Do you have an answer for my question? If not, keep investigating and learn what Baha'is believe. It's more than just peace and love.
But then, what about you? You believe Fundamental Christians are teaching the truth about God and Jesus? If you can't question the beliefs of other religions, then how are you going to determine if it's true or not?
How about Joseph Smith and him talking to the angel Moroni? Who told him where to find some golden plates and how to translate the writing on those plates, and those writings became the Book of Mormon. You believe all that? Nice people... They believe in peace and love I'm sure, but is their religion based on truth? Or... was it made up?
Then Baha'u'llah, did an angel speak to him too? Did God speak to him directly? And just because he speaks of peace and love, does that mean everything he said is true? Maybe, but if the Baha'i Faith is true then what all the other religions in the world today are believing and teaching in one way or another, isn't true. And if you don't believe that, ask them. Ask them which other religion today, in what they teach, believe and practice... is true and absolutely true and compatible with Baha'i beliefs.
