The OBVIOUS follow up questions for any JW after that paragraph is:
"Ok, so why should I listen to you about bible doctrine?"
"If you make mistakes, should you enforce strict rules that you can't be sure are right?"
"Why do you make laws about matters of sex, marriage, health, clothing... that should be up to the individual?"
"Do you have the right to kick people out of the organization because they do not follow your instructions, though you have made many many changes (been wrong) of the decades, and now say that god doesn't talk to you?"
