Voddie Baucham is a Christian apologist who makes it quite clear his answer to the question “Why I choose to believe the Bible.”

Here it is:
“I choose to believe the Bible because it’s a reliable collection of historical documents written down by eyewitnesses during the lifetime of other eyewitnesses.  They recorded supernatural events that took place in fulfillment of specific prophecies and claimed that their writings are Divine rather than human in origin.”

It is worth the time to hear him unpack the reasoning behind his well thought out and straight to the point explanation of why the Bible is believable compared to any other scriptures on earth.
