Not many believers may considered wise or powerful according to human standards, or may not being 'well born' or from "blue blood". In the Scriptures may be found many words also from foolish men. Many wrong actions of men are notated in the bible so that people can learn from them. Those foolish things of the world God chose in order that He might put to shame the wise, and the weak things of the world God chose in order that He might put to shame the strong, and the insignificant of the world.
Archaeology, in the last decades, may have uncovered a lot of biblical events and figures, but no archaeological confirmation is likely to ever deliver any kind of death blow to the side of disbelief.
