Sermons on Acts 20:21
The various sermons below converge on the essential theological conviction that repentance and faith are inseparably linked components of true conversion, each indispensable and always present together in the believer’s experience. They emphasize repentance as a divine, internal change of mind or heart—a “metanoia”—that precedes or coincides with faith, rather than a mere external act or legalistic work. This repentance is portrayed as a radical turning from sin and self toward God, not requiring perfection but a genuine reorientation of the will that inevitably produces outward transformation. Several sermons use vivid analogies—such as a military about-face, chemical bonding, or a marathon race—to illustrate the dynamic and ongoing nature of repentance and faith as a unified process. Theologically, these messages stress that both repentance and faith are gifts from God, not human achievements, and that the gospel’s power lies in this supernatural work of the Spirit, which results in visible, lasting change and reconciliation with God.
Despite these shared convictions, the sermons differ in their emphases and nuances. Some highlight the logical or chronological order, insisting repentance must precede faith as the necessary recognition of sin and need for reconciliation, while others stress their simultaneity and mutual authentication, warning against separating them in preaching or practice. One sermon uniquely critiques modern trends that separate church belonging from genuine conversion, underscoring the necessity of conscious, self-aware repentance and faith. Another sermon focuses on the ongoing, lifelong nature of repentance, distinguishing it from a one-time event and emphasizing the depth of repentance as proportional to the depth of gospel experience. The use of metaphors varies as well—from chemical reactions to wedding unions—each shaping the understanding of how repentance and faith function together. Some sermons also address the pastoral dangers of legalism, antinomianism, or experiential Christianity that neglects objective reconciliation, while others emphasize the immediate forgiveness granted upon full repentance and the dual aspects of forgiveness and deliverance through the Spirit.
Acts 20:21 Interpretation:
Repentance: A Divine Change of Heart for Salvation (Calvary Baptist Church of Live Oak) offers a nuanced interpretation of Acts 20:21 by emphasizing the inseparability of repentance and faith, arguing that true saving faith always includes repentance and vice versa. The sermon delves into the Greek term "metanoia," explaining it as a change of mind rather than a work or mere cessation of sin, and uses the analogy of changing one’s mind about feeding children sugar to illustrate how repentance is an internal transformation that leads to outward change, but not perfection. The preacher is careful to distinguish repentance from legalistic works, stressing that it is a God-given, internal shift in perspective about sin, self, and the Savior, which then manifests in a changed life. This interpretation is distinct in its linguistic focus on the Greek and its practical analogy, as well as its insistence that repentance is not a human work but a divine gift.
Understanding True Conversion: Repentance and Faith (MLJTrust) interprets Acts 20:21 as the definitive summary of the two essential elements of conversion: repentance toward God and faith in the Lord Jesus Christ. Dr. Martyn Lloyd-Jones highlights the order and necessity of both, arguing that repentance must precede faith in the Pauline sense, because one must first recognize the need for reconciliation with God before trusting in Christ for salvation. He frames conversion as the first conscious act of the regenerate soul, a turning from the old life to the new, and insists that both repentance and faith are indispensable and always present in true conversion. This interpretation is notable for its focus on the logical and theological order of repentance and faith, and for its insistence on the universality and timelessness of this pattern in all true Christian experience.
True Conversion: A Radical Transformation in Christ (Ligonier Ministries) interprets Acts 20:21 as a comprehensive summary of the gospel’s call, emphasizing that true conversion is a simultaneous turning from sin (repentance) and turning to Christ in faith. The sermon uniquely highlights the inseparability of repentance and faith, referencing Calvin’s distinction that they should be “joined rather than confused.” It uses the metaphor of “worship thieves” (from Calvin) to describe humanity’s natural state, and insists that conversion is not merely an emotional or cultural shift but a supernatural work of the Holy Spirit that results in a visible, radical transformation. The sermon also critiques modern church trends that separate belonging from believing, arguing that Acts 20:21 demands a conscious, self-aware break from sin and a personal trust in Christ, not just community participation.
Transforming into Christ's Likeness: A Spiritual Journey (SermonIndex.net) offers a vivid analogy for repentance in Acts 20:21, likening it to a military “about turn”—a 180-degree reversal from sin and the world toward God. The sermon stresses that repentance and faith are “joined together” by God and must not be separated in gospel preaching, using the wedding phrase “what God has joined together, let no man separate” to reinforce this. It critiques the “other gospel” that omits repentance, arguing that faith without repentance is a dead, incomplete message. The analogy of a marathon race is used to illustrate the ongoing nature of the Christian journey, with repentance as the initial turn in the right direction and faith as the ongoing trust in Christ.
