How do you know? Maybe if you studied the Bible you'd end up believing in it. :-)
It turns out that you actually can induce subjective experiences in yourself that I believe are similar to what religious people describe as "feeling the presence of God". It's an interesting and worthwhile exercise (though not what we do in my study group, that's a more academic format). But it's worth doing at least once in your life. It actually feels pretty good, not unlike taking certain psychoactive drugs.
Like a lot of atheists, I have studied the bible. My parents had me confirmed as an Anglican in my teens (ironically one of the first steps that took me from "I don't know if this is true" to "this particular religion is patently false").
It's impossible to understand western literature without a decent working knowledge of the bible (although choosing which one is problematic in itself), it's useful for that alone.
However, studying the bible made me less religious, not more.
After 20y of trying I'm done with mass hysteria, "you're holding it wrong", survivorship bias, and magical thinking. Give me consistently repeatable, experimental evidence.
Erm, the only way to know that is to put every effort you can into becoming a deist. "Every effort" is a lifetime of work, so you haven't done that, which makes your statement a statement of faith.
It sounds like you've already decided that you will never be a deist, and so you never will. How is that different from religious belief?
It's different because there is one less thing I have to invent. You might as well ask somebody to believe in a giant hamburger that circumnavigates the earth that only the truly faithful can see. I know you don't see the giant hamburger because you just haven't tried hard enough.
