Hi Bahman. I’m not saying a world without religious doubt is impossible. If God wanted to created such a world, he could. What I am saying, is that it is impossible for you or me to exist in such a world. As the particular, unique individuals which we are, our existence depends on the life history of our parents, grandparents and ancestors. If their life histories were too different, we would never have been born. And world history contributes heavily to life history, so if world history was sufficiently different, we would never have existed.
In my case, my mother was born in the UK, and her family moved to Australia in the early 1950s, when she was a young child. Their decision to leave the UK was heavily influenced by the circumstances of post-war Britain. Their decision to go to Australia, instead of the US or Canada, was due to my great aunt having already moved to Australia - she had met an Australian soldier stationed in the UK during the Second World War, married him, and then when the war finished moved to Australia to be with him. So, in a world in which World War II never happened, it seems rather unlikely that my maternal grandparents would have moved to Australia. My great uncle (by marriage) would probably have never enlisted, probably never been deployed to the UK, never met my great aunt, she would have never having ended up moving to Australia, and then my grandparents would have had no reason to choose Australia over the US or Canada - they probably would have chosen the US or Canada instead, because my grandfather partially grew up in the US, and they had relatives in both countries. Furthermore, their decision to leave the UK was due to the post-war economic and political situation - if WW2 had never happened, that economic and political situation would have never happened either, and they might well have stayed in the UK. And, if my mother never moved to Australia in the 1950s, if her family had stayed in the UK or gone to the US or Canada instead, she would have almost certainly never met my father as a university student in the 1970s - my father’s ancestors all came to Australia in the 19th century. So it is pretty clear to me, than in a world in which WW2 never happened, I would never have been born - and my son would not have either.
Now, I don’t know anything about your personal family history, but I’m pretty sure it depends (whether you know it or not) on major historical events like WW2 or other wars occurring. So, even without knowing anything about your own family history, I can say that if world history was significantly different, it is very unlikely you would have ever been born.
And, as I’ve argued, in a world in which God spoke to us all face to face, in such a way that no one could plausibly doubt his existence and commandments, events like WW2, and just about all other wars, would probably have never happened. International disputes would be really easy to resolve - just ask God, and he will answer, and then everyone will do what he says. Horrors like the Nazi war crimes, the Holocaust, would not have occurred - if Hitler spoke to God every day, and God said to him “I know what you are thinking, and if you do that you are going to hell”, do you think Hitler would have still done the horrible things he did?
So, a world in which God spoke to us all face to face, would be a world in which you or I were never born, nor anyone else whom we know. When we complain to God, that he has made a world in which religious doubt exists, we are complaining that he has made a world in which we exist. Now, self-love is the sort of thing which many people take too far, into sinful pride and selfishness, but I don’t think a moderate quantity of it is a bad thing; and if you have even the smallest quantity of self-love, how could you complain to God about your own existence? Or, if you don’t have any self-love at all, or if your life is so horrible you would have rather never been born (Job 3:3), do you have love for family and friends? Do you have any children? If I was to say to God “why did you create me?!”, I’d be saying to him “why did you create my son?!” (no me = no son). Given how much I love my son, I cannot say that.
