Jehovah's Witnesses are taught that all religions are false except for the Watchtower organization. However what if the Watchtower is wrong?
Jehovah's Witnesses pray to God through Jesus, but they worship him 'through' the organization. Their relationship with God is not direct. This is contrary to what Jesus taught in Matthew 28:18,19.
If you're in the organization or interested in what they believe, examine the evidence.
