Did God really say that . . . Does God really not approve of same-sex marriage? Does God really not want you to celebrate Christmas and birthdays? Does your God really expect you to refuse a blood transfusion? Does a loving God really expect you to avoid association with disfellowshipped loved ones?’
This is a very filthy tactic of Watchtower. With this paragraph they equate valid questions that each believer should ask themselves with Satan's question.
People should ask themselves 'is what I believe really true?' and then do proper research to find out.
Watchtower wants people to reject the questions right away and then make themselves believe without doubt.
All that has nothing to do with reasoning. It's just silly and unwise.
