What proof do we have for the inspiration of the Bible?

TL;DR:

Several lines of evidence establish that the Bible is God’s inspired Word. Inspiration is affirmed by fulfilled prophecy, biblical unity, historical and archaeological findings, and confirmation in the spirit of a believer.

what does the bible say?

From the reliability of the biblical witnesses, the factuality of archaeological finds, and the unity of the historical narrative we can readily see the inspiration of the Bible. The word “inspiration” simply means “God-breathed," or "spoken by God." It is not the same as when a poet or a songwriter claims to be inspired. Rather, God divinely influenced the human authors of the Scriptures in such a way that what they wrote was the very Word of God. The Bible declares it is inspired (2 Timothy 3:16-17). There are several lines of evidence that support the inspiration of the Bible. First is the proof of spiritual intimacy. The Lord is near to all who call on him in truth (Psalm 145:18). Draw near to God through faith in Christ who alone gives us access to God (Hebrews 7:25; Philippians 3:9). Without faith it is impossible to please God (Hebrews 11:6). The more time we spend in God's Word, the more confirmation we receive that the Bible is truly the inspired Word of God.

from the old testament

"The sum of your word is truth, and every one of your righteous rules endures forever" (Psalm 119:160). The result of divine inspiration is that the Bible is the very Word of God.
The phrase "Thus says the LORD" is a significant declaration in the Old Testament, occurring hundreds of times (from Exodus 4:22 to Malachi 1:4). It emphasizes the authority and truthfulness of God's Word.

from the new testament

"For he (Apollos) powerfully refuted the Jews in public, showing by the Scriptures that the Christ was Jesus" (Acts 18:28). Using Messianic prophecies, Apollos demonstrated to Jews that Jesus is the Messiah.
Paul says he did not use words based on human wisdom. Instead, he spoke and wrote words given to him by the Holy Spirit (1 Corinthians 2:13).
Paul also said the commands he wrote were of the Lord (1 Corinthians 14:37).
The Thessalonians accepted the gospel not as a human message but as the true word of God (1 Thessalonians 2:13).
"All Scripture is breathed out by God and profitable for teaching, for reproof, for correction, and for training in righteousness, that the man of God may be complete, equipped for every good work" (2 Timothy 3:16-17). Scripture itself declares it is inspired (God-breathed).
The early church regarded prophecy as inspired by the Holy Spirit (2 Peter 1:20-21), and Peter considered Paul's writings as inspired Scripture (2 Peter 3:15-16).

implications for today

The testimony of reliable witnesses—particularly Jesus, but also Moses, Joshua, David, Daniel, and Nehemiah in the Old Testament, and John and Paul in the New Testament—affirms the authority and verbal inspiration of the Holy Scriptures. Fulfilled prophecy is also clear evidence the Bible is inspired by God. The early church used fulfilled prophecies in the life of Jesus to prove to Jews that Jesus was the Christ (Acts 18:28). The Old Testament contains more than 300 prophecies concerning Jesus Christ’s first coming. There is no doubt that these are prophecies from God because of manuscripts dated from before the birth of Christ.

The unity of the Bible is likewise proof of its inspiration. It was written by about 40 authors over an approximately 1,500-year period in three languages on three continents. Its authors ranged from kings to shepherds and scholars to fishermen, yet it provides a consistent history of redemption. Many historical and archaeological findings support the accuracy and reliability of Scripture, offering additional proof of the inspiration of the Bible. From the kings of Israel to the kingdoms of Babylon and Persia, the Bible speaks accurately on history. Considering the evidence, it is plain that the Bible is from God.

Knowing that the Bible is inspired by God, we are called not to just admire its wisdom but to respond by reading it and heeding it—putting it into action. God has revealed Himself through His Word for us to know Him and to guide our lives, not simply to inform our minds. Listening and heeding God’s Word means giving it priority over our own opinions, culture, and feelings. Obeying it means living out what we hear—surrendering sin, walking in love, and faithfully following Jesus even when it’s uncomfortable. When we submit to God’s Word, we experience His presence, power, and peace in real and personal ways. Our lives are a testimony that God is not only the One who inspired Scripture but the Lord of all our lives.
