The Knowable God

Picture Paul on the Areopagus in Athens, mid-first century. He has walked through the city and noted its altars and shrines and statues to gods of every conceivable category. One inscription stops him: "To the unknown god." The Athenians had hedged their bets and built an altar for the deity they might have missed. It is, in its way, a monument to despair. Paul does not agree with the inscription. He tells them that what they worship as unknown, he is about to declare. That move from unknown to declared is the whole logic of Christian revelation. God is not hidden. He has spoken.

The world has already heard something

Long before anyone opens a Bible, creation has been making its case. "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" (Ps 19:1-2). David is not gesturing at a vague aesthetic impression. He says the speech is continuous, the knowledge is real, and it goes everywhere: "Their voice goes out through all the earth, and their words to the end of the world" (Ps 19:4).

Paul draws the same conclusion in Romans 1. "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" (Rom 1:19-20). Two things surface through creation: eternal power and divine nature. Not a blur of spiritual energy, but a being of overwhelming strength and distinct character. The night sky does not just impress. It testifies.

Paul makes the same point in Athens. God arranged the times and boundaries of human dwelling "that they should seek God, and perhaps feel their way toward him and find him. Yet he is actually not far from each one of us, for 'In him we live and move and have our being'" (Acts 17:27-28). The created order was designed as an invitation. God placed humanity inside a world that points outward and upward so that searching would be reasonable and finding possible.

What creation cannot say

General revelation is real, and it is not enough. The same Romans passage that names what can be known through creation immediately registers the human failure to respond to it: "For although they knew God, they did not honor him as God or give thanks to him" (Rom 1:21). The witness was clear. Knowing about God and knowing God are different things.

Creation tells us God is powerful and that the world is not self-caused. It does not tell us God is merciful toward sinners. It does not tell us his name, his purposes in history, or what he intends to do with human guilt. A person standing on a cliff above the ocean knows the sea is vast and formidable. That knowledge does not tell them how to navigate it. Natural theology produces accountability, not salvation. It shows that God exists and that suppressing that knowledge is culpable, but it cannot get anyone home.

Then he spoke

Hebrews opens with a sentence that reorders the question. "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" (Heb 1:1-2). Notice what the verse does not say. It does not say that human beings, through sufficient effort, finally reached upward and caught something of God. It says God spoke. The subject is God. The action is speaking. The initiative is his.

This is the pattern across the Old Testament. God called Abraham out of Ur when Abraham was not looking for him (Gen 12:1). God spoke to Moses from a burning bush Moses had not gone looking for (Ex 3:2-4). God pursued Elijah under the broom tree while Elijah was running away (1 Kgs 19:5-9). Revelation is initiative from God's side. The movement is downward toward us before it is ever upward from us. That is the shape of all genuine knowledge of God.

The Son who makes him known

The prophets were real and the word they carried was authoritative, but they were partial. Each caught a facet. None was the full light. Then, as Hebrews says, in these last days God spoke by his Son, one "who is the radiance of the glory of God and the exact imprint of his nature" (Heb 1:3). John puts it this way: "No one has ever seen God; the only God, who is at the Father's side, he has made him known" (Jn 1:18).

The verb John uses is exegeomai, the root of our word "exegesis": to lead out, to unfold. Jesus does not merely represent the Father. He exegetes him. Every question about what God is like finds its answer in the person who sits with tax collectors, weeps at a tomb, and goes to a cross for people who scattered and denied him. The incarnation is revelation at its highest concentration.

The Spirit who brings it home

There is still a gap between hearing about God and knowing him. Paul addresses it in 1 Corinthians 2: "What no eye has seen, nor ear heard, nor the heart of man imagined, what God has prepared for those who love him" these things God has revealed through his Spirit, who "searches everything, even the depths of God" (1 Cor 2:9-10). Paul is not describing a private mystical experience. He is speaking of the gospel itself, what he calls "a secret and hidden wisdom of God" (v. 7). The Spirit takes what God declared in Christ and moves it from information into acquaintance.

Knowing the temperature outside and stepping through the door are different things. General revelation tells you there is a sun. Scripture tells you its name and its purposes. The Spirit brings you out of the building into the light.

Why this changes everything

If God were silent, we would be left with what the Athenians had: an altar to an unknown god, a monument to reverent guesswork. He has spoken. He speaks in creation continuously, in Scripture specifically, and in his Son finally and fully. That sequence is not accidental. It is the posture of a God who wants to be known.

This bears directly on how we read the Bible. We do not approach the text as archaeologists sifting rubble, hoping to reconstruct a God who has gone quiet. We approach it as a conversation already in progress, one that God started and has been sustaining for centuries. The question has never been whether we can reach high enough to find him. The question is whether we will listen to a God who has already spoken.

Before your group opens the text this week, ask them one question: who started this conversation? Let that answer settle before you read a single verse.
