Pascal was a genius before he was a saint (he has still not been canonised). Geometry was his speciality, but from a very young age he had such knowledge and intuition that many today recognise his name as a computer language. He was also a sick man. And a mystic. The film plays with an extraordinary ellipsis, from conversion directly to death, without ignoring the Pascal who kept the description of his visions sewn into the lining of his coat, or who made the existence of God a kind of game theory, a bet that no one can guarantee they have won or lost.
