This sounded like back and forth banter between two equally intelligent people.....no winners in the debate.
However, I'm sure some seeds were planted. Whether or not they grow is another thing.
I truly believe most of the old-time JWs are just plain afraid to quit now. They think they are undergoing the FINAL TEST.
I'm sure if I were still a witness, that is the way I would be thinking: "This is Satan's way of trying to put a chink in my spiritual armor.
I've got to withstand the temptation."
