Easy. God, being the Creator, can do whatever he wants with his creation. If he chooses to create orangutans and not give them eternal life in heaven after death, he can do the same with any human he doesn't choose to forgive for sinning against Him.
That's what I find, beyond any reasonable attempt at reinterpretation, in Romans 9.
Paul uses and expands on Malachi's “Jacob I loved, but Esau I hated" making it clear that the issue is not one of Esau's behaviour, but of God's sovereign will:
“I will have mercy on whom I have mercy,
and I will have compassion on whom I have compassion.”
It is repeated.
"Therefore God has mercy on whom he wants to have mercy, and he hardens whom he wants to harden.".
(it does not appear that He wants to have mercy on everyone...)
"God chooses" is unmissable in Pauls message.
"Yet, before the twins were born or had done anything good or bad, in order that God’s purpose election might stand:"
This is the chapter where Paul compares humanityto mere clay, do be done with as the potter wishes, (and no complaints or come-backs.). Including those made, chosen to be "vessels of destruction"... Shaped from their start to be wrecked.
The whole extinction of the dinosaurs was settled before they appeared.
This fits with the opening of Ephesians where those who were to be Christians are declared to have been picked before the earth was even made.
Chosen and predestined.
So it's all about God's will, and whatever God does is right.
It's Potter's Right's, Creator's Rights, Deity's Rights.
Like diplomatic immunity only much more so.
If Paul and the bible are right.
Now, what am I going to choose to believe?
Though if Paul and the bible are right I have no real choice, whether I turn theist or atheist... It'll be what God wanted.
I used to believe Paul was right.But the more I read and studied the more I found seemingly sound reasons not to believe.
So unless I'm being "got at" and being made an atheist, that is my choice.
And as an ex-theist I'm hardly ruling out the possibility beforehand.
If God exists, God then knows what it would take to make me a believer. There's no impossible barrier, and "show me why I shouldn't accept what I've found out" was a regular prayer for a couple of years.
So..I think I have real choice. And that, subject to new well-tested evidence, I've made a reasonable and sound one.
After all, I'm betting my life and hypothetical afterlife on it.
