Well, my first experience with Christianity post-jaydub was at "the church for atheists with children".
Okay, that remark is something of a misstatement. The UUA is actually post-Christian, but it began as two separate but compatible Christian denominations: the Unitarians and the Universalists.
Anyway, the most important idea that I took away from that religious experience was universalism. I never fight for anybody else's salvation because I'm convinced it's not necessary: salvation, whatever that means, is inevitable. Or, to put it more poetically: after we die (assuming we have something like an immortal soul), we fall into, or are transmuted into, a landscape of flame and light. If you have any experience of love, it's heaven. If not, it's hell purgatory. Nevertheless, since I believe we continue to learn after we die, you can escape any time.
As far as I can see, it is only in this limited sense that "Hell is real," as my favorite evangelical preachers like to say (without ever adding any details when I was in earshot).*
