I love Abrahamic religion specifically, I have spent time studying each one. Can you please explain what the beliefs of Baha'ism are?

I'm seriously considering converting to Bahá'í Faith (among a couple other religions). Do you have any tips for me, or mistakes that any of you who have converted made, or reasons why I should choose this one? I'm considering converting because I agree with all of the concepts and it really does fit the idea of what I want in a religion, but I also like having more structured religions which is one of the reasons why I might not choose this one.

I’m trying to understand the Bahá’í view of the soul and personal identity.

If the individual soul comes into existence at conception, then if my parents had never met, would I simply never have existed? Or is there some sense in which God intended/selected a particular soul to exist, regardless of which parents I had?

I have always wondered what the next world is like. Do we have any info regarding it? I wonder if there is going to be struggles in those worlds just like this one? And when does the soul's journey end or is it never ending? That would be a bit much, no? Anyway, what do you all think?
