Jesus said, "I am the way, the truth, and the life." He didn't say he HAD the way, or that he HAD the truth, or that he HAD the life.
According to the Bible, Jesus IS the truth; if you know the truth, the truth will set you free.
Jehovah's Witnesses set their dogma and religion in the place of Jesus. They refer to their dogma and religion by a role that Jesus said he would personally fulfill; they call it "The Truth."
The Bible is clear that servants of Christ can be in the truth. Jesus IS the truth, and his servants are in him. However, Jesus is NOT a religion or a religion's dogma. The Bible shows that Jesus invites a personal relationship with himself, and that once that relationship is established the person who has established it is freed.
Is it any wonder, then, that Jehovah's Witnesses doctrinally proscribe any direct communication (communion) with Christ? If someone has no personal relationship with Jesus Christ—the one who IS the truth—such a person cannot possibly be IN the truth.
