Marriage is one of the most important decisions a person can make.
It’s a lifelong commitment to love, support, and grow together with another person.
For Christians, marriage is more than just a legal bond; it’s a sacred union designed by God.
But what happens when a Christian is considering marrying someone who doesn’t share their faith?
What does the Bible say about marrying a non-believer, and how should Christians navigate this challenging situation?
In this article, we will explore the Bible’s teachings on marriage, faith, and relationships, and provide insight into what it says about marrying someone who does not believe in Jesus Christ.
Marriage: A Sacred Covenant
The Bible views marriage as a sacred covenant, a union that reflects the relationship between Christ and the church.
In Ephesians 5:25, Paul writes, “Husbands, love your wives, just as Christ loved the church and gave himself up for her.”
This passage emphasizes the importance of sacrificial love and commitment in marriage.
For Christians, marriage isn’t just about two people being together—it’s a partnership where both individuals help each other grow in faith and live out God’s purpose for their lives.
Marriage is designed to be a relationship where both partners seek to honor God in their lives and in their relationship.
Because of this, the Bible encourages Christians to marry someone who shares their faith and values.
When both partners are committed to following Jesus, their marriage can be a strong reflection of God’s love and purpose.
Being “Unequally Yoked”
One of the most direct teachings about marrying a non-believer comes from 2 Corinthians 6:14-15, where Paul writes, “Do not be yoked together with unbelievers.
For what do righteousness and wickedness have in common?
Or what fellowship can light have with darkness?
What harmony is there between Christ and Belial?
Or what does a believer have in common with an unbeliever?”
In this passage, Paul uses the metaphor of being “yoked” to describe the close relationship between believers and non-believers.
A yoke is a wooden beam used to connect two animals, such as oxen, so they can work together to pull a load.
If the two animals are unequally yoked, meaning they are of different sizes or strengths, they won’t be able to work together effectively.
In the same way, Paul warns that if a Christian is “yoked” or closely connected with a non-believer, it can create challenges and tension in their relationship.
Their priorities, values, and spiritual goals may be at odds with each other, making it difficult to grow together in faith.
Spiritual Conflict in Marriage
Marrying a non-believer can lead to spiritual conflict within the marriage.
While love and attraction may initially bring two people together, their differences in belief can create significant challenges over time.
For example, a Christian may want to prioritize their relationship with God, attend church regularly, and raise their children in the Christian faith, while a non-believing spouse may not share those desires.
This can lead to tension and disagreement, especially when it comes to making important decisions about family life and faith.
In Amos 3:3, it says, “Do two walk together unless they have agreed to do so?”
This verse speaks to the importance of unity in a relationship.
When two people are walking in different spiritual directions, it can be difficult to maintain harmony and a shared vision for the future.
While it’s possible for a Christian to have a loving and successful marriage with a non-believer, the spiritual differences can create obstacles that make it harder to grow together in faith and purpose.
The Importance of Shared Faith
The Bible emphasizes the importance of shared faith in marriage because it strengthens the foundation of the relationship.
In 1 Corinthians 7:39, Paul gives advice to widows, saying, “A woman is bound to her husband as long as he lives.
But if her husband dies, she is free to marry anyone she wishes, but he must belong to the Lord.”
This instruction highlights that Christians are encouraged to marry within the faith.
When both partners share a relationship with Christ, they can support one another spiritually, pray together, and encourage each other in their walk with God.
This spiritual connection deepens the bond between husband and wife and allows them to face challenges together with a shared sense of purpose.
A marriage built on a shared faith has the potential to thrive because both partners are committed to living out biblical principles and seeking God’s guidance in their relationship.
In contrast, when one partner does not believe in God or share the same spiritual values, it can create a gap that makes it harder to build a solid foundation.
What If You’re Already Married to a Non-Believer?
While the Bible encourages believers to marry within the faith, it also addresses situations where a Christian is already married to a non-believer.
In 1 Corinthians 7:12-14, Paul writes, “If any brother has a wife who is not a believer and she is willing to live with him, he must not divorce her.
And if a woman has a husband who is not a believer and he is willing to live with her, she must not divorce him.
