Formerbrother,
It's 2016. No one needs to go door to door to announce Jesus as Messiah. Lolz!!! Maybe some uncontacted tribes in the Amazon but you aren't allowed to bother them for fear you might sneeze and kill them all.
Also, the Mormons are coming to tell people something completely different from the Bible. Whilst JWs are simply bothering mostly Christians.
Unlike the 70, you can't heal anyone or cast out demons. Actually in Luke 10, he tells them NOT to go from house to house.
