Every church teaches this. How does your "regeneration" differ from others?
It doesn't
I believe that you too are a 'Calvinist' in all liklihood, but were just not familar with the term. - It is not universally used; some avoid the use of labels because they tend to be self-limiting.
Perhaps you mean that all true Christian churches teach this. "My" regeneration is based upon a Biblical understanding of the true state of the unregenerate man. However, all true Christian churches teach that a man must be born again to inherit eternal life.
So, when you die, what next? Will your self-awareness simply fade into oblivion or will you persist for all eternity? Your choices today will determine what will be your state for all eternity.
