What if God designed marriage to make us holy more than to make us happy?

Marriage: a Call to Holiness More Than Happiness

• Marriage isn’t primarily designed to make you happy; it is designed to make you holy.
• God uses the challenges, disappointments, and sacrifices in marriage to expose our weaknesses and shape our character.
• Romantic love is too shallow to sustain a lifelong union—mature love must stretch, grow, and survive seasons where feelings fluctuate.
• Marriage constantly reveals the selfish parts of us that we would never confront on our own.
• A “holy” marriage looks beyond personal comfort and asks, “How is this shaping me into Christlikeness?”
• Difficulties in marriage don’t mean you married the wrong person—they tell you’re being invited into spiritual transformation.
• Real fulfillment in marriage flows from God, not from your spouse. Your spouse can bless you, but cannot be God to you.
• When marriage is approached as a spiritual discipline, even painful moments become growth opportunities.
• Happiness in marriage becomes deeper and more stable when holiness becomes the pursuit.
• The ultimate purpose of marriage is to reflect Christ’s love and develop a heart that is more like His.

Your spouse is not just your partner but God’s tool for your transformation.

Finding God in Marriage

• Marriage is designed not just to make you happy, but to help you find God in your daily interactions.
• Your spouse becomes a mirror, revealing your heart, your weaknesses, and areas where God wants to transform you.
• Marriage teaches deep spiritual truths—love, sacrifice, forgiveness, patience, and grace in real, practical ways.
• God uses marriage as a divine tool to shape your character and grow Christlikeness.
• Conflict, disappointments, and differences become opportunities to experience God’s refining work.
• True intimacy comes when, as couples, you surrender your expectations and allow God to be at the center of your relationship.
• Spiritual maturity grows when, as couples, you learn to serve each other selflessly.
• Marriage points you toward the ultimate relationship—union with Christ, which earthly marriage only reflects.

Loving my spouse when it’s difficult may be the most spiritual thing I do all day.

Learning to Love

• Love in marriage is not primarily a feeling but a daily choice shaped by character and commitment. 
• God uses marriage as a training ground to teach us how to love imperfect people, just as He loves us in our imperfections. 
• True love requires patience, sacrifice, forgiveness, and intentional pursuit, even when emotions fluctuate. 
• Marriage exposes selfishness and forces spouses to practice selfless, Christlike love that prefers the other person. 
• Conflict, differences, and frustrations are opportunities to grow in maturity, not excuses to withdraw from love. 
• Loving your spouse deeply helps you love God better, because love for God is proven in how you treat people—especially your spouse.

Marriages rarely die from lack of love; they wither from lack of daily, intentional honor.

Holy Honor in Marriage

• Honor is one of the most essential and spiritual expressions in marriage, rooted deeply in Scripture. 
• Many marriages suffer not from lack of love but from lack of honor—the day-to-day respect that nourishes intimacy. 
• True honor begins when we choose to see our spouse the way God sees them—bearers of His image, worthy of respect regardless of performance. 
• Honor in marriage is less about emotion and more about conscious commitment—a deliberate decision to treat your spouse with dignity. 
• Dishonor usually grows subtly: sarcasm, criticism, dismissiveness, and taking one another for granted. 
• God uses marriage to train believers to cultivate godly character—honor softens the heart and makes room for spiritual growth. 
• When we honor our spouse, we honor God Himself, because we are respecting someone He has placed in our care. 
• Honor helps us rise above selfishness, pride, and entitlement—habits that easily corrode relationships. 
• Choosing honor even when the spouse “doesn’t deserve it” is part of the spiritual discipline that marriage creates. 
• Ultimately, honor transforms the atmosphere of the home, opening the door to peace, unity, and deeper spiritual connection. 

True intimacy is born not from avoiding struggles but from growing through them together.

The Soul’s Embrace

• Marriage is designed to press two very different people into a deep relational and spiritual connection — a “soul embrace” that mirrors Christ’s union with the Church.
• True intimacy requires vulnerability, honesty, sacrifice, and a willingness to let God shape your character through marital challenges.
• A deep connection cannot happen without intentional effort: listening well, forgiving quickly, and choosing love even when emotions fade.
• The soul’s embrace is not merely emotional closeness; it is a covenantal, spiritual bond formed through humility, repentance, and daily choosing unity.
• Conflicts and differences become opportunities for spiritual growth when handled with grace and a heart open to God.
• Marriage calls us to put the other person first — a practice that shapes us into Christlike people.
• The deepest marital intimacy comes from two spiritually mature people pursuing God, not merely pursuing each other.

