That the fellow is talking and thinking is a good thing - some of the most passionate evangelist speakers I have heard started out as atheists and their efforts to disprove God led them to an absolute belief. Funny how that works....
He’s not an atheist; he has fixed upon a very peculiarly parochial idea of God, and of course all those ordinary Christians are just washed up and he’s the smartest person in the world.
C. S. Lewis is one storied ex-atheist who ended up not only believing, but actually laboring to come up with a unifying popular theology for all Christendom, and hence his book “Mere Christianity.”
Having gone through a number of wringers myself, I think I could well refine Lewis’s approach, or at least refit it to the current of thought in the present age. But that doesn’t make Lewis’s work itself un-useful, when taken with the salt that it needs. This also hailed back to a time when Lewis’s Anglican church was more serious about the presence of Christ than it is today, over 50 years later.
