I agree in that 70% of dubs think it is not true or have doubts as they are in for the social aspect...
The proof in that is in each cong you have a hardcore select who lap up every meeting and are out on field circus every week...they are about 30%...the other 70% attend every so often, go out on the ministry just for the coffee and chitchat...it is obvious to me when I was in.
IF they all did believe it they would all be pioneers...
But I will tell you that the GB and the higher echolons in Bethel believe it al 100%...as Don Cameron says in his excellent book...they are "Captives to a Concept"....that concept is that God has chosen them to be His channel of communication...no matter what!
