My only intention is to provide a clearer understanding of Baha'i principles. Perhaps asking these questions in s.r.b. I would clarify this by saying that in the Baha'i view, these religions are all valid as they all come from God. But as humanity progresses socially, intellectually and spiritually, the requirements for a well ordered society change, hence the next Manifestation brings social and spiritual laws necessary for humanity at that stage of development. So, in fact, it does matter which one you follow in terms of humanity's progress.
Manifestations come to humanity at times when societies are at their nadir.
The longer the period that the Prophet is rejected, the longer the period of social and moral decline of that civilization. I would ask that you forgive his mumbling and allow me to clearly state the Baha'i position here for your consideration - which does differ from the mainstream Christian trinitarian view of God. Let me begin with something I think we can agree upon - God is completely beyond the understanding of mortal men. We are shut out from a complete comprehension of our Creator. But in His love for us, He has sent Prophets to guide us.
