Literalism: Isn't the Bible historically unreliable and regressive?

Some people claim that they can't trust in the Bible because it is historically unreliable and culturally regressive. But do we have cultural blinders on? Dr. Keller discusses solid reasons that we can trust the Bible historically, culturally, and personally. This sermon was preached by Rev. Timothy Keller at Redeemer Presbyterian Church on November 5, 2006. Series "The Trouble with Christianity: Why it's so Hard to Believe it". Scripture: Luke 1:1-4; 24:13-32
