How Do We Know the Bible Is True? What Peter Wants You to Understand About God’s Word
Fake news, hoaxes, and myths are nothing new. Nearly 2,000 years ago, the apostle Peter faced accusations that his message about Jesus was nothing more than a cleverly invented story. His response, found in 2 Peter 1:16-21, gives us one of the most important passages in the Bible about the Bible itself.
What Was Peter Being Accused Of?
False teachers in Peter’s day were telling people to ignore the apostles. They claimed the message about Jesus was just a myth, a word that carries the same meaning we think of today when we hear the word “mythology.”
Peter pushed back directly: “We did not follow cleverly devised tales when we made known to you the power and the coming of our Lord Jesus Christ, but we were eyewitnesses of His majesty.” – 2 Peter 1:16
The two things being called myths were the power of Jesus Christ and His return. Peter’s answer was clear: our faith is not built on fiction. It is built on evidence.
How Do We Know the Bible Is True?
1. Eyewitness Testimony
Peter points to a specific moment that he personally witnessed: the Transfiguration. Jesus took Peter, James, and John up a mountain where He was glorified before them, and the voice of God the Father spoke directly: “This is my beloved Son, with whom I am well pleased.” – 2 Peter 1:17
Peter says plainly, “We ourselves heard this declaration made from heaven when we were with Him on the mountain.” – 2 Peter 1:18
This was not secondhand information. Peter saw Jesus in His majesty and heard the Father’s voice with His own ears.
And Peter was not alone. Paul records in 1 Corinthians 15 that after the resurrection, Jesus appeared to Peter, then to the twelve, and then to more than 500 people at one time, most of whom were still alive when Paul wrote those words. People could go and ask them. The record was open to scrutiny, and no one successfully contradicted it.
2. The Miraculous Preservation of Scripture
Peter says simply, “We have this word.” That phrase carries enormous weight. Consider what this book actually is: 66 books, written by more than 40 different authors, on three different continents, over a period of 1,500 years, all telling one unified message.
History and archaeology continue to support the Bible’s reliability. Coins, pottery, towns, and people mentioned in Scripture have been confirmed through archaeological discovery. In 1947, Bedouin shepherds discovered the Dead Sea Scrolls in caves near Qumran. Among the 25,000 fragments recovered were manuscripts dating back to 200 BC, more than a thousand years older than the oldest texts previously available. When compared, the consistency was remarkable. The text had been faithfully preserved across centuries.
3. Prophetic Fulfillment
There are more than 3,300 prophecies about the life, death, and resurrection of Jesus Christ in the Old Testament, all fulfilled in precise detail. Peter calls attention to this when he says, “We have the prophetic word made more sure.” – 2 Peter 1:19
This connects directly to the Transfiguration. Moses represented the Law. Elijah represented the Prophets. When the Father spoke and they disappeared, the message was clear: the Law is completed and prophecy is fulfilled in Jesus alone.
After His resurrection, Jesus Himself confirmed this on the road to Emmaus: “Beginning with Moses and all the prophets, He explained to them the things written about Himself in all the Scriptures.” – Luke 24:27
All of it points to Him.
4. Its Illuminating Truth
Peter describes the Word of God as “a lamp shining in a dark place.” – 2 Peter 1:19
The world can be a very dark place. But as an old Jewish proverb says, even a little light dispels much darkness. John 1:5 says, “The light shines in the darkness, and the darkness cannot overcome it.”
The Word of God does not just inform. It exposes. It penetrates. It reveals things in us we did not even know were there. Hebrews describes it as sharper than a two-edged sword, discerning the thoughts and intentions of the heart. Many people have experienced this firsthand: reading Scripture at just the right moment and feeling the Spirit of God speak directly into their situation.
5. Its Transformational Power
Consider who Peter was when he wrote these words. He was the man who denied Jesus three times. He was the man Jesus once rebuked sharply. But something changed. Days after the resurrection, Peter stood up and preached the gospel, and 3,000 people were saved. He spent the rest of his life proclaiming Jesus and ultimately died as a martyr for His faith.
Peter says that when you place your faith in the Lord Jesus Christ, “the morning star rises in your hearts.” – 2 Peter 1:19. Something happens. A transformation takes place that is real, personal, and ultimately visible in a changed life.
Our faith is not based on secret knowledge or religious speculation. It is based on the truth of God and His Word, and the evidence of what that Word does in a human life.
Why Does It Matter That the Bible Is True?
Because a Day Is Coming
Peter urges his readers to pay attention to God’s Word “until the day dawns.” That phrase points to the Day of the Lord, the day when God is fully vindicated, when all that is wrong is made right, and when every person stands before a holy God. There will be no second chances after that day. The urgency of taking God’s Word seriously is tied directly to the reality of eternity.
Because It Is All About Jesus
From the very first verse of this passage, Peter anchors everything in “the power and the coming of our Lord Jesus Christ.” Jesus is the morning star. He is the fulfillment of prophecy. He is the true light. He is the one who transforms hearts. The entire Bible, from beginning to end, is introducing people to the Son of God. He is the focal point of Scripture and the focal point of history.
Because God Said It
Peter closes with this: “No prophecy was ever made by an act of human will, but men moved by the Spirit of God spoke.” – 2 Peter 1:21
Paul echoes this in 2 Timothy 3:16-17: “All Scripture is inspired by God, and profitable for teaching, for reproof, for correction, for training in righteousness, so that the man of God may be thoroughly equipped for every good work.”
The Bible is not simply the words of Peter or Paul or Moses. It is the Word of the Spirit of God, breathed into the lives of human writers. Their personalities and writing styles are present, but the words themselves are inspired by God. In the same way that Jesus is both fully human and fully divine, this book carries both a human and a divine nature.
It matters because God said it. That alone is reason enough to take it seriously.
Life Application
This week, treat the Bible as what it actually is: the living Word of God, not just a religious book or a collection of good advice. Set aside time each day to read it slowly and prayerfully, asking the Holy Spirit to illuminate what you are reading and to reveal what He wants to say to you personally.
Ask yourself these questions as you reflect on this message:
- When was the last time I let the Word of God genuinely challenge or change something in my life, rather than just reading it out of habit?
- Do I treat the Bible as God’s authoritative Word, or do I pick and choose what I find convenient to believe?
- If someone asked me why I trust the Bible, could I give them a thoughtful answer based on evidence and personal experience?
- Is there an area of my life where I know what God’s Word says, but I have not yet submitted to it?
The Word of God is a lamp in a dark place. It is preserved across centuries, confirmed by hundreds of eyewitnesses, fulfilled in thousands of prophecies, and proven in transformed lives. It is true because God said it, and it is all pointing to Jesus. Pay attention to it. Your eternity depends on it.