Embracing Reconciliation: The Path to True Repentance (SermonIndex.net) interprets Acts 20:21 as a “double message” of repentance and faith, inseparably linked for the forgiveness of sins. The sermon uses the story of a king releasing a prisoner who admits guilt as a metaphor for the necessity of taking full responsibility for one’s sin in repentance. It emphasizes that repentance is not the completion of sanctification but the decisive turning away from sin, even if the struggle continues, and that faith must follow this turn for forgiveness to be real.
Strength Through Trials: The Journey of Repentance and Faith (SermonIndex.net) provides a unique chemical analogy for Acts 20:21, comparing repentance and faith to the combination of hydrogen and oxygen to make water, or sodium and chlorine to make salt—separating them destroys the intended result. The sermon also uses the analogy of positive and negative electrical charges, stating that repentance (negative) and faith (positive) are both required for the “current” of the gospel to flow. It further interprets repentance as a continual, deepening process, not a one-time event, and links it to the biblical image of turning from idols to God, emphasizing the need for a total, not partial, turn.
Acts 20:21 Theological Themes:
Repentance: A Divine Change of Heart for Salvation (Calvary Baptist Church of Live Oak) introduces the theme that repentance is not a human work but a divinely granted change of mind, which is essential for salvation and inseparable from faith. The sermon also addresses the danger of both legalism and antinomianism, arguing for a "middle way" where repentance is neither a meritorious work nor an optional add-on, but the evidence of genuine faith. It further explores the idea that repentance is not about achieving sinless perfection but about a fundamental reorientation of the heart and will toward God, which will inevitably result in a changed life, though not a flawless one.
Understanding True Conversion: Repentance and Faith (MLJTrust) presents the theme that the essential and permanent elements of conversion are repentance and faith, and that these are not variable or culturally contingent but are always present in true Christian experience. Dr. Lloyd-Jones also develops the idea that repentance must come first because the primary problem of humanity is a broken relationship with God, and that the purpose of Christ’s work is to reconcile us to God, not merely to provide subjective experiences or happiness. He warns against a Christianity that focuses on experience or feelings at the expense of objective reconciliation with God, and insists that the pattern of repentance and faith is consistent across all times, cultures, and revivals.
True Conversion: A Radical Transformation in Christ (Ligonier Ministries) introduces the theme that repentance and faith are not only simultaneous but mutually authenticating—“a lack of one falsifies any credible claim to the other.” It adds the theological nuance that both are gifts from God, not human achievements, and that the church’s integrity depends on maintaining this standard for membership and community life. The sermon also explores the danger of “apparent exclusivity” in the church, arguing that clarity about conversion serves both believers and seekers by preserving the gospel’s distinctiveness.
Transforming into Christ's Likeness: A Spiritual Journey (SermonIndex.net) presents the theme that repentance is not merely a desire to stop sinning but a wholehearted, 100% longing to give up all that displeases God, even if actual victory is gradual. It also introduces the idea that the omission of repentance from the gospel is not a minor error but spiritual death, and that the “gospel of the kingdom” is not just forgiveness but righteousness, peace, and joy in the Holy Spirit—an ongoing transformation.
Embracing Reconciliation: The Path to True Repentance (SermonIndex.net) adds the theme that repentance is not overcoming sin but turning from it, and that God’s forgiveness is immediate for those who take full responsibility. It also highlights the “two sides of the gospel coin”—forgiveness through Christ’s blood and deliverance from sin’s power through the Holy Spirit—arguing that both are essential for true freedom.
Strength Through Trials: The Journey of Repentance and Faith (SermonIndex.net) introduces the theme that repentance is a continuous, lifelong process, not a one-time act, and that the depth of repentance determines the depth of gospel experience. It also emphasizes the distinction between sins of commission and omission, and that true repentance involves turning from all that is un-Christlike, not just obvious sins.
Acts 20:21 Historical and Contextual Insights:
Repentance: A Divine Change of Heart for Salvation (Calvary Baptist Church of Live Oak) provides historical context by addressing the debate between dispensationalists and hyper-dispensationalists regarding whether repentance is necessary for Jews and Gentiles alike. The preacher uses Acts 20:21 to argue that Paul, as the apostle to the Gentiles, preached repentance to both Jews and Greeks, thereby refuting the idea that different groups or dispensations have different requirements for salvation. The sermon also references the cultural context of the Rich Young Ruler and the Jewish understanding of Messiahship to illustrate the necessity of repentance for all.
Understanding True Conversion: Repentance and Faith (MLJTrust) situates Acts 20:21 within the broader historical pattern of Christian revivals and the unchanging nature of true conversion throughout church history. Dr. Lloyd-Jones asserts that every genuine revival and every true Christian conversion, regardless of era or culture, is marked by the same essential elements of repentance and faith, as exemplified in Acts 20:21. He also references the historical context of Paul’s farewell to the Ephesian elders, highlighting the universality of Paul’s message to both Jews and Greeks.
