How Do We Know The Bible Is God’s Word?
The Bible claims for itself VERBAL INSPIRATION.
This is the doctrine that God chose to Breathe His words through His prophets, that these prophets SPOKE God’s words, and that these words were later reduced to the writings that we know today as the Holy Scriptures (2 Tim. 3:16-17; 2 Pet 1:20-21; 2 Sam 23:2; Jer. 1:9; Luke 1:70; Jer 36).
Christians generally believe this doctrine by faith alone, which is good, but can it be proven?
Yes, it can. Any reasonable person would accept the following arguments as legitimate proof for the inspiration of Scripture.
The Bible Is A Negative Book
Why would man write a book to condemn his own race?
From cover to cover the Bible is NEGATIVE toward man. It utterly condemns man (Psa 39:5; Isa 64:6; Rom 3:10-18; John 3:18; Jer 17:9; Psa 51:5).
The Bible Is An Authoritative Book
Most ancient writings do not even profess inspiration, but the Bible professes not only to be inspired, but to be the ONLY inspired writing (Isa. 8:20). The central character of the Bible, the Lord Jesus Christ, professes to be the ONLY way to Heaven. Unlike the ancient philosophers, the men of the Bible are men who speak with great power, certainty, and authority.
The Bible Is An Infallible Book
Although many have tried, and are still trying, no one has ever proven that there are mistakes in the Bible (KJV). All apparent errors and contradictions can be explained Scripture with Scripture and by closely studying the context.
The Bible Is An Old Book
It’s the oldest REAL book in the world. It was the first book printed on a press.
The Bible Is A Prophetic Book
While other ancient writings do not even attempt prophecy, the Bible attempts it and fulfills it! One only has to consider a few Old Testament prophecies about the life of Christ to see this (Num. 24:17-19; Gen. 49:10; Mic. 5:2; Isa. 7:14; Dan. 9:25; Hos. 11:1; Isa. 53; Zec. 9:9; Psa. 69:21; Psa. 34:20; Psa. 16:10; Psa. 41:9; Zec 11:12; Psa. 35:11; Psa. 22).
The Bible Is A Unified Book
The sixty-six books of the Bible were written by some thirty-five or forty different authors, on three continents, over a period of 1,800 years. These men came from all walks of life, differing greatly from one another, but their writings never contradict. These books COMPLIMENT one another. Such an accomplishment would be impossible if the Holy Spirit were not the Divine Author.
The Bible Is An Interesting Book
Unlike other books, the Bible is read by all classes of people. A small remnant of people from all walks of life share an interest in the Bible (educated, non-educated, old, young, male, female, black, white, rich, poor, etc.)
The Bible Is A Best-Selling Book
Over 800,000,000 copies sold since 1611. Over 2,000,000 per year, and over 5000 per day. This is a very conservative estimate, and it doesn’t include those translated for missionary work.
The Bible Is A Blessed Book
It has changed more lives than any other book in world history. Eighty-eight percent of the colleges in America were founded for the purpose of teaching God’s word and training missionaries. Many literary countries are the product of Bible-believing Christianity. Nations and individuals always prosper when Bible principles are followed.
The Bible Is A Preserved Book
If the Bible is only a man-written book, then why does it still exist?
Satan has fought endlessly to rid the world of the Bible, yet it still exists today. Everything that man accomplishes eventually falls apart (wonders of the world, educational system, governments, etc.), but the Bible lives on.
Psalm 12:6-7 NKJV
The words of the LORD are pure words, Like silver tried in a furnace of earth, Purified seven times.  You shall keep them, O LORD, You shall preserve them from this generation forever.
Matthew 24:35 NKJV
Heaven and earth will pass away, but My words will by no means pass away.
