Switching subjects a bit here is another Scripture relevant to the discussion,
1 Corinthians 15:55, "O Death, where is your sting? O Hades, where is your victory?”
There is a textual variant here where many English translations miss the emphasis on Hades. The proper translation is important because it reinforces the hope that the gates of Hades will be defeated as is explicitly shown in Revelation 20:13.
A.E. Knoch tries to use this verse to show that the Lake of Fire will be emptied, because he understood as many Universalists that human beings will be punished in the Lake of Fire. If humans are punished in the LOF, then we need to understand how they will be removed. However, I still think the better model is that the LOF is reserved solely for the damnation of Satan and his fallen angel following, the goats on Jesus’ left.
Unbelieving humans beings, however, are punished in the temporal fires of Hades. 1 Corinthians 15:55 and numerous other Scripture warn of this punishment, but the greater hope that salvation is promised even for those suffering there.
Though I am intrigued The preterist position that Hades has already been emptied, I just cannot follow the arguments from Scripture. There seems to be a joy that salvation is completed at the cross, which it is, but a denial a remaining sin and God’s loving and just response to mankind’s sin. The victory is won, but there are still skirmishes to be fought.
