If you accept the Bible as a source of facts, (and obviously many do NOT) and realize it is best to read several of them and know their differences, then one can safely say that The Most High God is identified as YHWH.
That part was easy.
If we assume that The Most High God would expect his people to teach TRUTH and follow his word, then it is obvious the WT Club is not being used by YHWH. There are plenty of recent facts to confirm that!
For me, I have adopted the mindset that God's people are not identified by a "membership card". It is a lifestyle and a heart condition.
Jehovah's Witnesses as an organization are NOT God's chosen. Are there card carrying members who might have God's favor? Perhaps...but no man on earth can read their heart to know for sure.
Only WT club elders claim to be able to know individuals heart condition...which is one more thing that identifies them as false.
