historian - I'll pray for you.
I'm afraid I can't connect to your feeling. I've always felt a connection to God, even when I was struggling with Catholicism/Christianity/organized religion.
My sense is that your review of the Bible verses, and the teachings of certain preachers, is hitting your confirmation bias. You're kinda literally finding what you are seeking: proof that you don't have "it."
You were created with the opportunity to have "it."
And, to echo a bit of what Jetta's stated, many of those who we would view as having lived VERY devoutly expressed disappointment with their failings. There's a phrase that currently escapes me for it, but the idea is that our human fallibility can partially blind us to how we DO have "it."
I don't know...maybe I wasn't created to have it. I might have been created to not have it. And trust me. I don't read Piper to get confirmation bias. I really hate reading Piper. It is such a slog.
