are enjoying!

and they will be TORMENTED day and night

The "they" here specifically means the Unholy Trinity, the devil, the beast and the false prophet, are being tormented. But it could be used in a much broader sense as Revelation 14:9-11, and Revelation 20:14-15 where the non-personal, death and Hades, also are thrown into the lake.

FOREVER AND EVER.

This same expression is used in three different contexts throughout the Revelation. If FOREVER AND EVER is a GOD quality, then the TORMENT of the devil will last as long as there is a God.


FOREVER AND EVER.
Revelation 1:18 and Revelation 11:15
Christ's Eternity and the length of His reign.
Revelation 4:9-10, Revelation 10:6 and Revelation 15:7
God's Eternity
Revelation 20:10 (this verse)
Length of residence of devil, beast, false prophet, and those he deceived.

The use of "day and night" in a literal sense implies that the sun will be around FOREVER AND EVER. This causes a dilemma for science as most astronomers indicated the sun will last another 5 billion years or so. While 5 billion years or so is a long time, it is not FOREVER AND EVER. Thus we must conclude that this expression means everlasting or without end and probably applies more so in the spiritual sense.

An aside note: The paragraph above presents a simplified view based solely on the estimated atoms that comprise the sun. What is missing is the interactive elements: galactic dust and galactic electromagnetic waves. Both of these together could cause the Sun 'to micronova'a. These waves cycle approximately 12,000 years apart. If the sun micronova occurs, the earth will go through many geologic changes depending upon the direction and force of the sun's micronova.
