Okay, for the third time this morning in these forums, I'll explain how the survey was taken. But first, an ¿honest? face to face conversation about belief is never fruitful because all of us, every single one of us will lie.
The survey was taken in the mid-eighties the Barna Group took a survey, cross-denominational of the American Christian Church. The survey was done in Double-Blind Fashion to avoid lies as much as could be possible in order to arrive at a true or as true as could be possible because they did not need to be concerned about anyone, save God, knowing how they answered.
The Test Sample was the Faithful Only and that was defined as those certified to attend services no less than three times a week by that Churches Pastor. Nobody wrote a name nor did they use any identifying marks but merely checked yes or no for each answer.
I do not know every question because I was still in the Juke Joints chasing women and playing my guitars but as it was explained to me the questions were few and of the following nature ; "Do you believe Jesus died on the cross to pay the debt for your sins? Do you believe in the Virgin Birth? Do you believe Jesus is returning on a cloud to take you to Heaven with Him?"
Now the Faithful in any given Christian Church will run someplace between 10 and 15% of that particular assembly and of that, somewhere between 10 and 15%, less than 2% believed the basic tenants of the Christian Faith.
With this result it can easily be concluded that somewhere less than 1% of the entire Church is actually saved and walks with God but I favor believing, for no good, particular reason, that the number will carry throughout even the occasional visitor.