For the unbelieving husband has been sanctified through his wife, and the unbelieving wife has been sanctified through her believing husband.”
This passage offers guidance for Christians who are already married to a non-believer.
Paul encourages them to stay in the marriage as long as the non-believing spouse is willing to remain in the relationship.
He explains that the Christian spouse has a positive influence on the non-believer, and their presence can bring blessings to the family.
In these cases, the Christian is called to live out their faith in a way that reflects God’s love and grace, even if their spouse does not share the same beliefs.
The hope is that through the Christian’s example, the non-believing spouse may come to faith in Christ.
In 1 Peter 3:1-2, Peter echoes this sentiment, writing, “Wives, in the same way submit yourselves to your own husbands so that, 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.”
Challenges of Marrying a Non-Believer
While it is possible to have a successful marriage with a non-believer, the Bible acknowledges that there are unique challenges that come with this decision.
One of the main challenges is the potential for differing priorities and values.
When one spouse is focused on growing in their relationship with God and the other is not, it can create a sense of division within the marriage.
For example, the Christian spouse may feel called to serve in the church, attend Bible studies, or prioritize prayer, while the non-believing spouse may not understand or support these commitments.
This can lead to feelings of frustration and isolation, as the Christian may feel unsupported in their spiritual journey.
Another challenge is the potential for differing views on raising children.
A Christian parent may want to teach their children about God, bring them to church, and raise them according to biblical principles, while the non-believing spouse may have different views on how to approach parenting and faith.
This can lead to conflict and confusion within the family.
In Matthew 12:25, Jesus says, “Every kingdom divided against itself will be ruined, and every city or household divided against itself will not stand.”
This verse highlights the importance of unity in a family, and how division can weaken relationships.
Wisdom and Discernment in Relationships
When it comes to relationships, the Bible encourages believers to seek wisdom and discernment.
In Proverbs 3:5-6, it says, “Trust in the Lord with all your heart and lean not on your own understanding; in all your ways submit to him, and he will make your paths straight.”
This verse reminds Christians to rely on God’s guidance when making important decisions, including who they choose to marry.
Marriage is a lifelong commitment, and it’s important to consider whether the relationship will strengthen or weaken one’s faith.
By seeking God’s wisdom and praying for His direction, Christians can make choices that align with His will and lead to a strong and healthy marriage.
In James 1:5, it says, “If any of you lacks wisdom, you should ask God, who gives generously to all without finding fault, and it will be given to you.”
Through prayer and seeking God’s counsel, Christians can approach relationships with clarity and understanding.
Showing Christ’s Love in All Relationships
While the Bible cautions against marrying a non-believer, it also calls Christians to show Christ’s love in all their relationships.
Whether married to a believer or a non-believer, Christians are called to love their spouses with patience, kindness, and humility.
In Colossians 3:14, Paul writes, “And over all these virtues put on love, which binds them all together in perfect unity.”
Even in difficult situations, love is the foundation that can help a marriage thrive.
By demonstrating Christ’s love through their actions, Christians can have a positive influence on their spouse, showing them the beauty of a relationship with God.
In 1 Corinthians 13:4-7, it says, “Love is patient, love is kind.
It does not envy, it does not boast, it is not proud.
It does not dishonor others, it is not self-seeking, it is not easily angered, it keeps no record of wrongs.
Love does not delight in evil but rejoices with the truth.
It always protects, always trusts, always hopes, always perseveres.”
This passage reminds believers that love is not conditional on shared beliefs but is an act of grace and selflessness.
Final Thoughts
The Bible offers clear guidance on the importance of shared faith in marriage, encouraging believers to marry someone who shares their commitment to Christ.
Being “unequally yoked” with a non-believer can create challenges and spiritual conflict, making it harder to grow together in faith and purpose.
However, the Bible also offers hope and instruction for those who are already married to a non-believer, encouraging them to stay committed and to live out their faith in a way that reflects God’s love.
Ultimately, marriage is a sacred covenant designed by God, and by seeking His wisdom and guidance, Christians can build relationships that honor Him and bring lasting joy.
