Why is Scripture necessary? Couldn’t God reveal Himself other ways?
Question 1034
If God is all-powerful, couldn’t He reveal Himself without a book? Couldn’t He speak directly to each person, write His truth on the sky, or simply implant knowledge in our minds? Why do we need Scripture at all? This question touches on what theologians call the “necessity of Scripture”—and the answer reveals something beautiful about both God and ourselves.
God Does Reveal Himself Other Ways
Let’s start by acknowledging what Scripture itself affirms: God does reveal Himself through means other than the Bible. Theologians distinguish between “general revelation” and “special revelation.”
General revelation is what God shows about Himself through creation, conscience, and providence. Psalm 19:1-4 declares, “The heavens declare the glory of God, and the sky above proclaims his handiwork. Day to day pours out speech, and night to night reveals knowledge. There is no speech, nor are there words, whose voice is not heard. Their voice goes out through all the earth, and their words to the end of the world.”
Paul picks up this theme in Romans 1:19-20: “For what can be known about God is plain to them, because God has shown it to them. For his invisible attributes, namely, his eternal power and divine nature, have been clearly perceived, ever since the creation of the world, in the things that have been made. So they are without excuse.”
Creation reveals that God exists, that He is powerful, that He is wise, that He is eternal. The human conscience, written on every heart (Romans 2:14-15), reveals that God is moral and that we are accountable. Providence—the way God orders history—reveals His sovereignty and care.
So yes, God could and does reveal Himself apart from Scripture. The question is: what kind of revelation do we need?
The Limits of General Revelation
Here’s the problem. General revelation tells us that God exists and that we’re accountable to Him. But it doesn’t tell us who this God is in His fullness, what He requires of us specifically, or how we can be reconciled to Him when we’ve fallen short.
Look at the world around us. People everywhere recognise that there’s something greater than themselves. Every culture has some form of religion or spirituality. But look at the diversity and confusion of those religions! Creation reveals a Creator, but it doesn’t reveal whether there’s one God or many, whether He’s personal or impersonal, whether He loves us or is indifferent to us. General revelation gives us enough to know we’re in trouble; it doesn’t give us enough to know how to get out of trouble.
Romans 1 goes on to describe what happens when people have only general revelation and suppress even that: they become futile in their thinking, exchange the glory of God for idols, and spiral into moral confusion and judgment. General revelation makes us accountable; it doesn’t save us.
This is why we need special revelation—God speaking specific words to specific people, revealing specific truths that cannot be known any other way. And Scripture is the written record of that special revelation, preserved for all generations.
Why Written Revelation?
But why a book? Couldn’t God just speak to each person directly?
Consider the practical problems with unwritten, individualised revelation. How would you know if what you heard was really from God? People throughout history have claimed divine messages, and they contradict each other constantly. Without a fixed, objective standard, there’s no way to test these claims. Written Scripture provides exactly that standard—an unchanging benchmark against which all claimed revelations can be measured.
Moreover, human memory is fallible. Even if God spoke directly to you, you might misremember what He said. You certainly couldn’t pass it on accurately to the next generation, and the next after that. Written Scripture preserves God’s words exactly, across thousands of years and countless translations, so that what Moses wrote, what David sang, what Paul taught is still available to us today.
Jesus Himself valued written Scripture. When tempted by Satan, He responded three times with “It is written” (Matthew 4:4, 7, 10). When teaching, He constantly appealed to what was written. When confronting the Sadducees’ error, He said, “You are wrong, because you know neither the Scriptures nor the power of God” (Matthew 22:29). If anyone could have bypassed written Scripture in favour of direct divine communication, it was Jesus—He is God! Yet He honoured and used the written Word.
The apostles continued this pattern. Paul wrote letters to churches precisely because he couldn’t be with them in person, and those letters carried apostolic authority even in his absence. Peter put his teaching in written form “so that after my departure you may be able at any time to recall these things” (2 Peter 1:15). Written Scripture transcends the limitations of time and space that constrain oral communication.
What Scripture Reveals That Nothing Else Can
Scripture reveals truths that are simply unavailable through other means.
The Gospel. How would you know that God sent His Son to die for sinners if Scripture didn’t tell you? Creation might hint at God’s power and wisdom, but it doesn’t proclaim the cross. Conscience might convict you of sin, but it doesn’t announce forgiveness. The Gospel—the good news that Jesus died for our sins, was buried, and rose again (1 Corinthians 15:3-4)—is revealed in Scripture and nowhere else.
God’s character in detail. Scripture reveals not just that God exists but who He is—His holiness, His justice, His mercy, His faithfulness, His triune nature as Father, Son, and Holy Spirit. Where else would we learn that God is “merciful and gracious, slow to anger, and abounding in steadfast love and faithfulness” (Exodus 34:6)?
God’s plan for history. Scripture reveals where we came from (creation), what went wrong (the fall), how God is putting it right (redemption), and where everything is heading (consummation). Without Scripture, we’d be lost in the middle of a story with no knowledge of the beginning or the end.
God’s will for our lives. How should we live? What does God require of us? Scripture tells us: “He has told you, O man, what is good; and what does the LORD require of you but to do justice, and to love kindness, and to walk humbly with your God?” (Micah 6:8). Conscience gives us a general sense of right and wrong, but Scripture gives us specific guidance for honouring God in every area of life.
Salvation. Most importantly, Scripture tells us how to be saved. “Faith comes from hearing, and hearing through the word of Christ” (Romans 10:17). Without the preaching of the Gospel—which depends on the scriptural revelation of that Gospel—no one would be saved. Scripture is necessary because salvation is necessary, and Scripture is the means God has chosen to make salvation known.
The Necessity of Scripture for the Church
Beyond individual salvation, Scripture is necessary for the life of the church.
How would we know how to worship if not for Scripture? Left to ourselves, we’d invent all sorts of worship—and history shows that people do exactly that, often with disastrous results. Scripture regulates our worship, telling us what pleases God and what doesn’t.
How would we recognise true teaching from false? Without an authoritative standard, any persuasive speaker could lead us astray. But with Scripture, we can test everything (1 Thessalonians 5:21) and hold fast to what is good.
How would we maintain unity across time and space? The church spans two thousand years and every continent. What holds it together? A shared Scripture. Christians in first-century Corinth and twenty-first-century Korea read the same Bible and worship the same God revealed in its pages.
A Gift, Not a Burden
Some people treat the necessity of Scripture as a problem—as if God is limited because He chose to reveal Himself through a book. But that gets it backwards. Scripture is not a limitation; it’s a gift.
It’s a gift of clarity—God has spoken plainly enough that ordinary people can understand the way of salvation. It’s a gift of accessibility—you don’t need a priest or a mystical experience to encounter God; you can open His Word and hear from Him. It’s a gift of stability—God’s truth doesn’t shift with cultural winds or personal feelings; it remains constant across the ages.
The alternative—trying to know God through general revelation alone, or through subjective experiences, or through human traditions—leaves us confused, uncertain, and ultimately lost. Scripture cuts through all that and gives us “a lamp to my feet and a light to my path” (Psalm 119:105).
Conclusion
Could God reveal Himself other ways? He does—through creation, through conscience, through providence. But these forms of revelation, while real, are insufficient to save us. They tell us God exists; they don’t tell us how to know Him. They reveal His power; they don’t reveal His mercy. They convict us of sin; they don’t proclaim forgiveness. For that, we need Scripture—God’s own words, preserved in writing, revealing His character, His plan, His will, and above all, His Son. Scripture is necessary because we are sinners who need to know the way of salvation, and Scripture is where God has made that way known.
