I found this interesting perspective on reddit.
I remember the moment the first real crack in my faith happened as a Jehovah's Witness.
I was sitting in the Kingdom Hall during the Watchtower study where, as is common, the article was talking about how the Israelites as a nation abandoned Jehovah.
"But wait," I thought, "Having a nation represent him here on earth was part of his plan. If they abandoned him, then his plan failed."
This thought spiraled into further epiphanies.
"Adam and Eve and the Garden of Eden. That plan failed too."
"Having a heavenly family where everyone worships him. That plan failed."
"Ridding the earth of wickedness during the flood. That failed."
"How reliable is Jehovah? His plans never seem to go as intended. Will his plan of Paradise even work? What about his 'earthy organization?'"
These were some doubts purely from a theological perspective as I had already had a few from a scientific one. Watchtower always said to research in their publications when you had doubts, but as these doubts grew and splintered into new ones, I was finding the publications just didn't have the answers.
When someone is truly honest with themselves, they don't continually try to prove to themselves that something is true when they have already verified it is false. Watchtower actually asks JWs to do this.
"Strengthening one's faith" and "waiting on Jehovah" are both examples. The former is asking JWs to only look at evidence or circumstances that point to Jehovah actually existing along with his grand plan for humanity.
The latter, waiting on Jehovah, is asking JWs to ignore their doubts and wait when strengthening their faith doesn't work.
And this is why apostates are so "dangerous."
When JWs find that Watchtower doesn't have all the answers, we are here to say, "You are not crazy for thinking this way. I had that doubt too."
Our only threat to Watchtower is simply validating the thoughts that current Witnesses already have.
When I first found this sub, I wasn't flooded with new information to take away my faith.
I was simply told I was not crazy for thinking the way I did, and that went a long way in helping me to be mentally free.
Watchtower has it wrong.
Most doubts aren't created by apostates. They are created in a Kingdom Hall.
