Homiletics Analysis: Leviticus 20:6–8

Content & Intent

This Text — Content: Leviticus 20:6–8 sits within the broader holiness code of Leviticus 17–27, a section governing the practical shape of Israel’s covenant life with the LORD. The immediate context is chapter 20, which assigns penalties to specific violations already prohibited in chapter 18–19. Verses 6–8 form a tight unit addressing one particular covenant defection — turning to mediums and necromancers (those who consult the dead or spirits) — and God’s response to it. Verse 6 announces that the person who turns to mediums and necromancers has prostituted himself, and that God Himself will set His face against that person and cut him off from his people. Verse 7 issues the positive counterpart: “Consecrate yourselves, therefore, and be holy, for I am the LORD your God.” Verse 8 grounds the command in God’s sanctifying work: “Keep my statutes and do them; I am the LORD who sanctifies you.” The unit moves from prohibition and penalty (v. 6) to positive command (v. 7) to covenantal grounding (v. 8) — a complete theological argument in three verses.

This Text — Intent: God is not merely regulating one category of religious behavior. He is confronting the root disposition beneath the prohibited act: the impulse to seek knowledge, security, and guidance from any source other than the LORD Himself. Turning to a medium is, in the passage’s own logic, spiritual prostitution — it is the covenant people going to another. God’s intent through this passage is to call His people back to exclusive reliance on Him by confronting the idolatrous impulse at its root, grounding the call to holiness not in Israel’s moral performance but in who God is and what He is doing in them (“I am the LORD who sanctifies you”). The passage aims to expose the false refuge of occult consultation and replace it with the only true source of knowledge, security, and guidance — the LORD Himself, who is already at work making His people holy.

Subject Sentence: Seeking forbidden spiritual sources is covenant betrayal; holiness flows from the LORD who sanctifies.

Primary Claim: God forbids His people from seeking guidance or security from occult sources because He alone is the legitimate source of all that mediums falsely promise — and because He is already at work sanctifying those who are His. The call to holiness here is not a demand issued from a distance but a summons consistent with what God is actively doing in His covenant people.

Interpretive Evaluation

The nature of the prohibition — behavioral rule or root-idol diagnosis? A common reading, especially in popular preaching contexts, treats verses 6–8 as a behavioral regulation — “don’t do this specific thing” — and moves quickly to contemporary applications (Ouija boards, horoscopes, psychics). This reading is not wrong as far as it goes, but it stops short. The passage’s own language — “prostitutes himself” (v. 6) — signals that the prohibition is reaching beneath the behavior to the disposition it expresses. Prostitution language in the Old Testament consistently denotes covenant infidelity, the transfer of trust and intimacy from the covenant LORD to another. The Keller idol-diagnosis lens is directly warranted here: consulting mediums is a symptom of a deeper root — the refusal to trust the LORD with what cannot be controlled or known. To preach this passage as behavioral regulation without addressing the underlying trust-deficiency is to address the symptom and leave the disease.

The penalty — “cut off from his people” — and its applicability: Some traditions (particularly those with a strong Israel/Church distinction in a dispensational frame) treat the cutting-off penalty as strictly Mosaic-covenantal and inapplicable in the New Covenant era. This is a case where the distinction should be acknowledged but qualified. The specific legal penalty belongs to the Mosaic administration. But the underlying logic does not — that covenant infidelity ruptures relationship with God and community is a principle running from Genesis to Revelation. The New Testament does not promise immunity from spiritual consequences to covenant people who practice ongoing occult engagement (see Acts 19:19; Galatians 5:20 where sorcery appears in the works of the flesh). The Reformed reading acknowledges the covenantal-administrative specificity of the death penalty while maintaining that the relational and spiritual principle is trans-covenantal.

“I am the LORD who sanctifies you” — divine monergism or synergistic cooperation? Wesleyan/Arminian reading tends to read verse 8 as a partnership — “keep my statutes and I will sanctify you” — with the human keeping of statutes as the condition for divine sanctification. This reading is worth qualifying: obedience is real and required (v. 8a), and the passage does not dissolve human responsibility. But the grammar does not support conditionalism. The clause “I am the LORD who sanctifies you” is not a conditional promise hanging on v. 8a — it is a covenantal self-identification, the grounds for the obedience. The structure is: “Keep statutes — because I am the one already sanctifying you.” This is consistent with the Reformed understanding of sanctification as grounded in God’s prior work, with human obedience as the responsive and instrumental expression of that prior grace — not the cause of it.

The Reformed reading: Verses 6–8 form a unit in which prohibition, consecration-command, and covenantal grounding are inseparable. The prohibition is root-level (covenant fidelity, not behavioral rule-keeping). The penalty is relationally serious (not merely legal). The positive command to holiness is grounded in God’s prior sanctifying work. The Reformed reading holds all three together: God confronts idolatrous trust-substitution, commands holiness, and grounds that command in what He is already doing. This is not Pelagianism (be holy so God will accept you) nor antinomianism (God sanctifies you, so behavior is secondary) — it is the Reformed indicative-imperative structure operating precisely as it should.

