Christianity believes and teaches that the Bible alone is the revealed Word of God. Even though it was written by men, Christianity makes the claim that the ultimate author was God. This claim was not invented by Christian believers, but the Bible itself makes this claim as to being true.
“The grass withers and the flowers fall, but the word of our God stands forever.” (Isaiah 40:8)
“All Scripture is God-breathed and is useful for teaching, rebuking, correction and training in righteousness, so that the man of God may be thoroughly equipped for every good work.” (2 Timothy 2:16-17)
“For prophecy never had its origin in the will of man, but men spoke from God as they were carried along by the Holy Spirit.” (2 Peter 1:21)
Over 2,000 times in the Old Testament alone there are phrases such as “And God spoke to Moses,” “the word of the Lord came unto Jonah,” and “God said.” The Bible claims itself to be a record of the words and deeds of God – in essence His Story of the world. Finally, the Bible also views itself as God’s Message to the people so that they may be saved from their sins.
However, the mere fact that the Bible claims to be the Word of God does not prove that it is true, for there are other books that make similar claims. The key difference is that the Bible contains very strong evidence as being the actual Word of God. It is as if God is speaking directly to us. That is the authority that comes with the Bible.
There is also another significant reason that the Bible is different from other books. Although this book was composed by men, the unity of all its words show it was put together miraculously by the hands of God. The Bible was written over a period of about 1,500 years by more than forty different human authors covering many controversial subjects. Yet, there is an amazing unity to the Bible. From beginning to end, there is the unfolding story of God’s plan of salvation for mankind. This salvation is through the person of Jesus Christ (John 14:6) and Jesus Himself testified that He was the theme of the entire Bible (John 5:39, Luke 24:27).
The entire Bible is a unity with each part needing the others to be complete. There is complete harmony, which cannot be explained by coincidence or collusion. The unity of the Bible is a strong argument in favor of its divine inspiration. There are other reasons which could be explained in greater detail such as the testimony of the early Church, the witness of history and archaeology, and the evidence of changed lives throughout the centuries, to name but a few.
The bottom line is that the Bible is special. It is unique. No other book has any such credentials. No other book even comes close.
