It is not a claim, it is a belief. Baha'u'llah made the claim and I believe His claim.
You've explained that you have this understanding of how those words are used such that something can be called a belief but not also a claim, but others use them differently. Your words are understood as you claiming that the words of Baha'u'llah are true, which is you claiming that they are true as well. No distinction is made between you saying something is true to you and you saying that you believe that that something is true.
Did Baha'u'llah make more than claims? Not in my experience reading the citations you and others reproduce here. What I see are vague, lofty exhortations, not evidenced arguments. Even so, if you believe his claims and repeat them as something you believe, it is your claim as well, even if it wasn't original to you. Whether you have good evidence or not doesn't change that, just the nature of the claim in the spectrum of unsupported claim to a claim that is the sound conclusion of a valid, evidenced argument.
You don't need to say that that's not how you see it. You've made that clear. Hopefully, so have I made myself clear enough for you to understand that whether you agree or not, which isn't relevant to others.
If God decided everything we would be and do we would be programmed robots.
Another poster correctly identified that finding an outcome undesirable is not an argument against its correctness.
We very likely are what you call programmed robots, if by the self we mean the observer within the theater of consciousness and not the material reality outside of consciousness that supports it and is one of its objects. All of our thoughts are generated in neural circuitry and then delivered to consciousness to be discovered and obeyed. The idea of the self being the free source of those thoughts is incoherent, because that's the role of neurons.
Maybe by robot, you are envisioning something with less that human consciousness, maybe unconscious like the robots in old sci-fi like Lost in Space, Forbidden Planet, and The Day The Earth Stood Still, or something half comatose like a zombie. If so, the word doesn't apply, as we are clearly not that. But if a fully alert but deterministically functioning organism that experiences a series of imperatives delivered to awareness and complies with them can exist - and there is no reason to think that any other kind of conscious thing can exist - then we are likely that. Think more like Data on Star Trek.
Would that be a setback to discover that that was the case if it were? It would be to the religions that consider perdition a just punishment for disobedience, but how about you?
Not me. I've already assimilated the possibility and likeliness, and guess what? Nothing at all changes.
I cannot prove that the premise Baha’u’llah was a Messenger of God is true.
Nobody expects you to prove your beliefs, just support them sufficiently to justify believing them if you can. If not, your beliefs are of little value to critical thinkers, and are understood as belief by faith, the only alternative to belief following sound, evidenced argument.
To lead us unto all Truth about Life and Death.
I asked, "What's the use of the god you describe?" Here you are again with another private definition, this time
truth. You have no truth by my definition of the word, just unfalsifiable claims. So, to translate into my usage, the value of this god is to make unfalsifiable claims through a messenger.
Below is what Baha’u’llah wrote about the 'evidence' that establishes the truth of His claims.
Whatever followed would fail at that, unless his claim was one involving only pure reason like the proof of the Pythagorean equation, but it is not. It is a claim about what actually exists outside of minds, and like the Christian Bible, all other scripture, and all other writing about our common reality, none of it establishes the truth of anything about the world. This why the messages of messengers are rejected by critical thinkers, because they are only words like those human beings frequently write, which is evidence that a human being wrote them and nothing more - not even evidence the authors believed them.
