12 Bible Verses on Marrying an Unsaved Person

To the married I give this command (not I, but the Lord): A wife must not separate from her husband. But if she does, she must remain unmarried or else be reconciled to her husband. And a husband must not divorce his wife. To the rest I say this (I, not the Lord): If a brother has an unbelieving wife and she is willing to live with him, he must not divorce her. And if a woman has an unbelieving husband and he is willing to live with her, she must not divorce him. For the unbelieving husband is sanctified through his believing wife, and the unbelieving wife is sanctified through her believing husband. Otherwise your children would be unclean, but now they are holy. But if the unbeliever leaves, let him go. The believing brother or sister is not bound in such cases. God has called you to live in peace. How do you know, wife, whether you will save your husband? Or how do you know, husband, whether you will save your wife? Regardless, each one should lead the life that the Lord has assigned to him and to which God has called him. This is what I prescribe in all the churches.

Do not be unequally yoked with unbelievers. For what partnership can righteousness have with wickedness? Or what fellowship does light have with darkness?

But if the unbeliever leaves, let him go. The believing brother or sister is not bound in such cases. God has called you to live in peace.

Now for the matters you wrote about: It is good to abstain from sexual relations. But because there is so much sexual immorality, each man should have his own wife, and each woman her own husband. The husband should fulfill his marital duty to his wife, and likewise the wife to her husband. The wife does not have authority over her own body, but the husband. Likewise the husband does not have authority over his own body, but the wife. Do not deprive each other, except by mutual consent and for a time, so you may devote yourselves to prayer. Then come together again, so that Satan will not tempt you through your lack of self-control. I say this as a concession, not as a command. I wish that all men were as I am. But each man has his own gift from God; one has this gift, another has that. Now to the unmarried and widows I say this: It is good for them to remain unmarried, as I am. But if they cannot control themselves, let them marry. For it is better to marry than to burn with passion. To the married I give this command (not I, but the Lord): A wife must not separate from her husband. But if she does, she must remain unmarried or else be reconciled to her husband. And a husband must not divorce his wife. To the rest I say this (I, not the Lord): If a brother has an unbelieving wife and she is willing to live with him, he must not divorce her. And if a woman has an unbelieving husband and he is willing to live with her, she must not divorce him. For the unbelieving husband is sanctified through his believing wife, and the unbelieving wife is sanctified through her believing husband. Otherwise your children would be unclean, but now they are holy. But if the unbeliever leaves, let him go. The believing brother or sister is not bound in such cases. God has called you to live in peace. How do you know, wife, whether you will save your husband? Or how do you know, husband, whether you will save your wife? Regardless, each one should lead the life that the Lord has assigned to him and to which God has called him. This is what I prescribe in all the churches. Was a man already circumcised when he was called? He should not become uncircumcised. Was a man still uncircumcised when called? He should not be circumcised. Circumcision is nothing and uncircumcision is nothing. Keeping God’s commandments is what counts. Each one should remain in the situation he was in when he was called. Were you a slave when you were called? Do not let it concern you—but if you can gain your freedom, take the opportunity. For he who was a slave when he was called by the Lord is the Lord’s freedman. Conversely, he who was a free man when he was called is Christ’s slave. You were bought at a price; do not become slaves of men. Brothers, each one should remain in the situation he was in when God called him. Now about virgins, I have no command from the Lord, but I give a judgment as one who by the Lord’s mercy is trustworthy. Because of the present crisis, I think it is good for a man to remain as he is. Are you committed to a wife? Do not seek to be released. Are you free of commitment? Do not look for a wife. But if you do marry, you have not sinned. And if a virgin marries, she has not sinned. But those who marry will face troubles in this life, and I want to spare you this. What I am saying, brothers, is that the time is short. From now on those who have wives should live as if they had none; those who weep, as if they did not; those who are joyful, as if they were not; those who make a purchase, as if they had nothing; and those who use the things of this world, as if not dependent on them. For this world in its present form is passing away. I want you to be free from concern. The unmarried man is concerned about the work of the Lord, how he can please the Lord. But the married man is concerned about the affairs of this world, how he can please his wife, and his interests are divided. The unmarried woman or virgin is concerned about the work of the Lord, how she can be holy in both body and spirit. But the married woman is concerned about the affairs of this world, how she can please her husband. I am saying this for your own good, not to restrict you, but in order to promote proper decorum and undivided devotion to the Lord. However, if someone thinks he is acting inappropriately toward his betrothed, and if she is beyond her youth and they ought to marry, let him do as he wishes; he is not sinning; they should get married. But the man who is firmly established in his heart and under no constraint, with control over his will and resolve in his heart not to marry the virgin, he will do well. So then, he who marries the virgin does well, but he who does not marry her does even better. A wife is bound to her husband as long as he lives. But if her husband dies, she is free to marry anyone she wishes, as long as he belongs to the Lord. In my judgment, however, she is happier if she remains as she is. And I think that I too have the Spirit of God.

