Goingthruthemotions Ask her this:
If Jesus got married, what sort of a husband would he be?
Obviously he remained single. So what sort of a husband would he approve of? What sort of husband do you think the modern day GB make?
If she says "good husbands, loving, faithfull in sickness and health" etc, say you agree.
Then tell her about Judge Rutherford deserting his disabled JW wife and son and not seeing them for over 20 years...that they didn't even attend his funeral. (actually he even had a mistress, check out JWfacts.com)
Then ask if she thinks Jesus would choose such a man to lead his people on earth...