Key Canonical Support

• Deuteronomy 18:9–14 — The most extensive Old Testament parallel; explicitly lists mediums, necromancers, and diviners as “abominations” that were among the reasons Canaan was dispossessed. Provides the canonical context for why this prohibition is not arbitrary but is connected to the holiness of the land and God’s people.

• Isaiah 8:19–20 — “Why do you consult the dead on behalf of the living? To the law and to the testimony!” — directly names the trust-substitution at the root of occult consultation and redirects covenant people to the word of God as the only legitimate source of guidance and knowledge.

• 1 Samuel 28:3–19 — Saul’s consultation of the medium at Endor is the canonical case study in what Leviticus 20:6 prohibits. Saul, having been cut off from God’s word (28:6), turns to a medium — illustrating that occult consultation arises precisely from the breakdown of trust in God’s revealed guidance.

• Acts 19:17–20 — New converts at Ephesus burn their occult books publicly upon receiving the gospel; the passage demonstrates that the New Testament assumes the same root-level incompatibility between occult practice and covenant life with God. The Leviticus principle persists under the New Covenant.

• Galatians 5:19–21 — “Sorcery” (pharmakeia) appears explicitly in Paul’s list of works of the flesh, reinforcing that occult engagement is categorically incompatible with life in the Spirit — the New Covenant form of what Leviticus 20 addresses covenantally.

Aim: To call the reader to examine not only behaviors but the underlying trust-deficiencies that occult consultation expresses, and to re-anchor their pursuit of knowledge, security, and guidance in the LORD who is already at work sanctifying them.

Subject Sentence & Primary Claim (restated)

Subject Sentence: Seeking forbidden spiritual sources is covenant betrayal; holiness flows from the LORD who sanctifies.

Primary Claim: God forbids His people from seeking guidance or security from occult sources because He alone is the legitimate source of all that mediums falsely promise — and because He is already at work sanctifying those who are His. The call to holiness here is not a demand issued from a distance but a summons consistent with what God is actively doing in His covenant people.

Applications (Five)

1. [Mind/Belief] — Reframe what occult consultation actually is. The impulse to consult mediums, horoscopes, psychics, or any source of hidden knowledge is not merely a superstition problem or a behavioral lapse — it is a trust problem. When we reach for those sources, we are acting as though the LORD is either inaccessible, unreliable, or insufficient for what we need to know. This passage names that move for what it is: spiritual prostitution, a turning from the one who is already present and already speaking. Before any behavioral change is possible, the reader must reframe the diagnostic category: this is not a quirk or a harmless interest — it is a declaration, however unconscious, that God is not enough.

2. [Affections/Worship] — Let the weight of “I will set my face against you” land. The phrase “set my face against” is not administrative language — it is relational and personal. It describes not the withdrawal of God’s benefits but the turning of His active opposition toward a person. The reader who has grown comfortable with low-level occult engagement (daily horoscopes read “for fun,” casual interest in spiritual personalities, persistent return to anxious fortune-seeking) should feel the weight of this: the covenant LORD takes it as personally as a spouse takes infidelity. The appropriate affective response is not primarily guilt management but a renewed fear of the LORD — a genuine, sobering re-orientation of whom one is dealing with when God says “I am the LORD your God.”

3. [Will/Behavior] — Identify and close the specific access points. Consecration (v. 7) is not an attitude — it is a concrete act. For the original readers, it meant the removal of specific objects and the cessation of specific practices. For the contemporary reader, the same concreteness applies. This application calls for a specific inventory: What sources of hidden knowledge, false security, or spiritual curiosity are you regularly accessing that operate outside the LORD’s revealed word? Apps, content, practices, relationships that function as substitute oracles. Name them. Remove access. The application is not “generally be more godly” — it is the specific act of closing what has been left open.

4. [Mind/Belief] — Receive the indicative that grounds the imperative. “I am the LORD who sanctifies you” is not a reward waiting at the end of successfully kept statutes — it is the foundation beneath the command. This means the reader does not pursue holiness in order to earn sanctification; they pursue holiness because they are already being sanctified by the LORD. For the reader who has experienced failure in this area — whether occult engagement in the past or present — this is the word that changes everything: God’s sanctifying work is not contingent on your unbroken track record. You are not fighting toward holiness alone from below; you are being made holy from above by the One who has bound Himself to you in covenant. Receive this. It changes not just the motivation but the posture.

5. [Affections/Worship] — Re-orient the desire for knowledge, security, and guidance back to the LORD. People do not consult mediums out of mere curiosity — they do it because they want to know what they cannot know, control what they cannot control, and be secure in what threatens them. The LORD is not indifferent to those desires. He is the God who speaks, guides, and provides. This application calls for a worship re-orientation: bring the specific anxieties, unknowns, and fears that occult consultation promises to address — and bring them to the LORD instead. Through prayer, through Scripture, through the community of God’s people. The question is not only “stop doing this” but “start going here with what drove you to it.” The desire for security and knowledge is not the problem; the redirected object is.

