Authority of the Bible
"One of the strongest evidences that the Bible is inspired by God is its predictive prophecy. Unlike any other book, the Bible offers a multitude of specific predictions—some hundreds of years in advance—that have been literally fulfilled or else point to a definite future time when they will come true. In his comprehensive catalogue of prophecies, Encyclopedia of Biblical Prophecies, J. Barton Payne lists 1817 predictions in the Bible, 1239 in the Old Testament and 578 in the New Testament (674-75)" (Baker Encyclopedia of Christian Apologetics, Norman L. Geisler, p.609, Baker Books 2000, Grand Rapids, MI).
Because the Bible contains such infallible predictions, of which none to date have failed, then they are proof of the Bible’s divine origin.
Therefore, I think the key issue here is going to ultimately be: what is your final ultimate authority on all matters. The Bible, which is the Word of God, is the final authority on any matter that I consider, it is infallible, it is complete, it is inspired, it is proven, and it is consistent. You can not say that about any other authority in the universe. Therefore, I evaluate, weigh, and address all issues with the Word of God.
Based upon this authority, I believe that all men should be ready and willing to change whatever belief, desire, ceremony, or tradition; and toss out of their life, any teachings, teachers, religion, or religious leaders that go contrary to the Word of God.
