There are both internal and external evidences that the Bible is truly God’s Word. The internal evidences are those things within the Bible that testify of its divine origin. One of the first internal evidences that the Bible is truly God’s Word is seen in its unity. Even though it is really sixty-six individual books, written on three continents, in three different languages, over a period of approximately 1500 years, by more than 40 authors who came from many walks of life, the Bible remains one unified book from beginning to end without contradiction. This unity is unique from all other books and is evidence of the divine origin of the words which God moved men to record.
Another of the internal evidences that indicates the Bible is truly God’s Word is the prophecies contained within its pages. The Bible contains hundreds of detailed prophecies relating to the future of individual nations including Israel, certain cities, and mankind. Other prophecies concern the coming of One who would be the Messiah, the Savior of all who would believe in Him. Unlike the prophecies found in other religious books or those by men such as Nostradamus, biblical prophecies are extremely detailed. There are over three hundred prophecies concerning Jesus Christ in the Old Testament. Not only was it foretold where He would be born and His lineage, but also how He would die and that He would rise again. There simply is no logical way to explain the fulfilled prophecies in the Bible other than by divine origin. There is no other religious book with the extent or type of predictive prophecy that the Bible contains.
A third internal evidence of the divine origin of the Bible is its unique authority and power. While this evidence is more subjective than the first two, it is no less a powerful testimony of the divine origin of the Bible. The Bible’s authority is unlike any other book ever written. This authority and power are best seen in the way countless lives have been transformed by the supernatural power of God’s Word. Drug addicts have been cured by it, homosexuals set free by it, derelicts and deadbeats transformed by it, hardened criminals reformed by it, sinners rebuked by it, and hate turned to love by it. The Bible does possess a dynamic and transforming power that is only possible because it is truly God’s Word.
There are also external evidences that indicate the Bible is truly the Word of God. One is the historicity of the Bible. Because the Bible details historical events, its truthfulness and accuracy are subject to verification like any other historical document. Through both archaeological evidences and other writings, the historical accounts of the Bible have been proven time and time again to be accurate and true. In fact, all the archaeological and manuscript evidence supporting the Bible makes it the best-documented book from the ancient world. The fact that the Bible accurately and truthfully records historically verifiable events is a great indication of its truthfulness when dealing with religious subjects and doctrines and helps substantiate its claim to be the very Word of God.
Another external evidence that the Bible is truly God’s Word is the integrity of its human authors. As mentioned earlier, God used men from many walks of life to record His words. In studying the lives of these men, we find them to be honest and sincere. The fact that they were willing to die often excruciating deaths for what they believed testifies that these ordinary yet honest men truly believed God had spoken to them. The men who wrote the New Testament and many hundreds of other believers (1 Corinthians 15:6) knew the truth of their message because they had seen and spent time with Jesus Christ after He had risen from the dead. Seeing the risen Christ had a tremendous impact on them. They went from hiding in fear to being willing to die for the message God had revealed to them. Their lives and deaths testify to the fact that the Bible truly is God’s Word.
A final external evidence that the Bible is truly God’s Word is the indestructibility of the Bible. Because of its importance and its claim to be the very Word of God, the Bible has suffered more vicious attacks and attempts to destroy it than any other book in history. From early Roman Emperors like Diocletian, through communist dictators and on to modern-day atheists and agnostics, the Bible has withstood and outlasted all of its attackers and is still today the most widely published book in the world.
Throughout time, skeptics have regarded the Bible as mythological, but archeology has confirmed it as historical. Opponents have attacked its teaching as primitive and outdated, but its moral and legal concepts and teachings have had a positive influence on societies and cultures throughout the world. It continues to be attacked by pseudo-science, psychology, and political movements, yet it remains just as true and relevant today as it was when it was first written. It is a book that has transformed countless lives and cultures throughout the last 2000 years. No matter how its opponents try to attack, destroy, or discredit it, the Bible remains; its veracity and impact on lives is unmistakable. The accuracy which has been preserved despite every attempt to corrupt, attack, or destroy it is clear testimony to the fact that the Bible is truly God’s Word and is supernaturally protected by Him. It should not surprise us that, no matter how the Bible is attacked, it always comes out unchanged and unscathed. After all, Jesus said, “Heaven and earth will pass away, but my words will never pass away” (Mark 13:31). After looking at the evidence, one can say without a doubt that, yes, the Bible is truly God’s Word
