Most Jehovah's Witnesses believe they worship Jehovah directly, and the organization is merely an 'instrument' or tool used by Jehovah God. They 'flee' from idolatry when it comes to owning any religious symbol of devotion.
They are not allowed to own a cross, a religious picture, symbol, image, or any statue that represents God. Even a hint of idolatry in any form, is not acceptable.
However critics believe they don't see the most glaring evidence that they could be in serious violation of Jehovah's law. Their salvation depends upon their relationship with the organization. Loyalty to their modern day visible organization is a requirement and symbol for everlasting life.
If you answered 'Yes' to the above five questions, you don't have a direct relationship with God.
Christians worship God directly and receive everlasting life by being faithful to Jesus alone.
No Watchtower publications are required to understand God's will.
The Bible says that Jesus is the path to eternal life. John 6:67-69. The Bible also says that Jesus is the mediator between God and man. (The belief that Jesus is a mediator between God and 'the slave', i.e. the Watchtower organization, is not what the Bible says in 1 Timothy 2:5 NIV See What The Bible Says About The Faithful and Discreet Slave?)
The only publication Christians need to study is their Bible. And we don't need the 'entire' Bible either. Only the words of Jesus are important because only Jesus is the path to eternal life. John 6:67-69. (We recommend the NIV Study Bible or any other Bible that highlights the words of Jesus in red. The Jehovah's Witnesses Bible, the New World Translation, NWT contains these serious errors and omissions)
