How much of the right Jesus (or the right resurrection) is enough for Salvation? The Lord will make that determination.
This makes perfect sense. The Lord will decide.
I offer my testimony as an example of how I got saved. But, I am confident that if I had not abandoned the idea that Jesus was really Michael the Archangel, I would not have been able to pray to him. Of that I'm sure. Furthermore, I never really bought into the idea that Jesus wasn't in the same body after he was resurrected, even as a JW.
I am not convinced that Jesus is the same as Michael myself. Refer to Jesus as Michael in a JW setting and everyone begins to squirm. However, it truly doesn't really matter to me if he is or isn't. It's the same team, so to speak and doesn't change anything about his resurrection.
Some things are simply above me, and if God wanted to he would shed more light on them for us.
But the 30,000 ft. view is that the enemy is definitely targeting the minimal belief requirements God has stated that is necessary for Salvation. That realization alone should be enough to warrant further reconsideration of JW assumptions (Watchtower definitions)
The minimal belief is precisely what we read in Romans.
The enemy doesn't waste time with things like what we've discussed. That's just man getting in his own way. The enemy focuses on trapping us with greed, hate, violence, self idolatry as you said, spiritism, worshipping it itself. Things like these are the real dangers.
