I personally am grateful that one woman in field service took the time to explain to me that Christians believe in a paradise earth.
I addition to explaining her beliefs about paradise earth, did she explain how she believes that everyone such as yourself who is contacted by Jehovah's Witnesses yet doesn't become one, will be slaughtered by God at the soon to happen Armageddon? This includes any children living in your household.
You may have fared better at Armageddon had she not spoken to you.
