About This Study Guide

Gary Thomas opens Sacred Marriage with a question that reframes everything: "What if God designed marriage to make us holy more than to make us happy?" That single question is the engine of the entire book. Thomas argues that marriage is not primarily a romantic arrangement for personal fulfillment — it is a spiritual discipline, as rigorous and transforming as fasting, prayer, or solitude. Every frustration, every moment of tenderness, every season of boredom or passion in a marriage is raw material in God's hands for shaping us into the image of his Son. Sacred Marriage does not promise a better marriage by the time you finish it; it promises a better you — and a richer, more honest relationship with God.

This study guide is designed for use over thirteen weeks, either in a small group or as a personal study. Each week, read the assigned chapter before your group meets or before you sit down to journal. Come with the text in hand — Thomas's illustrations and stories are the lifeblood of the discussion questions, and you'll want to refer back to them. After working through the questions, spend a few minutes in the closing prayer, letting the themes of the chapter become the language of your conversation with God. If you are going through the guide as a couple, consider doing the questions separately in writing first, then sharing your answers with each other — the honesty that practice requires is itself a form of the spiritual discipline Thomas is describing.

By the end of this guide you should expect three things: a more theological understanding of why you are married, a more compassionate and humble posture toward your spouse, and a deeper awareness of how daily life in a covenant relationship reveals — and confronts — who you really are before God. Thomas does not flinch from the hard parts of marriage, and neither do these questions. Expect to be challenged, occasionally uncomfortable, and ultimately encouraged that the ordinary, sometimes difficult work of being married is one of God's most powerful tools for forming a holy people.

Week 1: Introduction — The Holy Pursuit

All 7 questions

Read the Introduction of Sacred Marriage by Gary L. Thomas. Key passages: Ephesians 5:25–32; Genesis 2:18–24.

1.Thomas frames his central question as: "What if God designed marriage to make us holy more than to make us happy?" Before reading any further, how would you have answered that question? What assumptions about marriage did you bring into this book?

2.Thomas observes that most marriage books are essentially self-help books — their goal is a better, more satisfying marriage for you. How does his reframing shift the goal? What is at stake in that shift?

Week 2: Chapter 1 — The Refining Power of Marriage

All 7 questions

Read Chapter 1 of Sacred Marriage. Key passages: Romans 5:3–5; James 1:2–4; Proverbs 27:17.

1.Thomas uses the image of marriage as a refining fire rather than a comfortable nest. In your own words, what does he mean? How does that metaphor change what you expect marriage to feel like?

2.He cites the way that living in close proximity to another person exposes character flaws we could hide when we were single. Can you identify one or two things about yourself that marriage has brought to the surface that surprised you?

+ 5 more questions

Week 3: Chapter 2 — The Revealing Power of Marriage

All 7 questions

Read Chapter 2 of Sacred Marriage. Key passages: Jeremiah 17:9; Matthew 15:18–19; 1 Corinthians 13:4–7.

1.Thomas argues that we can maintain a flattering self-image much more easily when we are alone than when we are married. Do you agree? What specifically does marriage reveal that solitude or even friendship does not?

2.He discusses how the way we treat our spouse when no one is watching is one of the truest measures of our spiritual character. How does that standard sit with you? What does it reveal?

+ 5 more questions

Week 4: Chapter 3 — The Sustaining Power of Marriage

All 7 questions

Read Chapter 3 of Sacred Marriage. Key passages: Ecclesiastes 4:9–12; Ruth 1:16–17; Song of Solomon 8:6–7.

1.Thomas describes the way a long marriage builds a kind of shared history and mutual knowledge that becomes a unique source of strength. How have you experienced that sustaining power in your own marriage — or longed for it?

2.He draws on the image of two people leaning against each other for warmth — from Ecclesiastes 4 — as a picture of the practical, earthy companionship marriage is designed to provide. How does the ordinary dailiness of marriage — not just its romantic peaks — serve as a form of grace?

+ 5 more questions

Week 5: Chapter 4 — The Lengthening Shadow of Love

All 7 questions

Read Chapter 4 of Sacred Marriage. Key passages: 1 Corinthians 13:4–8; John 15:13; Romans 5:8.

1.Thomas draws a sharp distinction between the love that is an emotion and the love that is an act of the will. How does that distinction change the way you think about "falling out of love" — a phrase our culture takes very seriously?

2.He argues that learning to love a real, flawed, sometimes difficult person is one of the primary ways God teaches us to love him and others well. How has loving your spouse taught you something about the nature of love that you couldn't have learned any other way?

+ 5 more questions

Week 6: Chapter 5 — Falling Forward

All 7 questions

Read Chapter 5 of Sacred Marriage. Key passages: Matthew 18:21–35; Colossians 3:12–14; Luke 23:34.

1.Thomas describes marriage as a place where we fall — into sin, into selfishness, into failure — repeatedly, and argues that the question is not whether we will fall but whether we will fall forward into grace. What does "falling forward" mean to you in the context of your marriage?

