This is precisely the same circular reasoning that supports all blind faith...
First you choose a religion and declare its founder infallible. Then you examine the writings to see if it has anything that might look like a prophecy. Then you look for any possible correspondence between the prophecy and known historical events. If you find it that proves the infallibility of the founder, if not it simply means either it hasn't happened yet or we lack the faith and spiritual insight to interpret it correctly. Either way the founder remains infallible. Christians have been going round this circle for 2000 years. Baha'is have got a very long way to go yet. I wonder if they'll have the same stamina.
The Bahai teachings are the life of this age and being adopted all over the world. They are relevant and needed.
Look around you. We need unity between nations and races and religions. The Bahai teachings are a promotion of a prejudice free attitude towards our free low human being.
I be,Ive in the teachings of Baha’u’llah because they are relevant to the needs of today.
