Hi Ben. You have a fortunate background, being raised apart from thinking the majority of our neighbors are going to hell for either making bad decisions or not being one of the few lucky chosen.
I don't mean to pick on you as I accept all the ALL's, but we should probably give a nod to the scriptural specific exceptions. For example I do not believe any parts of my current organic body soon to be dust in the wind will be reconstituted to eternal organic material, and quite frankly don't see the need for that. As it is with many things in temporal creation.
And then, a bigger theological question, Satanic salvation. Even though I am a universalist when it comes to people I am also a universalist in reverse fashion with Satanic salvation i.e. the devil ain't going to be saved or converted, but simply set aside and put away forever. And I'm good with that. An antiLife spirit can serve temporary purposes FOR GOD no less, and not have a place in eternity, nor does it have to have a place in eternity nor does it have to be reconstituted to be something else.
As your own "all's" citing could factor in, technically we are dead, and our life is hid with God in Christ. I don't think that changes after our physical death. Col. 3:3. We will in fact remain dead as we are currently, and contrary to what we temporarily think. Not that that is all that is going on currently, mind you. I believe God's Life and the working of the adversary are still very much in play within all people.
So technically a part of everyone is in fact going to HELL. Which is not a commonly realized matter.
All have sin. Sin is of the devil. Yes believers, we do carry very certain things to permanent final adversarial judgments. All of us serve God in this way as well. Some obviously more than others. Depends on how much dragon meat they ate at the distribution meal before they got here.
Isaiah 43:20
The beast of the field shall honour me, the dragons and the owls: because I give waters in the wilderness, and rivers in the desert, to give drink to my people, my chosen.
Dragons, beasts and owls are obviously association terms for devils. And we get relief from God's Waters because of their actions in us, so as not to overwhelm us either with their ill works or in a converse manner, God's overwhelming glory.
Psalm 74:14
Thou brakest
the heads of leviathan in pieces,
and gavest him to be meat to the people inhabiting the
wilderness.
Which then resulted in this state for everyone:
Romans 11:
32 For
God has bound everyone over
to disobedience so that he may have
mercy on them all.
The "spirit of disobedience" is an exception to the ALL. It is not the same as "everyone." Just as the sin and evil present within Paul, that Paul dealt with was "no longer I", Romans 7:17-21 He saw the difference between himself and the devil that was in his own sorry hide, 2 Cor. 12:7, that temptation that was in his own flesh being of that tempter, resulting in the state of Gal. 4:14, causing his flesh to be at odds with God/Spirit, Gal. 5:17.
Besides all that, promoting Satanic salvation is simply not a good message, if you fast forward that kind of thinking and what could become of it. We don't need to put that bad actor on center stage, as much as it desires to be so.
