Here's another place the Watchtower twists scripture: Revelation 1:16 "And he had in his right hand seven stars"
The Watchtower says the stars are the elders in the congregations of Jehovah's Witnesses. (The WTBTS likes to make stuff up to get people to worship them! Yuck!)
Here is what Jesus actually told John: "As for the sacred secret of the seven stars that you saw in my right hand and of the seven golden lampstands: The seven stars mean the angels of the seven congregations" (Revelation 1:20)
The stars mean the angels. Actual angels, not people messengers. At other places it says "into these things angels are desiring to peer." Angels are interested in the sacred secret too.
The "seven congregations" aren't just the KHs of the WTBTS organization known as "Jehovah's Witnesses".
"For where there are two or three gathered together in my name, there I am in their midst." (Matthew 18:20)
Jesus is the head of the congregation. "Jehovah knows those who belong to him." When the great tribulation begins, Jesus will send his angels to gather the faithful ones in true worship from wherever they are found and make clear those Pharisaical religious leader fakers who are not approved. When it says illustratively of the religious fakers that "their weeping and gnashing will be in the fiery furnace" it implies they will lose their "privileged" status in their respective religious institutions when those religious institutions are destroyed. They will still be alive enough to "weep" and "gnash their teeth" about losing their esteemed statuses.
There are true Christians in many places, and we are one family when we follow Christ, it's just some of the false doctrines (the leaven) have to be cleared out. Jesus will clear them out at the appointed time, and we will be united in spirit and truth.
Here is what the angels of the congregation will do:
"The Son of man will send his angels, and they will collect out from his Kingdom all things that cause stumbling and people who practice lawlessness, and they will pitch them into the fiery furnace. There is where their weeping and the gnashing of their teeth will be. At that time the righteous ones will shine as brightly as the sun in the Kingdom of their Father. Let the one who has ears listen." (Matthew 13:41-43)
