The WTS's self supporting marketing strategy ....
Claim Jesus has returned and has taken position on his heavenly throne and at the same time has
chosen the leaders of the WTS. as a singular mouth piece for all mankind
Claim that they alone have the right interpretations of the bible
Openly suggest to have been deeply trained in bible theology on a academic level
Point out false doctrines by other Christian based religions and compile that as the
reason why god has left those religions in favor of the WTS.
Claim those religions will soon be destroyed as well all of its adherent followers.
Mentally indoctrinate people with doctrines that are presently expressed as the Truth by god's direction
through his holy spirit .
Carefully and methodically change doctrines when necessary (This Generation) which were once an attracting feature but over time ran out of their useful appeal.
.
Keep a close watch onto all members to seek out dissidents or opposers to these engaging doctrines which were orginally created to lure in people to the organization.
(Millions now living will never die)
.
If and when they are found , make sure they are muzzled and demonised from the rest of the other members, including family if need be.
.
Rince, recycle and repeat.
