How do you know he didn’t accept Christ in his life? Because he didn’t get on the mountain top and scream it. Odds are he didn’t but I don’t know if he did or not and that’s between him and the big guy. He was a brilliant man. God rest his soul.
He was a professed atheist.
A quote by the man himself:
"Before we understand science, it is natural to believe that God created the universe. But now science offers a more convincing explanation. What I meant by 'we would know the mind of God' is, we would know everything that God would know, if there were a God, which there isn't. I'm an atheist."
I think he was brilliant but the conversation he just had with St. Peter did not go the way he thought it would. He is probably muttering under his breath "How did I get it all so wrong?", and he walks into Hell.
