I agree with you. When I claim that:
“sinning means freely choosing to remain alone forever, i.e.: to be unknown to God”
I refer to what “ultimately” happens, that is (in your wording): “when our life is complete and we still reject God's love and live only for ourselves” and “then we do join all those who share this life style in Hell.”
Thus to be in Hell means to have no name and be “unknown” to God, according to Luke 13:27.
For the rest I like your formulations in this posting.
Nonetheless in your previous posting 224 you claimed:
Here you are referring to the first sin in human history, and claim that this sin “spread into all humankind like a virus”.
This explanation is fitting in several respects:
It accounts for the fact that all humans coming into existence after the first sin are in stage of sin, according to “because all sinned” (Romans 5:12).
This stage of sin does not arise from any personal sin freely committed but everyone gets it unwillingly like one gets a contagious illness.
Since sin is something affecting the spirit this stage of sin is not transmitted to others through biological or genetic inheritance.
Nonetheless the explanation should NOT be misunderstood in the sense that:
everyone gets unwillingly the stage of sin generated by sins other than the first one.
Such a claim would amount to acknowledge that God damages every incarnate spirit (human being) every time someone commits a sin.
If one puts all these requirements together, we are led to the following conclusion:
Only the stage of sin produced by the first sin (the stage of original sin) becomes transmitted to every incarnate spirit created after the first sin, in such a way that everyone gets this stage unwillingly.
As repeatedly claimed, in my view the reason for this state of affairs is given in Romans 11:32.
