When the Word Is Preached, God Speaks
Heralds of a Message We Did Not Create
Preaching as Heralding
If God has always saved by speaking, then the question that naturally follows is about the nature of preaching itself.
What does it mean, in biblical terms, to preach?
The New Testament answers this question not by pointing to method or style, but by framing preaching as the act of heralding a message that originates with God Himself.
The Greek noun kērugma and its related verb kēryssō are drawn from the world of proclamation, where a herald was commissioned to announce the words of a king, not to improve upon them, adapt them, or ensure their reception but simply to proclaim what that king had said.
This establishes the fundamental posture of Christian preaching is and what it is not. A herald does not speak on his own authority, nor does he bear responsibility for producing the response to the message he delivers. He is judged not by the reaction of the hearers, but by whether he has accurately and faithfully declared what he was sent to announce. In this sense, preaching is defined not by outcome, but by the fidelity to the message that was given.
Sender, Message, and Hearer
The language of heralding presupposes a clear structure, namely that there is a sender, a message, and an audience.
In Christian preaching, the sender is God, the message is His Word, and the hearers are those whom God addresses through that Word. This structure leaves no room for the preacher to function as an originator of meaning. He stands between God and the congregation only in the sense that he audibly delivers what God has already spoken.
This understanding of preaching protects the church from shifting its confidence away from God’s speech and toward the ideas of the messenger. When preaching is reconceived as persuasion or inspiration. Whether in the mind of the preacher or the mind of the hearer, the burden of effectiveness quietly shifts onto the preacher. The biblical vision, however, resists this by grounding preaching in divine initiative. God speaks, and the preacher serves that speech by making it known.
Preaching as Divine–Human Encounter
Because preaching is the public proclamation of God’s Word, it must be understood as a divine–human encounter rather than an exchange of information. As Jonathan Griffiths observes, when the Word is proclaimed, God Himself addresses His people.
This claim does not elevate the preacher or endow his words with some kind of intrinsic power, but acknowledges that God has chosen to work through the means of proclamation. The power of preaching lies not in the preacher’s voice, but in the reality that God has bound His speech to the declaration of Scripture.
This understanding rests upon the doctrine of Scripture as divine revelation. When Paul writes that all Scripture is breathed out by God (2 Tim. 3:16), he is not merely asserting that it is just useful; he is grounding its authority in its origin. Because Scripture comes from God, it carries divine authority, and when it is proclaimed, that authority is exercised in its hearing (Rom. 10:17).
Peter reinforces this reality when he instructs that whoever speaks in the Christian assembly must do so as one speaking the oracles of God (1 Pet. 4:11). Preaching, therefore, is not speech about God, but God’s own Words that are being mediated through human proclamation.
Authority Without Autonomy
This view of preaching establishes authority without granting autonomy. The preacher speaks with authority only insofar as he speaks God’s Word, and he possesses no authority beyond that Word. His task is not to create meaning, but to expose the meaning already present in the text of Scripture. In this way, preaching stands under the Word even as it speaks the Word, guarding both the preacher and the congregation from confusion about where the authority truly resides.
When preaching is rightly understood as heralding, the preacher is freed from the impossible task of producing spiritual results and redirected toward the faithful handling of the message entrusted to him.
Likewise, the congregation is taught to listen not for insight, but for the voice of God speaking through His Word. The encounter that takes place in preaching is not grounded in the personality of the preacher, but in the promise that God speaks when His Word is faithfully proclaimed.
God Still Speaks Through Proclamation
To say that God speaks through preaching is not to collapse the distinction between Scripture and sermon, nor to claim infallibility for the preacher’s words. Rather, it is to confess that God has bound Himself to the proclamation of His Word as the means by which He addresses His people.
This confession preserves both humility and confidence within the ministry of preaching. The preacher speaks humbly, knowing that he is a servant of the Word, and confidently, trusting that God continues to act through the means He has appointed.
Preaching, therefore, is God’s gracious condescension to reach humanity through speech. When the Word is preached, God speaks, and in that speaking He calls, comforts, corrects, and gathers His people according to His will.
