God is so incredibly magnificent that words fail to describe Him. We sing a song sometimes called " O For A Thousand Tongues ". And yet, even were we all to have a 1,000 tongues to sing our great Redeemer's praise, we would fall short of the praise He is due.
I believe it was R. C. Sproul who said there was not one maverick molecule in the universe. A simple perusal of the Bible demonstrates this and that history is under divine control and following a divine timetable and fulfilling divine purposes. And to view history as a series of random events is to miss the point of creation in the first place.
I am always intrigued, though, as you seem to be, how individuals come to believe as they do.
