Why has this thread been allowed to turn into a debate about the Trinity?
The topic is "PROVE that Jehovah's Witnesses have the "Truth"".
Jesus said "I am the Way, the Truth and the Life." Jesus said "Jesus said to them, “I tell you the truth, unless you eat the flesh of the Son of Man and drink his blood, you have no life in you. 54 Whoever eats my flesh and drinks my blood has eternal life, and I will raise him up at the last day. 55 For my flesh is real food and my blood is real drink. 56 Whoever eats my flesh and drinks my blood remains in me, and I in him."
So, the challenge is to prove that JWs have the truth. According to the Truth's own words, to have him you need to eat his flesh and drink his blood.
Do Jehovah's Witnesses do this?
Perhaps around 10,000 of their 7 million members do. The rest are strongly discouraged to do this.
So, using that very simple benchmark, do Jehovah's Witnesses have the Truth?
No.
