20:11-15 How are we to understand the great white throne judgment and the lake of fire?

The great white throne judgment and the lake of fire signifies the end of Christ's millennial reign pursuant to Him handing over the kingdom to God (cp 1 Cor 15:23-28). The great white throne judgment is when all the ungodly, from the beginning of time to those killed by fire from God at the end of the thousand years, in the last great rebellion led by Satan, are cast into the lake of fire.

The lake of fire is the final destiny of the wicked - a place of torment, into which Satan and all the fallen angels, Antichrist and the false prophet, and everyone whose names are not in the book of life will be cast at the end of Christ's millennial reign (cp Rev 14:9-11; 19:20; 20:7-10; 21:7-8).

Those not found written in the book of life who will be cast into the lake of fire include the tares and the nations condemned by Christ for their failure to extend mercy to the Jewish believers during the tribulation (cp Mt 13:24-30; 25:34-40 with 41-46 (see also comments on Mt 13:24-30 and 25:31-46).
