In other words if not Jehovah's witnesses then what other religion or organisation would you go to?
I would say that I have a personal relationship with God and so it wouldn't matter where I go (even though I don't really believe that anymore). I would quote the scripture where Jesus said that we are to worship in spirit and truth and it didn't matter what physical place we were at. You could also quote the scripture where it says that whenever two or more are gathered in Jesus name then the spirit would be there also. Jesus never said anything about an organized religion at all.
