I question.
I pray.
To me Chris Langan is saying Heaven exists because our souls are eternal, "nothing in this universe is ever wasted, nothing ceases to exist".
Since all souls are eternal, their essence in the afterlife is determined by the actions of our free will on earth. "We use our free will to create" our destiny.
This from a man with an IQ of 200 and non religious (from what little I know of him).
I found his comments interesting because at the core of my belief is that our soul is given to us from God. That all souls are eternal. And that whether we like it or not, there is no opting out.