Marriage doesn’t make us arrogant; it exposes the arrogance already within us.

The Cleansing of Marriage

• Marriage exposes selfishness, impatience, pride, and hidden weaknesses—not to shame you, but to cleanse and mature us.
• God uses marital conflict and tension as a refining fire to shape our character, not as proof that we married the wrong person.
• The goal of marriage is not comfort but transformation—God purifies us through the daily friction of living closely with another imperfect person.
• Instead of blaming your spouse for your reactions, marriage invites you to ask: What is God trying to change in me through this?
• Holiness develops when spouses choose humility, confession, forgiveness, and repentance in their interactions.
• Marriage becomes a spiritual discipline when we allow its challenges to break our selfishness and build Christlike love.
• Accepting your spouse’s faults with grace mirrors God’s acceptance of you and creates an atmosphere where both partners grow.
• Marriage becomes cleansing when, as spouses, you stop defending your egos and start seeking transformation through honest reflection.

Don’t abort your history with the spouse whom God has called you to love.

The Spiritual Discipline of Perseverance

• Marriage creates a sacred shared history, a story two people build together over time—full of joys, pains, victories, failures, and seasons of silence. 
• Past wounds can produce fear in marriage, especially the fear that conflict will lead to abandonment. 
• Perseverance is the glue of sacred history—the same perseverance God demonstrates in His covenant with Israel, despite their repeated failures. 
• The difficult seasons—arguments, disappointments, silence, routine—are not signs that the marriage is failing, but opportunities to grow in Christlike steadfastness. 
• Marriage allows you to experience God’s heart: His joy, His grief, His long-suffering love toward His people. 
• Focusing on the story you are building together strengthens your marriage and protects it from division. Remembering your shared journey brings perspective and renewed commitment. 
• Just like Israel’s long walk with God, marriage includes exciting moments, dull stretches, painful seasons, and silent periods, but the commitment must remain. 
• The purpose is to learn to walk faithfully, even when emotions fluctuate, trusting that perseverance forms deep spiritual maturity.

It’s how we respond to sin that will determine whether our marriages become a casualty statistic or a crown of success.

Embracing Difficulty to Build Character

• Marriage is one of the strongest tools God uses to confront our selfishness and shape our character.
• Difficult seasons in marriage are not proof that something is wrong; they are part of the journey God uses to refine us.
• The struggles, arguments, disappointments, and misunderstandings in marriage reveal what is inside us and show how much we still need grace.
• Hardship pushes us either toward growth and humility or toward denial, resentment, and spiritual decline.
• Marriage mirrors God’s relationship with Israel—filled with joy, pain, silence, betrayal, and restoration.
• God uses marital struggle to teach perseverance, faithfulness, forgiveness, and spiritual maturity.
• Instead of escaping challenges, believers are called to see difficulty as sacred—an invitation from God to grow.
• The decision to persevere when marriage is tough forms the backbone of Christlike character.

Forgiveness keeps a marriage moving forward; without it, our hearts slowly close.

Marriage Teaches Us to Forgive

• Marriage repeatedly confronts spouses with opportunities to practice forgiveness, just as God forgives us.
• Every marriage will face hurt, disappointment, or betrayal at some level; the question is how we respond.
• Forgiveness is not denial—it is a deliberate choice to release the offense and move toward healing.
• Marriage becomes a spiritual classroom where we learn grace, mercy, humility, and emotional maturity.
• Unforgiveness chokes intimacy; forgiveness frees both partners and deepens marital unity.
• Spouses grow closer to God when they forgive because forgiveness reflects the heart of Christ.
• Choosing to forgive aligns you with the gospel, which is built on reconciliation and restoration.
• The discipline of forgiveness forms Christ’s character in you, helping you “fall forward” instead of collapsing under relational strain.

God is always worthy of being obeyed and served—so regardless of how your spouse treats you, you are called to respond as a servant.

