Why Is Scripture Necessary? Could Not God Reveal Himself Other Ways?

Question 1034.

Special revelation is not God’s only way of making Himself known, but it is His only sufficient way of making Himself known for salvation, and that distinction answers most of what lies behind this question. God has genuinely revealed something of Himself through creation, through conscience, and through the ordinary unfolding of history. None of that, however wonderful, tells anyone how to be right with Him. For that, something more is required, and Scripture is where that something more has been given.

General Revelation Is Real but Limited

Romans 1:20 states that God’s invisible attributes, His eternal power and divine nature, have been clearly perceived in the things that have been made, so that people are without excuse. Romans 2:14 to 15 adds that the work of the law is written on the human heart. This is general revelation: universal, genuine, and sufficient to render every person accountable before God. Anyone who has stood beneath a clear night sky or felt the unmistakable weight of a guilty conscience has brushed up against it, whether they recognised it as such or not.

But general revelation was never designed to save. It establishes accountability; it does not establish a remedy. It tells a person that God exists and that they have fallen short of Him. It does not tell them how the gap between a holy God and a guilty conscience can be closed. For that, something else has to enter the conversation.

Why Special Revelation Is Needed

Special revelation is God’s direct communication through specific acts and specific words, given at particular moments to particular people, reaching its climax in the person of Jesus and in the completed written Scripture. Hebrews opens by tracing this pattern: God spoke long ago through the prophets in many times and many ways, and has now spoken finally through His Son. General and special revelation are not competing accounts of God. General revelation raises the question that special revelation alone answers.

Consider what would be missing without it. Creation can tell you a Designer exists. It cannot tell you His name, His character in detail, or what He requires. Conscience can tell you that you have done wrong. It cannot tell you how that wrong is forgiven. Only a God who chooses to speak in words, preserved and transmitted with integrity, can supply that kind of specific, saving content. That is precisely what Scripture claims to be and, on the evidence, what it actually is.

Could God Have Chosen a Different Method?

God was certainly free to reveal Himself by other means had He chosen to. He could, in principle, have written the gospel in the stars or spoken audibly to every person individually. What He actually did was give His Word through human authors, preserved across centuries and transmitted with a reliability that far exceeds any other document from the ancient world. This was not a second-best solution. Written revelation can be copied, translated, carried to distant lands, and studied across generations in a way that a private audible voice, however dramatic, cannot be verified or shared.

The Climax in Jesus

This did not stop at documents. It became a person. Jesus is the fullest revelation of God the Father, and the written Scriptures are the reliable, permanent record of who He is and what He accomplished. Without that written record, the memory of Jesus would have faded into legend within a generation or two, exactly as has happened to countless other ancient figures whose deeds were never reliably recorded. Because it was written, and written under the superintending care of the Holy Spirit, it has not faded, and it will not.

Progressive Revelation, Not Given All at Once

This did not arrive all at once, as though God dictated the whole of Scripture on a single occasion and then fell silent. It unfolded progressively across many centuries, beginning with the earliest promises to Adam and Eve, developing through the patriarchs, the exodus, the law, and the prophets, and culminating in Christ and the apostolic writings that explain His significance. Each stage built on what had gone before rather than replacing it, which is why the earlier parts of the Old Testament remain genuinely authoritative even after later revelation has clarified and developed what they began.

This progressive character matters for how the doctrine is understood. It was not withheld from earlier believers out of divine reluctance. It was given in the measure and manner appropriate to each stage of God’s unfolding plan, exactly as a wise teacher does not explain every complexity of a subject in the first lesson. A patient teacher paces a course across a whole term rather than a single overwhelming lecture, and the pacing itself is part of what makes the material intelligible when it finally arrives in full.

Revelation and the Reliability of Scripture

None of this matters practically unless the record can actually be trusted to have reached us reliably. This is where the doctrine of Scripture and the doctrine of revelation meet directly. God’s choice to reveal Himself through written words rather than solely through fleeting individual experience means that every generation since the apostles has access to the same content the first hearers received, preserved through a manuscript tradition of remarkable depth and consistency. A revelation that could not be reliably transmitted would fail at the very purpose for which it was given.

This is one reason I take questions of textual transmission and manuscript reliability seriously rather than treating them as a side issue for specialists alone. If this revelation genuinely comes from God, its faithful preservation across centuries is not incidental to the doctrine. It is part of what makes it practically meaningful for anyone who was not standing at Sinai or in the upper room.

Reaching a Global Audience

It is worth adding that this kind of revelation, once given in writing, becomes portable and reproducible in a way spoken revelation to isolated individuals never could be. A private word given to one person in one place cannot be checked, shared accurately, or tested by others who were not present. A written text can be copied, translated, and examined by anyone willing to read it, which is part of why God’s chosen method has proved so durable across cultures and centuries in a way a private audible experience never could.

This is why the Bible has now been translated, at least in part, into thousands of languages, reaching communities Paul or John never imagined existed. It has travelled further and lasted longer than any other claimed revelation in human history, which is itself a kind of evidence worth weighing.

Why This Distinction Still Matters Today

The distinction between general revelation and God’s direct communication remains practically important whenever someone claims that sincere spirituality, however defined, is sufficient without the specific content of the Christian gospel. General revelation is real, and it renders every person accountable, but it was never designed to convey the saving message that a crucified and risen Jesus has borne the penalty for sin. That content arrives only through this kind of direct revelation, which is precisely why evangelism, however uncomfortable it can feel in a pluralistic culture, remains necessary rather than optional.

A god known only through creation and conscience is a god who condemns without a name to call on for mercy. What has been specially given supplies the name, the history, and the specific promise. That is not a small addition to general revelation. It is the entire difference between accountability and rescue. I would add one more thing: none of this was reserved for the theologically sophisticated. It was given in ordinary narrative, poetry, and letters, written to be read aloud in gathered congregations of fishermen, tax collectors, and slaves as readily as to scholars. Its clarity for ordinary readers is itself part of what makes it sufficient rather than a private code available only to the initiated.

So, now what?

If you have ever wondered why Christians place such weight on a book, this is the answer. Creation and conscience tell you enough to be accountable. Only the written Word tells you enough to be saved. Read it, then, not as one religious option among others but as the specific, sufficient this God has given for exactly the purpose general revelation could never fulfil.

I sometimes put the matter to congregation members this way: imagine receiving a letter from someone you love, written specifically to you, explaining exactly what they want you to know and do. Now imagine trying to reconstruct that same information only from watching their house from a distance, never reading a single word they wrote. The second method might tell you something is going on. It would never tell you what the letter actually says. This is the letter. Creation and conscience are the house observed from a distance.

There is a further practical dimension worth naming plainly. Because this revelation was written rather than left as private, unrepeatable experience, it can be taught systematically to children, examined critically by sceptics, and translated faithfully across languages and cultures without depending on the continued presence of the original recipients. A tradition passed down only through memory and private testimony grows less reliable with each generation that repeats it. A written record, carefully copied and checked against earlier copies, does not degrade in the same way, which is part of why God’s chosen method of communication has proved so durable.

Long ago, at many times and in many ways, God spoke to our fathers by the prophets, but in these last days he has spoken to us by his Son, whom he appointed the heir of all things, through whom also he created the world.
