Jesus taught that every part of the Old Testament is inspired and authoritative: the law, the writings, and the Psalms (Lk. 24:44). He taught the men spoken of in the books wrote them, that the Old Testament writers were inspired by God to write the Scriptures.. According to the Son of God, Moses wrote the books of the law (Lk. 24:44; Jn. 5:45-47); David wrote the Psalms bearing his name (Lk. 20:42); Daniel wrote the book bearing his name (Mt. 24:15).

The Bible is the written word inspired by God’s Spirit, moving men who worshipped God, were obedient to write. Written by over 36 authors on 3 different continents that differed in languages, backgrounds, and cultures. From various professions, as fisherman, to an educated doctor, from a shepherd to educated men in the finest schools of their time (Moses, Saul of Tarsus) They wrote in unity on the main topics.

Inspiration does not mean all the words or actions that are recorded in the Bible are inspired-- as if by God made them happen. For example it is recorded in Scripture Peter denied the Lord three times, but God did not inspire his actions or words of denial. Solomon as he was backslidden was musing and caught in worldly philosophy yet he knew the truth and struggled with it. In Ecclesiastes we see a contrast in his statements from his own human reasoning and the wisdom that was from God that was accurate knowledge.

If one does not accept the Old Testament then they cannot believe the words of Jesus, because he referred to it consistently during his ministry. The Apostle Paul wrote in 2 Tim. 3:16, “All scripture is given by inspiration of God…. Not just the red ink portions. We do not make our decision of acceptance by what we feel comfortable with. ALL of it is inspired. All of it may not be applicable to us but we are to recognize it is from God.

Jesus said, “The words that I speak unto you, they are spirit, and they are life.” Jesus quoted the Old Testament (Deut.8:3) in Matt 4:4, “It is written, 'Man shall not live by bread alone, but by every word that proceeds from the mouth of God.'“

Jesus taught that the Old Testament is perfect to the letter (Mt. 5:17-18). It cannot be broken (Jn. 10:35). It is authoritative to every detail. The Greek word translated “broken” in Jn. 10:35 is elsewhere translated “put off” (Acts 7:33) and “loose” (Jn. 11:44). No statement in the Bible can be put off or disregarded. All will be proven true. This is the doctrine of inerrancy and infallibility.

Jesus taught that the Old Testament characters, events, and miracles are true and historical. Some of the Old Testament people and events Christ referred to are as follows: the creation (Mk. 13:19), Adam and Eve (Mt. 19:4-6; Mk. 10:6-7), Cain and Abel (Mt. 23:35; Lk. 11:50-51), Noah and the flood (Mt. 24:37-39), Abraham (Jn. 8:39-40), the destruction of Sodom and Gomorrah (Lk. 17:28-29), Lot's wife turning to salt (Lk. 17:32), Moses and the burning bush (Mk. 12:26), Jonah and the whale (Mt. 12:39-41; Lk. 11:29-32), Nineveh repenting at Jonah's preaching (Lk. 11:32), The queen of Sheba visiting Solomon (Lk. 11:31). These are all literal events involving people.

The Old Testament is a book written in advance on the coming of Christ through the prophets and the writings. (Lk. 24:44). Christ is the central person in the Scripture (Lk. 24:46-47; John 5:39, 46; Acts 17:2-3) The New Testament was written within 20-30 years (except John’s epistles and Revelation) of the Jesus death and was written by eyewitness. They prove this by the statement, and authors themselves. There is internal evidence - Matthew refers to himself as a “tax collector” (Matthew 10:3); John refers to himself indirectly as “the disciple whom Jesus loved” and his rivalries with Peter (John 20:4, 21:20-22).  Luke in the second writing (Acts) alludes to the first epistle, his Gospel; Mark makes an reference to himself (Mark 14:51-52);

We are constantly affirmed of the witnesses (John 19:35, 2 Peter 1:16), places and events were historical and accepted by the contemporaries that could challenge it if not accurate.

Sir William Ramsay, one of the greatest archaeologists who ever lived wrote of Luke the author of the gospel and the book of Acts stating, “Luke is a historian of the first rank; not merely are his statements of fact trustworthy, this author should, be placed along with the very greatest of historians. Luke's history is unsurpassed in respect of its trustworthiness.”

Paul says in 1 Corinthians 15 to ask the eyewitnesses about the resurrection to validate what he is stating, since some of the 500 witnesses that saw him alive were still living when he wrote this.

The Bible is revealed truth from God which separates the Bible from any other book written in the history of the world.

The Bible is called “the word of truth (2 Tim 2:15), Daniel called it “the Scripture of Truth” (Dan.10:21), Prov.30:5: “Every word of God is pure.”

If one does not believe the word, called the Bible, then they cannot believe the one who is “the word” Jesus Christ, nor the one who inspired the word (the Holy Spirit, the Spirit of truth). Ones proof of orthodoxy is how they treat the word, because this will reflect on how they think of Jesus, the word made flesh.
