Most couples do not fall out of love. They fall out of effort. Romance sustains itself early on because everything is new. Over time, what a marriage actually runs on is something more demanding and more durable than feeling: it runs on covenant.
The Bible has a great deal to say about marriage, and most of it is harder than people expect. It does not primarily offer tips for better communication, though it implies those. It offers a vision of what marriage is for and what it costs. That vision is high enough to be challenging and true enough to be worth the work.
This guide is for couples who want to study Scripture together, and for individuals who want to understand what the Bible actually teaches about marriage, whether their own is thriving, struggling, or somewhere in between.
"Place me like a seal over your heart, like a seal on your arm; for love is as strong as death, its jealousy unyielding as the grave." - Song of Solomon 8:6
Marriage as Covenant: Starting With Genesis 2
Before Ephesians, before Song of Solomon, before any specific instruction about marriage roles or practices, there is Genesis 2.
"That is why a man leaves his father and mother and is united to his wife, and they become one flesh."
Three actions are named: leaving, uniting, becoming one flesh. Jesus quotes this passage in Matthew 19 when asked about divorce, and he treats it as foundational. Paul quotes it in Ephesians 5 and in 1 Corinthians 6. It is the bedrock.
What the text establishes:
Leaving is a social act. It means the primary loyalty shifts. Before marriage, a person's defining relationships are with parents and family of origin. After marriage, the primary bond is the spouse. This is not abandonment of family. It is a reordering.
Uniting (dabaq in Hebrew) means cleaving, clinging, sticking. It is used elsewhere of Ruth's loyalty to Naomi, of Israel cleaving to God. It describes a bond that does not let go.
"One flesh" is not only about physical union, though it includes that. It is a picture of two lives so woven together that they form something new. Not two people living parallel lives under the same roof, but two people whose lives have genuinely merged.
The covenant framing matters because covenants are not contracts. A contract is conditional: I will do X if you do Y. A covenant is unconditional in its basic commitment, though it carries obligations on both sides. Marriage as covenant means the commitment precedes performance. You stay not because your spouse has earned it today but because you made a covenant.
Study question: How does understanding marriage as covenant rather than contract change the way you think about hard seasons? What would change if the commitment were the foundation rather than the outcome of feeling?
Passage 1: Ephesians 5:22-33. The Most Misread Marriage Passage in the Bible.
This passage is often quoted selectively and almost always misread, either by those who use it to justify domination or by those who avoid it entirely because it makes them uncomfortable.
Read the whole thing carefully.
Paul begins in verse 21: "Submit to one another out of reverence for Christ." The mutual submission is the frame for everything that follows. Neither the instruction to wives nor the instruction to husbands can be rightly read without it.
To wives (verse 22-24): "Wives, submit to your husbands as you do to the Lord." The submission described is voluntary, not coerced. The word hupotasso in Greek refers to a chosen ordering, the way a soldier defers to a commanding officer or a citizen to a governing body. It does not mean inferiority. It does not authorize abuse. It describes a posture of respect and trust within a specific relationship.
To husbands (verses 25-33): Paul spends three times as many words on this side of the instruction. "Husbands, love your wives, just as Christ loved the church and gave himself up for her." The love commanded is sacrificial self-giving. The model is the cross.
This is an extraordinarily high standard. Christ did not demand the church's submission before loving her. He loved her while she was still an enemy (Romans 5:8). The husband who uses this passage to demand deference while giving nothing is reading it backwards. Paul's primary word to the husband is: die for her. Give yourself up.
The final verse summarizes: "Each one of you also must love his wife as he loves himself, and the wife must respect her husband." Love and respect. Paul seems to understand that men and women often feel these differently, and he asks each partner to give what the other most needs.

Passage 2: Song of Solomon. The Bible's Love Poem.
Song of Solomon is the strangest book in the Bible for many readers. It is explicitly romantic and physical. It celebrates desire, longing, and the beauty of a beloved. It has no obvious theological statements. It is just a love poem.
That it is in the canon is itself a theological statement. The physical, emotional, and erotic dimension of marriage is not something the Bible tolerates reluctantly. It celebrated it enough to include eight chapters of it in Scripture.
What Song of Solomon shows:
The lovers in the poem pursue each other. They describe each other in elaborate and admiring terms. They speak of longing during separation and delight in reunion. The woman in the poem speaks as often and as boldly as the man. This is not a passive relationship. Both partners are active in their love.
Song of Solomon 2:16 says: "My beloved is mine and I am his." This mutual belonging is the relational posture of the whole poem. Not ownership in the controlling sense, but a mutual giving and receiving of self.
The poem also shows that desire, when it is honored and kept within its right context, is a gift rather than a problem. The church has sometimes treated physical desire as spiritually suspect. Song of Solomon simply refuses that view.
Study question: When did you last tell your spouse specifically what you admire about them? What would it look like to pursue them the way the lovers in Song of Solomon pursue each other?
Passage 3: 1 Corinthians 7 and 13. Practical Love and What It Actually Looks Like.
1 Corinthians 13 is read at weddings constantly. It is almost never read carefully.
"Love is patient, love is kind." These are not descriptions of romantic feeling. They are descriptions of chosen behavior. The Greek words are active: patience (makrothumeo) is long-suffering, bearing with someone over time. Kindness (chresteuomai) means acting generously toward someone.
"Love does not dishonor others, it is not self-seeking, it is not easily angered, it keeps no record of wrongs." Keep no record of wrongs is the phrase that should stop every married person. Keeping score, cataloguing offenses, bringing up old failures in new arguments: this is the opposite of love. Love cancels the debt rather than adding interest.
"Love bears all things, believes all things, hopes all things, endures all things." The word for "bears" (stego) means to cover, as a roof covers a house. Love protects. It does not expose or humiliate.
This chapter is not a romantic description of falling in love. It is a description of what sustained, mature love requires. Read it as a daily checklist rather than a wedding reading and it becomes much more demanding and much more useful.

