So that's a slightly more coherent explanation for you and in my experience it's closer to what more critical and thoughtful Christians believe.
I've not yet talked to a believer who could satisfactorily answer whether babies/young children enter heaven if they die before their brains develop sufficiently to deal with the concept of God though. I'd be grateful if anyone could provide an answer to that one?
They just picked it because it was the funniest number they could think of.
It created its own nerdy significance.