2.He unpacks the parable of the unmerciful servant in Matthew 18 as a picture of what happens when someone who has been forgiven an enormous debt refuses to forgive a small one. Where in your marriage have you been that unmerciful servant — holding onto a small offense after God has forgiven you an infinite one?

+ 5 more questions

Week 7: Chapter 6 — Sexual Saints

All 7 questions

Read Chapter 6 of Sacred Marriage. Key passages: Song of Solomon 1–2; 1 Corinthians 7:3–5; Hebrews 13:4.

1.Thomas pushes back against both a gnostic suspicion of physical pleasure and a purely therapeutic view of sex. In his view, what is the sacred purpose of marital sexuality? How does that framing differ from what you have heard most often — in church or in culture?

2.He draws extensively from the Song of Solomon to argue that erotic love between husband and wife is not merely permitted by God but celebrated by him. Does it change anything for you to read the Song of Solomon as inspired Scripture that includes frank celebration of physical desire? Why or why not?

+ 5 more questions

Week 8: Chapter 7 — Polluted Rivers

All 7 questions

Read Chapter 7 of Sacred Marriage. Key passages: Proverbs 5:15–18; Matthew 5:27–28; 1 Thessalonians 4:3–5.

1.Thomas uses the image of a river to describe marital sexuality — clean, life-giving, and bounded — and a polluted river to describe what happens when lust or unfaithfulness enters. What specific things "pollute the river" in the context he describes, and why does he treat them with such seriousness?

2.He addresses lust not merely as a moral failure but as a spiritual one — an act that fractures the soul's capacity for the very intimacy it craves. How does that framing help you understand why Jesus treated lust so seriously in Matthew 5?

+ 5 more questions

Week 9: Chapter 8 — Sacred History

All 7 questions

Read Chapter 8 of Sacred Marriage. Key passages: Deuteronomy 7:9; Psalm 78:4–7; Malachi 2:14–15.

1.Thomas describes the "sacred history" a couple builds as a unique resource — memories, inside language, shared suffering, and shared joy that no one else has. How would you describe the sacred history you and your spouse have built together so far?

2.He makes the case that long-term commitment is what makes this history possible — that the depth only comes with time, and that every time we recommit to staying in the marriage, we are investing in its future richness. How does this perspective on commitment as investment change how you think about difficult seasons?

+ 5 more questions

Week 10: Chapter 9 — Choosing to Love

All 7 questions

Read Chapter 9 of Sacred Marriage. Key passages: Deuteronomy 30:19–20; Joshua 24:15; John 13:34–35.

1.Thomas argues that the daily, unglamorous choices of marriage — getting up when a child cries, biting your tongue during an argument, choosing to ask how your spouse's day was when you are exhausted — are the actual substance of love. How does that reframe what love looks like in your marriage on an ordinary Tuesday?

2.He challenges the cultural narrative that love is something that "happens to" us — something we fall into and can fall out of — and argues instead that love is something we choose and keep choosing. Where in your own thinking do you still operate from the "falling in love" model rather than the "choosing to love" model?

+ 5 more questions

Week 11: Chapter 10 — Marriage: A Call to Love and Serve God

All 7 questions

Read Chapter 10 of Sacred Marriage. Key passages: Matthew 22:36–40; Galatians 2:20; 2 Corinthians 5:15.

1.Thomas argues that the highest purpose of marriage is not even a good marriage — it is using the marriage as a context for loving and glorifying God. How does that claim sit with you? Does it feel liberating or threatening — and why?

2.He draws on Paul's declaration in Galatians 2:20 — "I no longer live, but Christ lives in me" — to argue that a Christian's primary identity is not "spouse" but "servant of Christ," and that this actually makes us better spouses. How does keeping your primary allegiance to God rather than to your marriage change how you approach the marriage?

+ 5 more questions

Week 12: Epilogue — Building a Marriage That Lasts

All 7 questions

Read the Epilogue of Sacred Marriage. Key passages: Revelation 19:6–9; 1 Corinthians 15:58; Philippians 1:6.

1.Thomas ends with the image from Revelation of the Marriage Supper of the Lamb — the ultimate wedding toward which all earthly marriages are pointing. How does that eschatological horizon change how you think about the daily work of your marriage?

2.He argues that the best reason to persevere in a difficult marriage is not that it will eventually become easy, but that God is not finished with what he is doing in it and through it. Where do you most need to hold onto that hope right now?

+ 5 more questions

Week 13: Review & Reflection — The Sacred Journey

All 8 questions

Review your notes from Sacred Marriage and any journal entries from the past twelve weeks.

1.Of all the chapters and themes in Sacred Marriage, which one hit you hardest or changed your thinking most significantly? What was it about that chapter that landed so deeply?

2.Thomas's central thesis — that God designed marriage to make us holy more than happy — was likely either startling or confirming when you first read it. Where do you stand on that thesis now, at the end of the book? Has your view changed?

A note from the founder: I'm Josh, and I built this because most Christian books don't come with study materials — leaving volunteer leaders to build discussion questions from scratch on a Saturday night. That shouldn't be the default. If anything about your guide isn't right, reply to your order email and it comes straight to me.
