Welcome to the board !
Just a minor point.....JW use Prov 4:18 that the light gets brighter and that's why the many changes for the last 140 years.
Why not read the surrounding scriptures in Prov 4 and see what Solomon was talking about.
Why would a God continue to make changes in doctrines for the last 140 years, what would be the purpose of fooling, tricking and changing doctrines.
The whole thing does not make sense. The truth is that they really don't know their left from their right.
Hope you can help your family to wake up, not get baptized and become a slave to the GB.
