The arguments of being Unborn are all refuted by Adam. Adam was created in an eternal relationship with God.
Guess what, he fell from that relationship, he was unborn.
After Christ recreates the world through His Incarnation, death and resurrection, He is now able to give man eternal life.
However, man must take the initiative, of his own free will, to respond to God's call to come. When man answers in the affirmative, he reenters into a relationship with Christ through baptism. It is the ONLY way to get back into the relationship with God lost by Adam.
Now that you are in the same relationship as Adam was with God, did Adam fall? If you agree with scripture, then you can also fall from that relationship, in other words get unborn.
By the way, one can also get unborn physically, by suicide. Man can freely take both his physical life and spiritual life away.
Your theology is lacking reality and scriptural understanding.
