Does this follow? Let's have a look at it.
1. the necessity of our free will meant that the results of a free will decision must be sacrosanct in the eyes of GOD. HE WILL NOT CHANGE THEM for any reason.
That is contradicted by the many, many times in the Bible and stories from two thousand years of Christian literature in which God does interfere to change people's decisions.
Did God not intervene when he changed Saul of Tarsus from a persecutor of Christians to one of the founders of the Christian Church? Did God not interfere with Jonah's free will when Jonah tried to escape God's instructions? Was God not interfering with the choices of forty-two children when he sent two bears who tare them to pieces? When He forced Pharoah to set the Israelites free from Egypt? Have you never heard a Christian saying that they were lost in sin and God showed them the light, without them asking for Him to?
The idea that God never interferes with people's choices is flatly contradicted by Christian stories of him doing so all the time.
2. The only power that can help a person turn from the evil they have chosen is GOD's power of persuasion motivated by HIS loving grace. By totally rejecting HIM and HIS promise of salvation from all sin, the reprobate were passed over for election and left to their own devices which cannot save them from the natural and legal consequences of becoming sinful and evil in HIS sight.
Why? Why is it simply not possible for a person to see the choice, heaven or hell, and simply decide they'd rather go to heaven?
I'll tell you why: because nobody chooses to go to hell. Seriously. Absolutely nobody. You would have to be plumb crazy to make such a ridiculously self-destructive choice. I know you have to tell yourself that people do this, because it means it's their fault rather than God's. But it's contradicted by everything we know of human nature. It just doesn't happen.
I for one can tell you that I have never made such a choice, and can never imagine doing so. I mean, think about it: "Yes, please, I'll choose the roasting on a spit for eternity; it looks much more fun than hanging about on a cloud playing a harp."
Seriously: who do you imagine would ever make a choice like that?
3. If GOD were to change their minds and force them to marry HIM no real marriage could result because no true love nor true marriage can be forced, they must be chosen.
If we're going to turn this into a marriage analogy, I'm afraid it does not make Christianity look good.
Forget about the extremely dubious ethics of one person wanting to marry every person in existence. Let's go with it. How does that look for, say, me?
It's like a marriage in which you never meet the spouse, but you're assured they exist. They exist, and they love you.
No, you can't meet them, but if you do the right things, you'll be able to feel their presence and love for you. And even talk to them! Possibly.
No, not on a telephone.
No, they won't actually say anything you don't already know.
In fact, they might not even speak in words.
But they love you! Like, they really, really love you. And they want you to come and live in their wonderful home.
No, you can't see a photo of it.
No, you can't talk to anyone who's been there.
And if you don't marry them, by the way, you're
choosing to go to a really horrible place. Which the person who wants to marry you made, by the way.
That does not sound like a healthy relationship at all.
4. When we all saw the creation of the physical universe and HIS deity and power (and hell) were fully displayed, the reprobate could never by their free will change their minds because of the coercive nature of this revelation.
Why couldn't God manifest in some less titanic form that could prove the truth of Christianity's claims? Like Jesus. Or the vision to Paul. Or, for that matter, just turning up in less-than-mind-blowing form and just producing some evidence of Christianity's claims.
5. The nature of evil is to grow in the mind and desires until it is fully realized and the person is completely given over to his addiction to evil (thus called a demon) and will never, can never, change his mind about what he believes to be right in the face of opposition...that is he can't be brought to repentance but only banished from heaven.
It makes sense that you think this, because you are supporting the banishing of all humans who do not agree with you to the maximally horrible destination. And so you have to believe that they are, or will become, maximally horrible, because if they aren't, then you are guilty of sending innocents to torture, or at least of endorsing this.
But if you do believe this, you have to believe that the majority of the normal people you see around you are appalling demons-in-waiting. And it's obvious that they aren't. They're normal people, with a bit of bad, a bit of good and a bit of in-between in them. And if God is restraining them from evil - well, restraining is an interference in their free will, isn't it? You said that God will never, ever do that. But apparently, He does, when He stops humans from being maximally evil on Earth. It all sounds very confusing, and that's probably because it's a mess of contradictory ad hoc rationalisations.
Thus the result of their decision to reject YHWH knowing that if they were making an eternal mistake, they would put themselves apart from HIS loving grace and salvation forever, was realized.
None of them ever made such a decision. In the whole history of sin and sinners, nobody ever said to themselves, "I know I am evil, and it's such fun. That's why I'm so excited about going to hell, where I will be tortured in the most hideous ways for eternity."
