Baha’u’llah already did that. He communicated to everyone and explained who God was. People can go and read that
if they want to know.
No, it does not prove that belief is unreliable; it just proves that everyone is confused. Baha’u’llah explained why so many people are so confused about God.
“What “oppression” is greater than that which hath been recounted? What “oppression” is more grievous than that a soul seeking the truth, and wishing to attain unto the knowledge of God, should know not where to go for it and from whom to seek it? For opinions have sorely differed, and the ways unto the attainment of God have multiplied. This “oppression” is the essential feature of every Revelation. Unless it cometh to pass, the Sun of Truth will not be made manifest. For the break of the morn of divine guidance must needs follow the darkness of the night of error. For this reason, in all chronicles and traditions reference hath been made unto these things, namely that iniquity shall cover the surface of the earth and darkness shall envelop mankind. As the traditions referred to are well known, and as the purpose of this servant is to be brief, He will refrain from quoting the text of these traditions.” The Kitab-i-Iqan, pp. 31-32
Many people do not seem to understand His Writings so I will explain what that means.
It is because Baha’u’llah has brought a “new” Revelation from God that people are oppressed (confused about God). What happens is that when a “new” Messenger of God comes and releases the Holy Spirit into the world, it revitalizes everything and it causes people to embark upon a search for God. But
first they will make a lot of mistakes
(the darkness of the night of error) before they finally realize what the Truth is. They will learn from their mistakes and that is how they will be led to the Truth. There are many people doing that right now... The RF forum is proof of that.
I agree that just because a huge amount of people believe in something that does not make it true; that would be
the fallacy of argumentum ad populum, appeal to the masses to determine if something is true. The masses are not all that bright.
Actually when it comes to religion, at least when the religion is new, very few people believe in it. But that does not mean it is not true.
Homeopathy is not a good example, because it is still relatively obscure compared to conventional medicine. Not many people use homeopathy but that means nothing, because what people “believe in” is no indication of what is actually true or valuable. Homeopathy saved my life after I landed in the ditch and almost died from conventional psychotropic drugs. After that I got a degree in homeopathy to complement my counseling psychology degree. For personal reasons, my plans to start a practice never got off the ground, but I would swear by homeopathy, at least for what it is able to do for mental-emotional problems... I never used it for physical diseases because I never had any.
As for astrology, I think that there is something to it; it is not just superstition as some people think. My brother is an astrologer so I know something about it.
