I could be wrong in this. But wasn't his writings only for himself and was published only later. How many people really referred to his writings? When was printing press invented? How popular was it compared to Bible? Was it possible for people to consume his writings in multimedia formats like video, audio? Were there meme-pages on tiktoks which contextualized his writings in different day-to-day scenarios so that the importance of his general ideas were imprinted on their minds? Did he have debate with others to defend his ideas watched by many, how would he respond to those counter-arguments? Would your mind change considering if his responses weren't that strong or on filmsy grounds?
