Theistic Uncertainty

I find myself so uncertain what to believe. What is true and what isn’t? I find myself rationalizing religious texts and considering the logic of scientific theory. I see a vast Universe with holes in explanations, both theistic and secular. I want to believe, and yet I suffer from both the inability to accept things on faith alone (without rationale) and, I think, from reluctance due to sadness regarding my own abilities and station.