A wife is bound to her husband as long as he lives. But if her husband dies, she is free to marry anyone she wishes, as long as he belongs to the Lord.

But I tell you that anyone who divorces his wife, except for sexual immorality, brings adultery upon her. And he who marries a divorced woman commits adultery.

Husbands, love your wives, just as Christ loved the church and gave Himself up for her

Do not be unequally yoked with unbelievers. For what partnership can righteousness have with wickedness? Or what fellowship does light have with darkness? What harmony is there between Christ and Belial? Or what does a believer have in common with an unbeliever? What agreement can exist between the temple of God and idols? For we are the temple of the living God. As God has said: “I will dwell with them and walk among them, and I will be their God, and they will be My people.” “Therefore come out from among them and be separate, says the Lord. Touch no unclean thing, and I will receive you.” And: “I will be a Father to you, and you will be My sons and daughters, says the Lord Almighty.”

Do you not know, brothers (for I am speaking to those who know the law), that the law has authority over a man only as long as he lives? For instance, a married woman is bound by law to her husband as long as he lives. But if her husband dies, she is released from the law of marriage. So then, if she is joined to another man while her husband is still alive, she is called an adulteress; but if her husband dies, she is free from that law and is not an adulteress, even if she marries another man. Therefore, my brothers, you also died to the law through the body of Christ, that you might belong to another, to Him who was raised from the dead, in order that we might bear fruit to God. For when we lived according to the flesh, the sinful passions aroused by the law were at work in our bodies, bearing fruit for death. But now, having died to what bound us, we have been released from the law, so that we serve in the new way of the Spirit, and not in the old way of the written code. What then shall we say? Is the law sin? Certainly not! Indeed, I would not have been mindful of sin if not for the law. For I would not have been aware of coveting if the law had not said, “Do not covet.” But sin, seizing its opportunity through the commandment, produced in me every kind of covetous desire. For apart from the law, sin is dead. Once I was alive apart from the law; but when the commandment came, sin sprang to life and I died. So I discovered that the very commandment that was meant to bring life actually brought death. For sin, seizing its opportunity through the commandment, deceived me and through the commandment put me to death. So then, the law is holy, and the commandment is holy, righteous, and good. Did that which is good, then, become death to me? Certainly not! But in order that sin might be exposed as sin, it produced death in me through what was good, so that through the commandment sin might become utterly sinful. We know that the law is spiritual; but I am unspiritual, sold as a slave to sin. I do not understand what I do. For what I want to do, I do not do. But what I hate, I do. And if I do what I do not want to do, I admit that the law is good. In that case, it is no longer I who do it, but it is sin living in me that does it. I know that nothing good lives in me, that is, in my flesh; for I have the desire to do what is good, but I cannot carry it out. For I do not do the good I want to do. Instead, I keep on doing the evil I do not want to do. And if I do what I do not want, it is no longer I who do it, but it is sin living in me that does it. So this is the principle I have discovered: When I want to do good, evil is right there with me. For in my inner being I delight in God’s law. But I see another law at work in my body, warring against the law of my mind and holding me captive to the law of sin that dwells within me. What a wretched man I am! Who will rescue me from this body of death? Thanks be to God, through Jesus Christ our Lord! So then, with my mind I serve the law of God, but with my flesh I serve the law of sin.

So He told them, “Whoever divorces his wife and marries another woman commits adultery against her. And if a woman divorces her husband and marries another man, she commits adultery.”

Husbands, in the same way, treat your wives with consideration as a delicate vessel, and with honor as fellow heirs of the gracious gift of life, so that your prayers will not be hindered.

For this reason a man will leave his father and mother and be united to his wife, and they will become one flesh.
