But when it comes to the bigger things; life/death, blood, shunning, etc. Well, do they ever factor in the thought - 'what if I'm wrong'?
In the first century according to what I understood from the bible was that the first century christians received holy spirit which I would have thought would have been evidence and christianity grew through the years.
when my parents accepted the good news from the witnesses I think they felt they saw evidence of the holy spirit active on the anointed christians of JW in doing the preaching work in this time of the end and having an understanding of the bible.
i think that their faith came from this.
I remember the brother who studied with them saying that even if it was wrong it was still the best way of life and I think my parents enjoyed the 'truth' commenting in the early 1960's that after the meeting they felt they were walking on air.
I think there was a degree of 'what if I'm wrong' however I think this was outweighed by the what they saw as evidence of the holy spirit guiding the anointed. They never claimed to have an anointing themselves.
