I had this convo with one of my buddies the other week. he even knew that the bible was a hodgepodge compilation of stories compiled over a long period of time by many authors. it's quite the contradiction.
ultimately I think it mainly has to do with how a persons belief system shapes their own individual view of reality combined with genetic and environmental factors.
Consider the fact that the Bible is comprised of 66 Books written over a period of about 1,500 years by over 40 authors from all walks of life, with different kinds of personalities, and in all sorts of situations. It was written in three languages on three continents, and it covers hundreds of controversial subjects. Yet, it fits together into one cohesive story with an appropriate beginning, a logical ending, a central character, and a consistent theme.
How does one begin to explain such historical, structural, prophetic, doctrinal, and spiritual congruency (harmony) apart from the fact that its real author was Divine?
Also remember that these men were not writing about something as simple as an action adventure hero. They were dealing with controversial subjects, such as the meaning of life, the nature of God, angelic beings, and God's plan of redemption. These are matters on which it is generally
not humanly possible to check the facts firsthand or to even fully understand, so as to write in complete agreement with all other biblical authors past and future. Yet, all 40 did write in unity and with authority. Either they were inspired, or they cheated to produce congruency.
The fact that the Bible has unity despite obvious differences in content, style, and perspective is a powerful witness to the independence of each author.
The Bible portrays an incredibly consistent picture of the Messiah throughout all 66 of its Books.
One should expect chaos from 40 different authors (most didn't know each other) on 3 different continents written over a period of 1500 years. The logical explanation is, "the bible is Gods Word".
