Many are the thoughts of the flesh

A little somethings extra is often I think just because many can think only of what they know, that that is al there is to know. So and so is so smart he knows everything. Everything is only what they know. We only know what God wants us to know. It is called an epiphany, a sudden awareness of a truth no one ever heard tell of before. It inspires a strong sudden unquestioned belief.

It is so compelling that it is not questioned. They will even risk their lives against the majority and are eventually often martyred as prophets. A prophet is someone who knows the future and predicts the future. Correctly it is later recognized. If they were not correct then they are a called false prophets, over taken by the seen world. My key word here is epiphany which first arose surrounded by the appearance of Jesus, known as the Christ.
