I learned how to read at the age of 4 by sitting in on bible studies with JWs that my mom had. My dad introduced her to the religion. I still can say that I love each and every one of the brothers and sisters that I have met along the way and that have helped me understand the bible and teach me how to really study the WT and scriptures which helped me in life then and still. (Notice I said WT and scriptures. Cause They don't study the Bible in its correct and intended context).
With that said no matter how much knowledge they have and how disciplined they are, they lack one thing. The personal relationship that they pledge to have with Jehovah. The reason they lack it is because the Bible teaches you that if you deny the son, the son will deny you in front of the Father. They also make the son equal to the devil rather than equal to the Father. They refuse to accept the new testament and they won't read it straight cover to cover and discuss it without the material directed by the GB because they have more fear of the GB than they do of God.
It is sad. But remember that the devil knows the word well and he will always use it to mislead people. He tried to use it against Jesus and Jesus is the Word. Shows how bold he is.
The devil is the master of confusion and trickery. Holy Spirit is something that each and every one of us will gain once we have an understanding, accept Jesus as our savior and declare that we will live our lives for God and not ourselves. The scriptures state that John while in the womb had the Holy Spirit.
The Word speaks for itself.
