Most sci-fi writers do seem to be indifferent or even sometimes hostile to God. Despite that, some of them are still great, at least in my opinion.
R.A. Lafferty, Manly Wade Wellman, Cordwainer Smith, Walter M. Miller Jr., Gene Wolfe, John C. Wright and of course CS Lewis are some really great exceptions that incorporate their belief wonderfully into their work if you want to ever give it another shot.

I love John C. Wright (most of the others too, but Wright’s a pretty recent discovery). I don’t know if you follow his blog, but after exhaustively dissecting “The Last Jedi” and what he didn’t like about it, he seems to be launching his own take on Star Wars. I very much enjoyed the preview I read of it.
