Why is obedience to Leviticus 20:18 important for honoring God's holiness? Setting the Verse in Context Leviticus 20 sits within a larger “holiness code” (Leviticus 17–26). The Lord distinguishes His covenant people from surrounding nations by prescribing practices that reflect His character. Sexual boundaries, including those concerning ceremonial uncleanness, are woven into that call to be “holy, because I, the LORD your God, am holy” (Leviticus 19:2). Understanding the Command Leviticus 20:18: “If a man lies with a menstruating woman and has sexual relations with her, he has exposed her flow and she has uncovered the source of her blood. Both of them must be cut off from among their people.” Key observations: • The command addresses sexual activity during a woman’s menstrual period. • “Cut off” points to severe covenant consequences—either formal excommunication or divine judgment. • The language ties the act to unlawful exposure of blood, a recurring symbol of life and holiness (Leviticus 17:11). Why Obedience Honors God’s Holiness • Reverence for life-blood – Blood belongs uniquely to God as the giver of life (Leviticus 17:11). – Treating it casually profanes what God has declared sacred. • Submission to God’s boundaries – Sexual intimacy is God’s gift, yet He alone sets its limits (Genesis 2:24). – Accepting those limits affirms His authority over every part of life. • Separation from pagan practices – Canaanite fertility rites often ignored any restraint; Israel was to look different (Leviticus 18:3). – Obedience marked Israel as “a people set apart” (Deuteronomy 7:6). • Protection of personal and communal purity – Bodily uncleanness spread ceremonially to others (Leviticus 15:19-33). – Guarding purity preserved the worshipping community from defilement of the sanctuary (Leviticus 15:31). • Foreshadowing Christ’s cleansing work – By highlighting mankind’s defilement, the law pointed forward to the need for perfect atonement (Hebrews 9:13-14). Broader Biblical Witness • Leviticus 18:19 echoes the same prohibition, reinforcing its seriousness. • 1 Peter 1:15-16 calls believers to the same standard of holiness grounded in God’s character. • 1 Corinthians 6:18-20 reminds Christians that bodies are temples of the Holy Spirit, bought with Christ’s blood. • Hebrews 10:29 warns against trampling that blood through irreverence. Practical Implications for Today • Honor God in every sexual decision, recognizing His right to define purity. • Treat the shedding of blood—physical or spiritual—with awe, remembering its cost in redemption. • Value the church community’s holiness; personal choices affect the whole body. • Let God’s boundaries lead to deeper gratitude for Christ, who cleanses where we fall short. Looking to Christ The law exposes our need, but Christ fulfills the holiness it demands. His blood, shed once for all, purifies consciences “from dead works to serve the living God” (Hebrews 9:14). Obedience to commands like Leviticus 20:18 is not mere rule-keeping—it becomes a living testimony that the Holy One who set the boundaries now dwells within His people, empowering them to walk in holiness. |