Marriage Builds in You a Servant’s Heart

• Marriage is a spiritual training ground where God forms a servant’s heart in us. 
• Christian marriage reflects Christ’s example in Philippians 2 — laying aside rights to serve another. 
• True Christian spirituality is not just about beliefs but living in humility, considering your spouse’s needs above your own.
• Marriage forces you to confront selfishness, entitlement, and the desire to control — turning you instead toward sacrifice and service.
• Serving your spouse isn’t optional; it is part of serving God, because God is always “worthy,” even if your spouse is not perfect. 
• A servant heart requires the right spirit—not serving to dominate, impress, or earn superiority, but serving willingly and joyfully. 
• Service includes receiving help from your spouse and allowing them to serve as well.
• Money and time quickly reveal a person’s heart—many conflicts arise from power struggles, not actual needs. True service means surrendering control. 
• Marriage is a daily “paschal mystery” — dying to selfish desires and rising again to love, courage, compromise, and service. 
• A Christian marriage proposal should be an offer (“Here is what I want to give”) — not a demand (“Here is what I want you to do for me”).
• Serving your spouse—especially when they don’t seem to “deserve” it—becomes a powerful act of worship to God. 
• True service brings inner joy, spiritual strength, and freedom from bitterness and self-absorption. 

Sex exposes us—our fears, our selfishness, our insecurities; it becomes a mirror revealing who we truly are.

Marital Sexuality Provides Spiritual Insights on Growth and Character Development

• Sex is sacred, not merely physical—the author argues that marital sexuality is spiritually significant, shaped by God to teach intimacy, partnership, joy, and self-giving.
• Sex exposes the heart. In marriage, sexual struggles often reveal deeper relational or spiritual issues such as selfishness, fear, insecurity, or emotional distance.
• Scripture presents sex within marriage as holy, joyful, and purposeful, not shameful or merely functional.
• Sex requires mutual love and service — A fulfilling sexual relationship grows through patience, communication, vulnerability, and sincere desire to please the other.
• Gratitude and purity protect the marriage bed — Seeing your spouse as God’s gift promotes thankfulness, prevents comparison, and strengthens commitment.
• Sexual intimacy is a discipline — Just like prayer or service, sex becomes a place to practice humility, generosity, and emotional connection.
• Spiritual growth through sexuality — Healthy sexuality teaches self-control, compassion, forgiveness, sacrifice, and the beauty of shared pleasure.
• The enemy attacks sexual unity — Thomas highlights how spiritual warfare often targets sexual intimacy to disrupt unity, joy, and purpose in marriage.
• Sex can be a form of worship — When approached with purity, love, and gratitude, marital sexuality reflects God’s creativity, generosity, and delight.

God made humankind to need more than himself… the staggering humility of God is incomprehensible.

Marriage Brings Awareness of God’s Presence

• Marriage trains us to recognize God’s presence in daily life, not just in spiritual moments.
• Spouses often become channels of God’s grace, comfort, correction, and encouragement.
• God uses the ordinary routines of marriage to teach patience, attentiveness, humility, and love.
• Learning to be present with your spouse helps you learn to be present with God—the same spiritual muscles are required.
• Marriage exposes our tendency to chase spiritual highs while ignoring God in the mundane.
• Deep companionship, emotional intimacy, and shared life create a rhythm where God can be encountered in relationship, not isolation.
• True spiritual maturity is found in seeing God everywhere, including in the imperfections and needs of your spouse.
• Marriage reminds us that humans were created with both a need for God and a need for each other, and one doesn’t replace the other.
• Serving, listening, forgiving, and loving your spouse trains your heart to be more sensitive to God’s voice.
• As couples grow, their home becomes a sanctuary of God’s presence—a spiritual atmosphere shaped by unity, love, and peace.

Christian marriage is marked by discipline and self-denial… Christianity does not depreciate marriage; it sanctifies it.

Marriage Can Develop Your Spiritual Calling, Mission, and Purpose 

• Marriage is not only for companionship—it is a spiritual partnership designed to help couples pursue a shared mission under God.
• God uses marriage to shape two people into one purposeful team, aligning their strengths, weaknesses, and experiences for kingdom impact.
• A Christian couple is called to follow Christ together, embracing sacrifice, obedience, and service in pursuit of God’s will.
• Marriage becomes a place where spouses discern God’s purpose, support each other’s calling, and grow in spiritual maturity.
• The journey of marriage trains couples to live with intentionality, courage, and surrender to God’s will—just like the saints who lived sacrificially for Christ.
• True marital mission means asking not “How can this marriage serve me?” but “How can we together serve God?”
• Spouses are companions not only for life on earth but also as co-laborers in their spiritual destiny.
• Marriage shapes your character so that, as a couple, you can better fulfill your heavenly purpose—often through daily discipline, love, perseverance, and obedience.
