I discussed this issue with a MS who came to "shepherd" me shortly after I left.
I outlined how ineffective the door to door work was at getting the message over and yet people would be judged according to their reaction to the "Good News" as presented, and yet if they had never heard it they would get a resurrection, so I said :
"The best thing you could do is not say a word, just shoot the householder between the eyes as soon as the door is open "
I got the glassy eyed, deer in the headlights look , and silence that was all he had to offer to many of the points I made.