Theological Importance

Theological Importance: This passage teaches that the LORD is a covenant God who takes exclusive claim on the trust, loyalty, and dependence of His people — not as an arbitrary demand but as the natural consequence of who He is and what He has done. The holiness He commands is not a second tier of religious achievement beyond basic obedience; it is the shape of a life oriented entirely toward the One who is holy. Crucially, the passage reveals that God’s role in holiness is not passive or waiting — He is “the LORD who sanctifies,” the active agent of the holiness He commands. This means that the command to holiness and the provision for it originate from the same source: the LORD Himself. Occult consultation is therefore not merely a rule violation but a theological absurdity — going elsewhere for what only the Giver of life possesses and freely provides.

Reformed Theological Significance

Reformed Theological Significance: This passage is a clean instance of the Reformed indicative-imperative structure embedded in the Mosaic covenant itself: the command to holiness (imperative) is grounded in God’s prior sanctifying work (indicative). This is not a New Testament innovation read back into Leviticus — it is present in the text’s own logic. The Reformed tradition’s insistence that obedience is the response to grace, not the cause of it, is not merely Pauline — it runs through the whole structure of covenant-keeping in the Old Testament. The passage also illustrates the idol-diagnostic work the Reformed tradition consistently emphasizes: the prohibited behavior (consulting mediums) is the surface expression of a deeper covenant defection (misplaced trust), and faithful exposition must reach the root, not merely address the symptom. Finally, the language of exclusive covenant loyalty — “I am the LORD your God” — anticipates the New Covenant’s fullest expression of this claim, in which Christ Himself is the one in whom all the knowledge, security, and guidance that mediums falsely promise is genuinely and completely found.

Main Takeaway

There is nothing a medium can give you that the LORD has not already promised to be for you — and when you go looking elsewhere, you are not just breaking a rule, you are telling God He is not enough. He is not indifferent to that. But here is what the passage will not let you miss: the same God who says “I will set my face against you” also says “I am the LORD who sanctifies you.” He is already at work making you holy. Go back to Him — with your fears, your unknowns, your need for security — and find there what no other source can offer.

Preaching/Teaching Pitfalls

• Reducing the passage to a list of prohibited practices without diagnosing the root. It is easy to preach a behavioral checklist (no Ouija boards, no horoscopes, no psychics) and miss the passage’s own language entirely. The word “whoring” is the exegetical key — the prohibition is reaching the idolatrous disposition beneath the behavior. A sermon that stops at behavior modification has not preached this passage; it has preached a rule with biblical decoration. The root is trust-deficiency and misplaced covenant loyalty. Preach that.

• Treating the penalty as the rhetorical climax rather than the ground of the command. “I will set my face against him” is meant to establish the seriousness of the covenant claim, not to be the sermon’s emotional peak. The passage moves from penalty to command to ground — the real climax is verse 8b: “I am the LORD who sanctifies you.” Sermons that dwell too long on the threat and too briefly on the grounding indicative leave the congregation under condemnation rather than under the call to renewed covenant trust.

• Disconnecting verse 8b from verses 7–8a (reading sanctification as a reward rather than a ground). The Wesleyan-Arminian misreading identified in the Interpretive Evaluation — “keep statutes and then I will sanctify you” — is a natural grammatical misread and a common homiletical move. The preacher must be explicit: the sanctification statement is not at the end of a conditional chain; it is the covenantal foundation of the command. This distinction changes the motivational structure of the entire sermon.

• Applying the text only to dramatic occult engagement and missing the everyday forms. When preachers say “medium” and “necromancer,” congregations think Halloween and horror films — not their daily horoscope, not the astrology app they check anxiously each morning, not the spiritual personality they follow online for vague guidance, not the persistent magical thinking about omens and signs. The preacher should be explicit that the root impulse — seeking to know the unknown, control the uncontrollable, secure the uncertain through non-revealed means — shows up in many culturally acceptable forms. Naming specific contemporary access points is not sensationalism; it is the concreteness the passage requires.

• Omitting the redemptive-historical tether — preaching Leviticus 20 without Christ. The passage’s claim that the LORD sanctifies His people reaches its fullest expression in Christ, who is made to us “wisdom from God, righteousness and sanctification and redemption” (1 Cor. 1:30). The New Covenant believer is not merely told to “be holy as I am holy” — they are united to the Holy One Himself. Preaching this passage without that tether leaves the congregation under an Old Covenant demand without the New Covenant provision. The call to exclusive covenant loyalty and the promise of God’s sanctifying work are not abolished in Christ — they are fulfilled and deepened.

• Moralizing the “consecrate yourselves” command without naming the gospel motivation. Following Clowney’s anti-moralism principle, the command of verse 7 must not be reduced to “try harder to be different.” Consecration in the Old Testament is not self-generated religious achievement — it is the active alignment of one’s life with what God has already declared one to be. The preacher must name the gospel motivation: you are called to be holy because you are the LORD’s, because He has claimed you, and because He is the one doing the sanctifying work. “Therefore be holy” is a summons to become what you already are in covenant relationship with God.
