Yes your bible is ok to use. No you don't have to go out door to door because that's "voluntary"
My wife tried that "voluntary" thought with some business associates of hers. She explained to them that she didn't have to go out but wanted too. I explained that they always taught god would kill them if they didn't go out (blood guilty) but she would not or could not reply to me.
When the hell did they come up with this stupid reasoning. It has always been very clear that if they didn't "preach" the good news they would be blood guilty and we all know what god does with blood guilty people.
I wonder if the WTBTS has tweaked this belief so as to avoid any lawsuits if one of their "employees" is injured if out in the door to door work.
