Leviticus 20:18 and God's relationship design?
How does Leviticus 20:18 relate to respecting God's design for relationships?

Context and Wording of the Command

“If a man lies with a woman during her menstrual period and has sexual relations with her, he has uncovered her nakedness; they have both been cut off from their people. He has exposed her flow, and she has uncovered the source of her blood.” (Leviticus 20:18)


Why This Matters in God’s Design

- God created sexuality for covenant intimacy (Genesis 2:24).

- He also built physical rhythms into a woman’s body (Psalm 139:13–16).

- By forbidding intercourse during menstruation, God teaches that even marital intimacy is to honor His order, timing, and boundaries.

- The law highlights that bodies and blood are sacred, not casual (Leviticus 17:11).

- Violating a boundary God sets—even in marriage—shows disregard for His wisdom and therefore disrespects the relationship itself.


Underlying Principles the Law Reveals

- Reverence for life and blood: blood symbolizes life (Leviticus 17:14).

- Protection of the woman: menstruation can involve discomfort and heightened susceptibility to infection.

- Self-control within marriage: holiness means every desire is brought under God’s rule (1 Corinthians 9:27).

- Community purity: Israel’s health and holiness were intertwined; deliberate defilement fractured fellowship (Numbers 5:1–4).


Continuing Relevance under the New Covenant

- Ceremonial penalties no longer apply as they did in Israel (Hebrews 10:1).

- The moral lesson—honor God’s boundaries, cherish your spouse’s body, and practice self-denial—still stands (Hebrews 13:4).

- Believers are temples of the Holy Spirit; impure choices grieve God and harm witness (1 Corinthians 6:18–20).

- Respect for God-given physical cycles affirms that He is Lord over every dimension of marriage, not just over church life.


Other Scriptures Echoing the Same Heart

- Leviticus 15:24 – temporary uncleanness for touching menstrual blood.

- Ezekiel 18:6; 22:10 – righteous man “does not approach a woman during her impurity.”

- 1 Thessalonians 4:3–5 – God’s will is sexual sanctification.

- 1 Peter 1:15–16 – “Be holy in all you do.”


Practical Applications Today

- Communicate and plan intimacy in a way that honors your spouse’s comfort and God’s design.

- Cultivate self-control; abstaining for a time can deepen spiritual unity (1 Corinthians 7:5).

- View every physical boundary as an opportunity to prefer your spouse and worship God.

- Teach children that God’s rules are protective, not punitive; they safeguard flourishing relationships.


Key Takeaways

- Leviticus 20:18 preserves the sanctity of both marriage and the female body.

- God’s design includes rhythms and limits that invite trust and obedience.

- Respecting those limits today demonstrates love for God, for one’s spouse, and for the body God fashioned.
