The point of this forum is religious discussion and debate. If you start a thread saying, "Bob is a Prophet of God," people are very obviously going to ask you what the heck your evidence for that claim is. If you're not interested in making such a demonstration, then at least don't post in the Debates section. Stick to the Baha'i DIR section so you can just talk about your beliefs with people who already agree with you.
Yes,
what about his life, exactly? I already addressed why you can't point to his teachings, as that would be circular.
Wait, they display all the attributes of God, perfectly? This is the typical Abrahamic, omnipresent, omniscient, omnipotent God, yes? I'd love to see the evidence that Baha'u'llah was any one of those, let alone all three. And isn't God eternal? But Baha'u'llah died, didn't he?
I highlighted the key section of the passage here. So Prophets
don't necessarily display all God's attributes - but we're supposed to believe they have them, even if they show no evidence of it.
So which of God's attributes did Baha'u'llah display, and how so, specifically?
The teaching that we are "spiritual beings" is also a claim. So yes, again, his teachings are claims.
Waaaaaaayyyyy too long and too many rabbit trails to delve into all that. Hit me with your best prophecy, and I'm happy to discuss it.
