Satan owns every religion on this earth except for the one that has the faithful slave that Jesus appointed
So, what you're saying is that Rutherford's schism from Russell's teachings is exempt from belonging to Satan? Yet, the religion that Jesus started, was completely taken over and disappeared completely for over 1800 years? I guess you're saying Jesus' religion didn't have Holy Spirit backing it, but Rutherford's does.
Actually, it's pretty obvious that as soon as Jehovah's Witnesses officially became a denomination, it started going downhill. The centralization of power and doctrine is what ruined Jehovah's religion. He warned them about having kings, but the Jews wouldn't listen; next thing you know, there are altars to Baal and "sacred poles" all over the place; eventually you end up with Pharisees making up their own rules. Jesus' Christianity, and the Bible Students both were brought down by centralization of power and doctrine. The Governing Body is just the JW version of the Catholic Magisterium.
It took human church leadership to get people to buy the Trinity and Hellfire doctrines and it takes human church leadership to convince people of a "Governing Body" in Jerusalem and a "faithful and discreet slave" of human overlords. I'm not saying you should leave the Witnesses - I won't - just cautioning you not to put your faith in the men in charge, the organization itself, or its literature. All of that belongs to Satan, just like the Pharisees even though they were in Jehovah's house.
Over and over, God's true followers have had to choose between their group and their God. Be careful not to confuse the two. "God's organization" made a golden calf. "God's organization" rejected and killed Jesus. "God's organization" started the Inquisitions. The Society exists for the same reason every other church exists: To confuse people. Most churches use false doctrine to confuse people, while the Society's version of confusion is to blur the line between following God and following men claiming to represent God, and they have 7M people fooled. Get rid of the hive mind and have a personal relationship with Jehovah and Jesus. We must each bear our own load and the only place following a group has ever led was into sin.
The Watchtower company has people convinced that a group is our salvation. They have people convinced they are a modern-day Moses, leading God's people to the promised land. Jesus said the Pharisees sat themselves in the seat of Moses. If you don't see a huge and growing pile of very frightening similarities between the Governing Body and Pharisees of Jesus' day, you're completely blind or have never read the gospels.
