What Major Intellectual Issue Most Keeps You From Accepting The Christian Narrative?

[DLJ]

To put it shortly, the claims of Christianity presuppose that God exists and intervenes in reality.  I haven't seen any good evidence or argument for that presupposition, so I can't accept it. And any particular tenet of the Christian religion requires that presupposition first, so I can't accept any of those either.

I think you are forgetting all the Nobel Prizes for Science awarded to the many and various interventionist deities.

And think of the pressure those deities are under to ensure that each and every scientific experiment came out with consistent results. I mean, once you've intervened once, you have to keep doing it in the exact same way every time.

Credit where it's due.