Read this week’s issueA 7-Day Bible Study Plan for Marriage
Day 1: Genesis 2:18-25 Read slowly. What does "leaving" mean for your marriage? What does "one flesh" look like practically in your life together? Discuss with your spouse if studying together.
Day 2: Ephesians 5:21-33 Read the whole passage, starting at verse 21. Write down what the passage asks of you specifically, setting aside what it asks of your spouse.
Day 3: Song of Solomon 2:1-17 Read the whole chapter. What does it feel like to be pursued and celebrated? When did you last celebrate your spouse in specific terms? Write them a note this week.
Day 4: 1 Corinthians 13:4-8 Read each quality and ask honestly: how well am I living this out? Choose one quality to focus on for the rest of the week.
Day 5: Proverbs 31:10-31 and Proverbs 5:15-19 Read both. Proverbs 31 describes a capable, trusted, honored partner. Proverbs 5 calls spouses to find their delight in each other. What would it look like to honor and delight in your spouse today?
Day 6: Colossians 3:12-14 "Bear with each other and forgive one another if any of you has a grievance against someone. Forgive as the Lord forgave you." What are you bearing? What do you need to forgive?
Day 7: Ruth 1:16-17 Read Ruth's words to Naomi: "Where you go I will go, and where you stay I will stay." Though this is spoken between a daughter-in-law and mother-in-law, it is one of the most powerful expressions of covenant faithfulness in Scripture. Write your own version. What would you say to your spouse about the nature of your commitment?

A Prayer for Marriage
Lord, we did not know what we were promising on our wedding day. We were promising something larger than we understood.
Thank you that you did not leave the covenant to us alone. Thank you that the same love you showed in Christ is the pattern we are invited into, a love that stays, that gives itself up, that keeps no record of wrongs.
Where we have kept score, help us let go. Where we have withheld the love and respect the other person needs, make us generous. Where we are struggling, give us the humility to ask for help.
Remind us today that we are on the same side. We are not opponents. We are one flesh. Let us live like it.
Amen.
Frequently Asked Questions
What does "submit" mean in Ephesians 5 for wives?
The Greek word hupotasso describes a voluntary, chosen ordering, not coerced compliance. It is the same word used of Jesus submitting to his parents (Luke 2:51) and of all believers submitting to one another (Ephesians 5:21). It carries no implication of inferiority or of tolerating abuse. It describes a posture of trust and respect within a relationship defined by sacrificial love on the husband's side.
Does the Bible allow for divorce?
Jesus addresses this directly in Matthew 19:3-9. He affirms the permanence of marriage as God's design while acknowledging Moses permitted divorce because of the hardness of human hearts. He names sexual immorality as grounds. Paul adds in 1 Corinthians 7:15 that desertion by an unbelieving spouse may release the believing partner. This is a theologically complex topic. For specific situations, pastoral guidance is important.
How do we study the Bible together when we disagree on things?
Start with observation before interpretation. Read a passage together and each write down what you actually see in the text, before any application or argument. Ask "What does this say?" before "What does this mean for us?" This slows the conversation enough to actually hear each other.
What if my spouse is not interested in studying the Bible together?
1 Peter 3:1-2 addresses this situation: "If any of them do not believe the word, they may be won over without words by the behavior of their wives, when they see the purity and reverence of your lives." The primary call is to live it yourself. Invitation is good. Pressure usually backfires.
Is attraction and physical desire something the Bible affirms in marriage?
Yes. Song of Solomon is in the canon specifically because the physical and emotional dimension of marriage is holy. Proverbs 5:18-19 tells a husband to "rejoice in the wife of your youth" and be "captivated by her love." Hebrews 13:4 says "marriage should be honored by all, and the marriage bed kept pure." Physical desire within marriage is not something to be ashamed of.
