Well, there you go. There's something we can all evaluate and see if what Baha'u'llah has said and done fit with what the Bible says. So, let's go over it again. Where in the Bible does it foretell of Jesus? Then where does it tell of the coming of Muhammad? Then, after you have established that Jesus and Muhammad were both predicted in the Bible, then we can take a look at the verses you say it foretells of the Bab and Baha'u'llah.
For myself I’ve already satisfied myself of the truth of these Prophets through my own investigation which took years of reading, questions and reflection. That is up to each person to do his/her own research to discover the truth of these claims.
To go through them all or even just some of them would not be possible. Also, if it is your own search then only the effort you put into it will reap any gain. There are many sources you can research on the internet.
Various websites point to prophecies about Christ or Muhammad.
But for Baha’is they have known Baha’u’llah by His Self, Writings and Life. His works such as the Book of Certitude are worth reading. But I can only convince myself by doing my own research and only I can ultimately be satisfied that something is true.
The best I can do is suggest some resources that I think are worth studying but then it’s up to you if you want to investigate or not. You are the one that needs to look into the matter if it interests you. I had to do my own search too.
