Philosophersaid,
“That was a mistake on my part. I believe the Torah is divine even if I would not see any logical proofs of that.”
Exactly! You have already made up your mind about what you want to beleive and nothing can change that. Saying that and trying to
convince people that your beleif will lead them to a happier life may be succesfull.
Telling them that they should beleive in the Torah because it is the logical thing to do, and people who dont think it is logical only think so because they have already made up THEIR minds not to beleive while you yourself admit that you beleive JUST BECAUSE YOU DO is simply wrong and will come across as arrogant hypocritical and wrong to many people.
