Logical reasoning:

• The Word of God as given to us in the Bible is a product of two free agents, human and divine.
• Through (fallible) human authors, God manifested the infallible and errorless writings, which convey His messages.
• Why did God choose to have humans write the Bible? Although God is sovereign and can do anything by Himself,
  He chooses to have humans interact in His plan. This is one of the biggest differences between our religion and
  other religions; with God reaching down to man, instead of man reaching up to Him.
• The Bible was written by 40 men, from geographically different areas, over a period of 1,600 years, yet
   prophesies agree hair rising accurate.
• Archaeological findings support the accuracy of the Bible - from ancient ruins to cities mentioned in Scripture. Thus,
  the Bible cannot be a “book of stories”, as nobody can reason the archaeological finding away.

Scriptural proof:

• The entire Bible is inspired by God, not just partially. (2 Tim 3:16).
• Since God is truth (John 3:33, Rom 3:4), then what is breathed out by God must also be true (John 17:17)
  and infallible.
• The process of inspiration is described in 2 Peter 1:21 – for prophecy never came by the will of man, but holy men
  of God spoke as they were moved by the YHWH’s Spirit.
• Examples of proof for the inspiration of the Bible is the fulfillment of the prophecies, particularly those relating to
  Y’shua – His birth- Isaiah 7:14, Micah 5:2; His crucifixion- Psalm 22:16-17, Isaiah 53:12; and His resurrection
  Psalm 16:10, 22:22.
• The apostles also attested the inspiration of the Scripture, in both the Old Covenant (Rom 3:2) and the Messianic
  Writings (2 Peter 3:15,16). Moreover, they proclaimed their own writings as God’s words (1 Cor 14:37), and their
  messages also as God’s words (Gal 1:12; 1 Thes 2:13).
• Y’shua never used Old Covenant events as if they were myths, legends or stories. On the contrary, their
  authenticity was essential to the point He was making. If Adam didn't really exist, then Y’shua's teaching on marriage
  falls to the ground (Mat 19:4-6). If David didn't really eat the showbread, then Y’shua's defence of His own similar
  action is left limping (Mat 12:1-4). If Jonah didn't really preach and Ninevah really repent, then Y’shua looks like a
  fool usingthis as an illustration of His own coming (Mat 12:41). Those who have a low view of the Old Covenant and
  the Messianic Writings will then make the Bible and Y’shua look naive.
• This means that Y’shua’s strongest statement about the complete trustworthiness of the Bible is then in John 10:35.
  In a discussion over His divinity He cited Psalm 82:6 and then appended the fateful words, "The Scripture cannot be
  broken." Since Scripture cannot be broken, an appeal to all Scripture is final; it cannot be challenged or disproved
  or denied.

Undeniable facts:

• There are 324 Messianic Prophecies (about Messiah Y'shua) in the Old Covenant. 65 on Y'shua's First Coming
  (His birth, life, death, and resurrection) and 259 on His Second Coming.
• The First Coming of Y'shua already happed and all 65 Prophecies were fulfilled with unprecedented accuracy …
  the rest on His Second Coming will(/are) also be literally fulfilled.
• No other religion in the world can claim this factual record of accurate fulfilled Prophecies.
• The Bible, then, is our authority precisely because it is not the word of man but of God, the Completely dependable
  Word of God, the Word of Truth (John 17:17). Anyone who says "Y’shua is Lord" and yet belittles the Word of God
  is inconsistent and hypocritical. We can demonstrate our submission to Y’shua's Lordship only by our absolute,
  unconditional surrender to the teachings of His Word.
