I see a couple of problems with your thinking. First, there is a difference between when Jehovah uses a person or organization for his purposes and when he claims them as his own organization or follower. The bible tells us that Jehovah through his Son will seal his chosen ones in the future but that sealing has not yet happened. Anyone can claim to be anointed in this time period and we have no idea if that is true or if they will remain faithful. That is why God’s word tells us to put them to the test.
Second, the bible itself tells us that the publishing company called the Watchtower will be discarded as it has served its purpose.
Isaiah 30:13-14: “So this error will be for you like a broken wall, Like a bulging high wall ready to fall. It will crash suddenly, in an instant. It will be broken like a large potter’s jar, So completely smashed that no fragment among its pieces will be left To rake the fire from the fireplace Or to scoop water from a puddle.”
Perhaps some would like to say when it is time to leave and perhaps they may say some have left prematurely. But tell me where in the scriptures it condemns ones that leave too early? Or, the scriptures that say to not leave until a specific time. Leaving the Watchtower organization does not mean you have left Jehovah. Nobody, including you, can rightfully make that judgment.
Jeremiah 7:4: “Do not put your trust in deceptive words and say, ‘This is the temple of Jehovah, the temple of Jehovah, the temple of Jehovah!’“
Psalm 94:20: “Can a throne of corruption be allied with you While it is framing trouble in the name of the law?”. This scripture is talking about being allied with Jehovah. The “throne” of corruption means the rulers or judges and the phrase “in the name of the law” can be worded ”by decree”. So this scripture can be restated to say “Can rulers or judges be allied with Jehovah while they are framing trouble by decree?”. I think the answer is also found in the scriptures.
2 Corinthians 6:14-18: “Do not become unevenly yoked with unbelievers. For what fellowship do righteousness and lawlessness have? Or what sharing does light have with darkness? Further, what harmony is there between Christ and Beʹli·al? Or what does a believer share in common with an unbeliever? And what agreement does God’s temple have with idols? For we are a temple of a living God; just as God said: “I will reside among them and walk among them, and I will be their God, and they will be my people.” “‘Therefore, get out from among them, and separate yourselves,’ says Jehovah, ‘and quit touching the unclean thing’”; “‘and I will take you in.’” “‘And I will become a father to you, and you will become sons and daughters to me,’ says Jehovah, the Almighty.”
Ezekiel 34:10: “This is what the Sovereign Lord Jehovah says: ‘I am against the shepherds, and I will demand an accounting of them for my sheep, and I will dismiss them from feeding my sheep, and the shepherds will no longer feed themselves. I will rescue my sheep from their mouth, and they will no longer be food for them.’”
Here is what the Watchtower was teaching on January 15, 1974 as per their publication from that date in reasoning with people to leave false religion:
”…WHAT results when a lie is let go unchallenged? Does not silence help the lie to pass as truth, to have freer sway to influence many, perhaps to their serious harm?”
That is a principle that I have always believed even before studying the bible. And, then my study of the bible further confirmed my belief in that principle. I have left the organization. I have not left Jehovah and that is up to him to tell me that I cannot worship him outside of the Watchtower. No man can make that judgment.
Isaiah 45:20-22: “Gather together and come. Approach together, you escapees from the nations. They know nothing, those who carry around carved images And pray to a god that cannot save them. Make your report, present your case. Let them consult together in unity. Who foretold this long ago And declared it from times past? Is it not I, Jehovah? There is no other God but me; A righteous God and a Savior, there is none besides me. Turn to me and be saved, all the ends of the earth, For I am God, and there is no one else.”
