This comes to the citation of Hebrews 10, and again I’m glad I’m not the one having to insult the sacrifice of Christ by claiming that God annihilates anyone for whom Christ died, or that Christ’s sacrifice was too small to include some sinners! Be that as it may.
I assume the point is the reference to Isaiah 26:11, where the fury of the fire shall consume the adversaries, and in v.14 God declares that “the dead will not live and the shades will not rise, therefore You [speaking to God] have punished and destroyed them, and You have wiped out all remembrance of them.”
Well, whatever it means for those rebels to not live or rise, for their remembrance to be wiped out, it must include what God prophecies in Isaiah 25 to be the result of all this overthrow and defeat: “Therefore a strong people will glorify You; cities of ruthless nations will revere You!”
And that happens to fit the second half of Isaiah 26, too, where after stating earlier that the dead will not live and the shades will not rise due to the punishment and destruction from YHWH (a fire of fury that will consume the adversaries or satans), the same punished ones seek YHWH in distress as a pregant woman in labor who can only bring forth wind, admitting that they could not accomplish deliverance of the earth nor give birth to the inhabitants of the earth (like God can and does). The result of their repentance? “Your dead will live! Their (or My) corpses will rise. You who lie in the dust, awake and shout for joy, for your dew is as the dew of the dawnlight, and the earth will give birth to the shades!”
That’s referring to rebel Israel slain by God with the fury of a fire consuming the satans (a warning the Hebraist is using about Christians here backsliding into trodding underfoot the Son of God); but God did the same thing to the ruthless nations in Isaiah 25 and brought them back, too, as loyal servants now repentant.
St. Paul thought this was so great, that Isaiah 25 is one of his two cited texts at the end of 1 Cor 15, to encourage us that our evangelical work in God shall never be in vain! (The other text is from Hosea referring to rebel Israel instead of the pagans, also similarly to Isaiah 26 promising that death and hades shall devour them and God shall never raise them again – before God does raise them again, repentant and reconciled to God and to the victims of their injustices. Thus Paul, looking forward several verses to this victorious evangelical resurrection turns the call upon death and hades around as a taunt to them.)
Sooooooooo, yeah. Not in the least a testimony to God annihilating sinners out of existence. If anything it’s a testimony that if it ever happens to look like this is what God is saying, He means something else which results in salvation for the punished ones even after death!