True Conversion: A Radical Transformation in Christ (Ligonier Ministries) provides historical context by referencing the early church’s pattern of kerygma (proclamation) followed by didache (teaching), explaining that in the first-century church, apostolic preaching called for repentance and faith before admission to the church, after which catechetical instruction followed. The sermon also discusses the cultural resistance to the idea of conversion in the modern West, noting that the contemporary suspicion of deep personal change contrasts sharply with the biblical and early Christian expectation of radical transformation.
Strength Through Trials: The Journey of Repentance and Faith (SermonIndex.net) offers historical context by referencing the Old Testament pattern of Israel’s exodus from Egypt and entry into Canaan as a two-stage picture of salvation: deliverance from slavery (forgiveness) and entry into the promised land (victory over sin). The sermon also references the Babylonian exile and the prophetic critique of “idols in the heart” (Ezekiel 14) to illustrate the depth of repentance required.
Acts 20:21 Cross-References in the Bible:

These references are marshaled to show the biblical consistency and universality of the repentance-faith pattern.
True Conversion: A Radical Transformation in Christ (Ligonier Ministries) references 1 Thessalonians 1:8-10 to illustrate the nature of conversion as “turning to God from idols to serve the living and true God,” paralleling Acts 20:21’s call to repentance and faith. It also cites James 2:19 (faith without works is dead), Acts 26:20 (Paul’s summary of his gospel as repentance and faith), Mark 2:17 (the sick needing a doctor), 1 Timothy 1:15 (Christ came to save sinners), Romans 7 (the ongoing struggle with sin), Galatians 5 (fruit of the Spirit), and 1 Corinthians 14:26 (building up the congregation) to support its interpretation and application of Acts 20:21.

Acts 20:21 Christian References outside the Bible:
Understanding True Conversion: Repentance and Faith (MLJTrust) explicitly references William James, the Harvard psychologist, and his book "The Varieties of Religious Experience," using it as an example of how psychological phenomena can mimic conversion without being true Christian conversion. Dr. Lloyd-Jones warns that not all life changes or dramatic experiences are genuine conversions, and that the defense of the Christian faith must rest on objective truth, not subjective experience. He also mentions the influence of Charles Finney’s autobiography on readers’ expectations of conversion experiences, and references John Wesley’s reflection on his Aldersgate experience, noting that Wesley later realized he had been a Christian before that dramatic event. These references are used to caution against confusing psychological or emotional experiences with the biblical pattern of repentance and faith.
True Conversion: A Radical Transformation in Christ (Ligonier Ministries) explicitly references John Calvin, quoting his statement that “we wickedly defraud God of His glory” and his teaching that repentance and faith should be “joined rather than confused.” The sermon also references Albert Einstein’s admiration for the church’s moral courage during Nazi Germany, William James’s psychological theory of conversion, and Gandhi’s autobiography as examples of secular and religious perspectives on change and conversion. Additionally, it discusses Steve Timmis and Tim Chester’s “Gospel Centered Church” and Tim Conder’s “A Church in Transition” as contemporary Christian books advocating for “belonging before believing,” critiquing their approach in light of Acts 20:21. R.C. Sproul and D. James Kennedy are also cited in the Q&A, with Sproul emphasizing the Reformation doctrine of justification by faith alone and Kennedy’s “diagnostic questions” for evangelism.
Acts 20:21 Illustrations from Secular Sources:
Understanding True Conversion: Repentance and Faith (MLJTrust) draws on secular examples to illustrate the concept of counterfeit conversion. Dr. Lloyd-Jones recounts a story from William James’s "The Varieties of Religious Experience" about a journalist and novelist who underwent a profound psychological change after seeing a great ball of light while on an Atlantic liner, leading to a dramatic shift in his life and creative process. This example is used to show that not all life-altering experiences are spiritual conversions, and that psychological phenomena can produce changes that superficially resemble Christian conversion but lack its essential elements. The sermon also references the broader field of psychology and its study of conversion experiences, warning that such phenomena can be mistaken for true spiritual transformation if not carefully distinguished by biblical criteria.
True Conversion: A Radical Transformation in Christ (Ligonier Ministries) uses several detailed secular illustrations to illuminate Acts 20:21. It recounts Langston Hughes’s story of a false conversion at a revival, highlighting the danger of external conformity without true repentance and faith. The sermon references Gina Welch’s undercover experience joining a church as an atheist, illustrating the possibility of religious participation without conversion. It also cites Albert Einstein’s observation of the church’s unique resistance to Nazi ideology, using it to show the transformative power of true conversion. The preacher shares a personal anecdote about an atheist friend in Cambridge who sought out churches for community, not faith, to illustrate the difference between social belonging and spiritual conversion. The sermon further references William James’s psychological theory of conversion and Gandhi’s lifelong spiritual quest, contrasting them with the biblical concept of knowing God through repentance and faith.
