The Watchtower Study of this week (15/2) is entitled 'Jesus Christ - The greatest missionary'. Compare the following phrases on the modern-day identity of Jehovah and Jesus:
As one of Jehovah's Witnesses, however, you likely think of the missionaries sent out by the Governing Body to preach the food news in various lands around the earth.
Concerning his heavenly Father, though, Jesus Christ said: "I am a representative from him, and that One sent me forth." (John 7:29) In an expression of great love for the mankind, Jehovah sent his only-begotten Son to the earth.
In the remainder of the article, Jehovah God may be substituted by the Governing Body, and Jesus Christ may be interpreted as the class of 'missionaries'.
Another example:
Before present-day Christians are sent out as missionaries, the Governing Body arranges for them to be trained.
Did Jesus receive training? [...] Regardless of what Jesus may have learned from his mother, Mary, and his adoptive father, Joseph, he received his principal training for the ministry from the highest Source. Concerning this, Jesus said: "I have not spoken out of my own impulse, but the Father himself who sent me has given me a commandment as to what to tell and what to speak." (John 12:49)
Taking into account the equality of the GB and Jehovah, God the Father, one may easily recognize the ambiguity of this recommendation:
In contrast, what Jesus spoke was not of his own originality; he stuck to God's word, or message. That is also what we need to do.
It's, however, not clear what we need to do: stick to God's word (literally, the Bible) or to GB's word (figuratively God's word, i.e. WT literature)? Obviously this article hints at the latter but doesn't have to pronounce it explicitly because most JWs already implicitly know God's word (NWT) and WT literature originate both from a higher source, the Governing Body.
