We have made God's Name known again- when Churchianity & Judaism almost wiped it out.
Jehovah is not God's name. In Hebrew scripture the Divine Name was represented by the tetragrammaton.The closest to that in English is Yahweh. The big problem with the word Jehovah is that it is a hybrid word derived by combining the Latin letters JHVH (for the tetragrammaton) with the vowels of Adonai (which means Master or Lord). It's simply a made up name. Imagine that the translation of God's name in English was Bill and a group went round calling itself Walters Witnesses, saying that they were preaching God's name which they say is Walter whereas everyone is wrong as they call him LORD. It's irrelevant that they spend a colossal amount of time preaching - it's still a nonsense name.
Jesus foretold that in the end times the good news of the KINGDOM would be preached to the world.
The JW version of this goes as follows. Around 1914 there was a war in heaven, and Satan and his followers were cast out. Jesus Christ began ruling as King in 1914 and 1914 therefore becomes the start of the Last Days.
We don't need to even start on what the future holds. The above is all based on 607 being right. It is not. So this means the Witnesses have spent countless billions of hours preaching the wrong date for the war in heaven, the wrong date for when Christ took up reigning and the wrong date for the start of the Last Days! And peoples reaction to this unholy mess is how God will judge them as worthy of life or death?!
It's a shambles. How can this in anyway contribute to 'vindicating God's sovereignty?' How does God getting his people (or allowing his people) to preach false dates and then killing billions who don't listen to such nonsense prove his right to rule?
So it doesn't matter about Trinity's or whether other doctrines are right or wrong.
Once you've understood all of that, read up on the mess which is the Christian Greek Scriptures. And then you'll realise the whole thing is an utter waste of time.
