Sermons to the Natural Man

In Short

Written with a grave sense of pastoral obligation, this collection of twenty theological discourses systematically dismantles the moral illusions of the unrenewed human heart. The author demonstrates that intellectual agreement with Christian doctrine cannot substitute for an inward awareness of personal sin. By applying the absolute demands of divine law to human conscience, these sermons aim to awaken a deadened sensibility, proving that human character inevitably fails under divine inspection. The work endures as a classical, uncompromising expression of Reformed theology, offering an exhaustive psychological analysis of guilt, moral paralysis, and the absolute necessity of divine grace.

The Story

The intellectual arc of this volume moves from a stern diagnostic of human sinfulness to the absolute necessity of divine intervention. It opens with an urgent declaration that preaching must first apply the law with uncompromising clarity before the comfort of the gospel can be understood or received. Mankind, operating in a state of practical unbelief, routinely relies upon personal morality or intellectual assent to escape the frightening reality of future judgment. However, the text demonstrates that human indifference and false theorizing cannot alter the immutable nature of God or the relentless operation of His righteous laws.

As the argument advances, it subjects the internal workings of the human spirit to an exhaustive examination. God possesses an absolute, exhaustive knowledge of every secret thought and hidden motive, inspecting the soul with a holiness that instantly exposes all self-righteousness as worthless. Confronted by this terrifying divine scrutiny, every human defense collapses, leaving the world guilty and silent before the heavenly tribunal. The text proves that admiring or praising moral excellence is entirely different from actually possessing or loving it; natural conscience frequently approves of a righteousness that the natural will consistently refuses to practice.

This internal conflict places the individual under a state of spiritual bondage. The divine law, which was originally ordained to give life, becomes an instrument of death and torment to a fallen nature, acting as a constant, restrictive weight upon the sinner's desires. The natural man discovers that his will is thoroughly alienated from God, rendering him incapable of originating holy desires or rescuing himself from moral ruin. Human reason and natural religion offer no escape, as even the pagan world stands condemned by its own failure to live up to the light of natural conscience.

The argument reaches its climax by establishing that salvation is completely impossible without a direct, sovereign operation of God the Holy Spirit. The Holy Spirit serves as the indispensable link between God and man, convincing the soul of the reality of the unseen eternal world, awakening the slumbering conscience, and enabling the sinner to exercise saving faith. Man cannot dictate terms to his Creator or alter the conditions of divine mercy. To receive redemption, the soul must abandon all rationalistic pride, recognize its total spiritual poverty, and adopt the humble, teachable posture of a little child, receiving the substituted sacrifice of Jesus Christ as its only hope.

How It Unfolds

The mandate of the law The preacher establishes that the divine law must be applied to the conscience with uncompromising severity before any individual can truly feel their need for redemption. Practical unbelief and moral indifference dominate the natural heart, blinding individuals to the reality of the coming judgment.

The exhaustive divine scrutiny God searches every secret movement and hidden thought of the human spirit with absolute precision. Under this penetrating inspection of pure holiness, all human claims to personal righteousness wither away, leaving every individual utterly condemned at the bar of divine justice.

The bondage of the natural will Humanity exists in a state of spiritual slavery, where the conscience approves of moral goodness but the heart actively pursues evil. The holy law of God becomes a agonizing restraint and a source of torment to a fallen nature that cannot fulfill its demands.

The necessity of the Holy Spirit Left to himself, man cannot perceive the reality of the eternal world or generate a single holy impulse. The Holy Spirit must directly enlighten, enliven, and empower the soul, acting as the sole agent who connects the alienated sinner to the blessings of salvation.

The posture of child-like submission The soul must surrender all intellectual pride and self-righteous theorizing, accepting God's sovereign terms of mercy without reservation. Salvation requires an inward acknowledgment of total helplessness and a humble, receptive heart that relies entirely upon the vicarious atonement of Christ.

The People

The Preacher The authorial voice carries an intense, solemn feeling of responsibility, conscious that his words will serve either as a means of spiritual life or an occasion of spiritual death. He acts as a rigorous spiritual anatomist, deliberately prioritizing the hard work of convicting the reader of sin over offering easy comfort.

The Natural Man The unregenerate human being who lives in a state of practical unbelief, self-deception, and moral lethargy. Though he may possess intellectual culture, fine earthly health, or high social standing, his inward will remains completely alienated from God and bound to spiritual slavery.

The Searcher of Hearts The triune God, whose holy essence relentlessly inspects every secret thought and inner motive of human existence. As an unchangeable Judge, His exhaustive knowledge leaves no room for human excuses, yet in sovereign mercy He offers redemption through the substituted sacrifice of His Son.

The Holy Spirit The third Person of the Godhead, presented as the vital agent who enlightens the darkened human mind and awakens the deadened conscience. He breaks through human blindness, making the unseen realities of eternity vivid to the soul and enabling the sinner to accept divine grace.

In Its Own Voice

"It is in vain to offer the gospel unless the law has been applied with clearness and cogency."

The author insists that a sinner must understand their utter condemnation under God's righteous standard before they can appreciate the offer of salvation.

"Our most darling theories, by which we may have sought to solace our souls in reference to our future destiny, if false, will be all ruthlessly torn away, and we must see what verily and eternally is."

Here the text warns that human philosophical defenses and theological speculations will completely vanish when the soul stands directly before God.

"The law of God shows itself in the human soul, in the form of a sense of duty."

The writer explains how the immutable divine law becomes an active, unavoidable force within every person's internal consciousness.

What It's Really About

At its core, this volume confronts the fundamental self-deception of human self-reliance and moral optimism. It argues that humanity consistently underestimates the severity of divine holiness and the depth of its own internal corruption. By analyzing the psychological mechanisms of guilt, conscience, and moral failure, the text demonstrates that intellectual admiration for virtue is not the same as loving God. The work insists that the invisible, eternal world is the ultimate reality, and that human reason is utterly powerless to rescue a soul from spiritual death. Ultimately, it asserts that true religion begins only when an individual experiences complete moral helplessness under the law, forcing them to depend entirely upon the sovereign, unearned mercy of God.

Why Read It Today

This work appeals directly to readers interested in historic Reformed theology, classic pulpit eloquence, and deep psychological examinations of human guilt. It provides a rare, uncompromising glimpse into nineteenth-century Presbyterian thought, written with rigorous logic and absolute theological consistency. Reading these discourses offers an intellectually bracing experience, defined by precise arguments and a solemn, lofty tone that refuses to flatter the reader's self-esteem.

Modern readers must navigate dense, formal nineteenth-century prose, lengthy sentence structures, and untranslated Latin and Greek footnotes. The text presents a worldview entirely unconcerned with contemporary sensitivities, uncompromisingly insisting upon strict divine justice, eternal retribution, and the total depravity of the human will. It explicitly rejects modern secular notions of human progress, rationalism, and moral self-improvement. Yet for those willing to engage its formidable demands, the book leaves a lingering impression of profound solemnity, offering a masterclass in how classical theology applies moral law directly to the secret recesses of the human conscience.
