A college professor under whom I once studied spoke of a theologian with whom he disagreed, saying, "It isn't that he isn't a brilliant man‑‑it's just that he knows so many things that aren't true."  If truth is subjective, if it is only a matter of personal opinion, then good men can disagree and both be right.  But if historical data is supported by corroborating evidence, and if the character of the men who wrote it is supportive, then ultimately, we have to come face to face with facts. That is the situation when it comes to accepting or rejecting the credibility of the Bible.
