Building a Marriage That Lasts: Seven Biblical Principles Every Couple Needs

Imagine two believers, both active in church, both sincere in their faith, and yet their marriage is quietly unravelling. There is no adultery, no violence — just distance, unresolved bitterness, and two people living as strangers under one roof. This is not a rare story in Nigerian Christian homes. The pressure of economic hardship, extended family interference, cultural expectations, and unspoken personal wounds can erode even the most promising union. The question is not whether marriage is hard — it is — but whether we are building it on the right foundation. Scripture does not leave us guessing. God, who instituted marriage, has provided clear, timeless principles for making it thrive.

The first and most foundational principle is that marriage is a covenant, not a contract. When God brought Eve to Adam in Genesis 2:24, He declared, ‘Therefore shall a man leave his father and his mother, and shall cleave unto his wife: and they shall be one flesh.’ The word ‘cleave’ in Hebrew is *dabaq* — to cling, to be glued, to pursue with urgency. This is not the language of a business arrangement. It is the language of sacred commitment. A contract says, ‘I will perform as long as the terms are favourable.’ A covenant says, ‘I am yours regardless.’ Many Nigerian marriages are quietly operating as contracts — I will stay faithful as long as you provide, as long as you behave, as long as things are comfortable. But God’s design is deeper. Until couples understand that their marriage is a divine covenant witnessed by God Himself, they will always be one bad season away from collapse.

The second principle is sacrificial love — not romantic feeling, but deliberate, costly devotion. Ephesians 5:25 commands plainly, ‘Husbands, love your wives, even as Christ also loved the church, and gave himself for it.’ This verse does not say love your wives when they are loveable. It does not say love them after they have submitted. Christ gave Himself for the church while she was yet unworthy. The same passage instructs wives in verse 22 to submit to their husbands ‘as unto the Lord.’ Both commands require dying to self. In a culture where the husband often sees himself as lord and the wife often uses submission selectively, Scripture calls both parties to a mutual, sacrificial yielding. The husband leads by serving. The wife honours by trusting. When both operate in their God-given roles, the marriage becomes a living picture of Christ and the church.

Third, communication rooted in truth and grace is non-negotiable. Ephesians 4:15 urges believers to be ‘speaking the truth in love.’ Many Nigerian couples either go silent — the husband who refuses to talk, the wife who bottles everything — or they speak truth without love, cutting each other with words. Neither is biblical. Marriage requires the courage to say what is real and the discipline to say it with tenderness. This means discussing finances openly, naming unmet needs, addressing grievances before they calcify into resentment, and refusing to let the sun go down on unresolved anger, as Ephesians 4:26 instructs. Silence in marriage is not peace. It is a slow poison.

Fourth, forgiveness must be a regular practice, not an occasional emergency measure. Colossians 3:13 instructs, ‘Forbearing one another, and forgiving one another, if any man have a quarrel against any: even as Christ forgave you, so also do ye.’ Two imperfect people living in one house will wound each other. The question is not whether offence will come — it will — but what you will do with it. Forgiveness is not weakness. It is not pretending the wound never happened. It is a decision, made in obedience to Christ, to release the debt. Couples who refuse to forgive carry their past into their future, and the weight eventually breaks the marriage.

Fifth, prayer together is not optional. It is spiritual oxygen for a Christian marriage. When Jesus taught in Matthew 18:19 that ‘if two of you shall agree on earth as touching any thing that they shall ask, it shall be done for them of my Father which is in heaven,’ He described a covenant power available to two people in agreement. There is no more intimate agreement than that between husband and wife. Couples who pray together regularly — not just Sunday services, but at home, over their children, over their finances, over their conflicts — build a spiritual intimacy that no external pressure can easily destroy.

Sixth, guard the marriage from outside voices that do not belong inside it. The Genesis 2:24 command to ‘leave’ father and mother is not merely geographical. It is relational and decisional. In Nigerian society, where extended family involvement is deeply cultural, many marriages suffer because a mother-in-law’s opinion outweighs a spouse’s, or siblings are consulted before a partner is. Honour your family, yes. But your primary earthly loyalty now belongs to your spouse. What is spoken in your home should not be carried out to relatives who will use it as ammunition.

Seventh and finally, keep Christ at the centre — genuinely, not ceremonially. Ecclesiastes 4:12 says, ‘A threefold cord is not quickly broken.’ A marriage of two people without God is a cord of two strands — manageable in calm weather, fragile in a storm. A marriage where both partners are actively, individually pursuing Christ brings a third strand into the union that can hold when human strength fails.

If your marriage is struggling, do not pretend it is not. Seek godly counsel. Return to Scripture. Repent where necessary. Begin again. If your marriage is thriving, protect it with intention. The enemy is not passive about Christian homes. Neither should you be. Take one principle from this article this week and begin applying it. Your marriage is worth fighting for — not because it is easy, but because God designed it to reflect His glory.
