The JWs believe they are led by God's Spirit.
God is Love says 1 John 4:16
And so we know and rely on the love God has for us. God is love. Whoever lives in love lives in God, and God in him.
Love does not look for it's own interest 1 Corinthians 13:4-7
4 Love is patient, love is kind and is not jealous; love does not brag and is not arrogant, 5 does not act unbecomingly; it does not seek its own, is not provoked, does not take into account a wrong suffered, 6 does not rejoice in unrighteousness, but rejoices with the truth; 7 bears all things, believes all things, hopes all things, endures all things.
The organization is all about looking for it's own interest. Why not see for yourself that they rejoice in unrighteousness? Which means they get happy when they think of God destroying everyone but them.
Also it is clear that they do not have truth yet they rejoice in what they do have. It is my opinion that what they do have is selfish longing. It is not bad to hope for a peaceful Earth. But it will never come the way they say which is to be like them.
I left because I came to my own conclusion that they are not beng led by God's Spirit. And it is my opinion they they are not looking to be led by God's Spirit.
