God is Savior of all is the verse we are talking about here...
Savior is a title when it is quantified by all your argument becomes very shaky.
The use of the Satan analogy is completely useless to your arguement
as he is the enemy to all and does not need permision to be the Enemy.
And salvation is not by force. Eventually all seeing the truth will come to it
and HOW do they
SEE this truth?
Ephesians 2:8
For it is by grace you have been saved,
through faith—
Thru FAITH. What is salvation? SALVATION IS BY FAITH.
What is faith?
Hebrews 11:1
Now faith is the substance of things hoped for,
the evidence of things not seen.
You're version of faith & salvation is when people have died and are IN the
afterlife (see Luke 16), God is literally, visibly PROVEN where they
see God literally on His throne and are facing their inevitable, inescapable judgment!
They literally cannot say any longer that this is not the true God,
they then know that they are guilty before this God for their rejection of
Christ and have sinned.
How is that
faith?

They're going to be saying and doing anything to
avoid their fate - I'd "repent" too!
We're told to recieve Christ NOW before we harden our hearts,
OR before God stops striving with us.
In Luke 16, Proof Positive was NOT sent to the rich man's family
members (letting the dead go back to warn his family of the place
he ended up), instead he was told this:
27"He answered, 'Then I beg you, father, send Lazarus to my father's house,
28for I have five brothers. Let him warn them, so that they
will not also come to this place of torment.'
29"Abraham replied, 'They have Moses and the Prophets;
let them listen to them.'
30" 'No, father Abraham,' he said, 'but if someone from the dead goes to them,
they will repent.'
31"He said to him, 'If they do not listen to Moses and the Prophets,
they will not be convinced even if someone rises from the dead.' "
No visible proof positive of the fate of condemnation would be sent -
it could further be argued that even if they HAD such proof, it
wouldn't convince them to repent!
(it could be that even seeing God face to face wouldn't bring genuine repentance to the lost).
Judas also "repented", but Jesus said in John 17 that Judas was
the only one who was LOST - the son of perdition.
Hardly the words which describe a truly repentant man that
went on to be with the Lord! Judas met and walked with Christ -
Yet wasn't born again!
Then we have the gnashing of teeth in Gehenna. . . again, that isn't
repentance, it's ANGST and derision against God. They're furious.
You see it when God is sending judgments on the rebellious world,
even in knowing God is behind the punishments, this is their response:
- Revelation 9:20
And the rest of the men which were not killed by these plagues yet repented not of the works of their hands, that they should not worship devils, and idols of gold, and silver, and brass, and stone, and of wood: which neither can see, nor hear, nor walk:
Revelation 9:19-21 (in Context) Revelation 9 (Whole Chapter)
- Revelation 16:9
And men were scorched with great heat, and blasphemed the name of God, which hath power over these plagues: and they repented not to give him glory.
Revelation 16:8-10 (in Context) Revelation 16 (Whole Chapter)
- Revelation 16:11
And blasphemed the God of heaven because of their pains and their sores, and repented not of their deeds.
You see it right there! *CAPPING* MEN KNOW GOD IS BEHIND THE JUDGMENTS,
YET BLASPHEME HIM INSTEAD OF REPENTING.

These aren't repentant people even when they know God is true.
How much does it take to prove that people do not love or want YHWY?
Sorry but there is just too much overwhelming evidence that
contradicts universal salvation -
it far outweighs the manipulated verse phrases we find taken out
of their context so often.
Again, you NEED to produce this doctrine where it's clearly taught -
you need it to be defined at the end of Revelation in the
chronological account of judgment and restoration of the creation.
Sadly for Universalists, it just doesn't exist anywhere but in
sentences that get 'read-into' to make it mean what they
want to be the truth.
