Further re 2 Thess.1:9, Jason Pratt said:

"Which definitely refers to hopeful punishment (and expected salvation in the same day of the Lord to come), not annihilation, when Paul uses it to talk about handing the Stepmom-Sleeping Guy over to Satan for the whole-destruction of the flesh in 1 Cor 5:5.

"Paul compares it to a birth-pang, which is dangerous but hardly hopeless annihilation (and is generally regarded as very hopeful) at 1 Thess 5:3 (talking about the same day to come).

"Paul uses the term to describe people killed by God in the past at 1 Cor 10:10, which can hardly be annihilation unless the resurrection of the evil as well as the good is denied.

"2 Thess 1:9 uses phrases similar to those found in Isaiah 2, talking about the same coming event, which is part of a block of prophecy where those wholly ruined aren't annihilated, but eventually repent of their sins and go to the "survivors" of God's wrath to be reconciled to God, which God accepts washing

them clean with spirit and with fire. (Isaiah 4.) Again, far from a result of hopeless annihilation.

"2 Thess 1 is actually one of my scriptural testimonies 'for' universal salvation."
