15 Bible Verses on Unmarried Sex

Marriage should be honored by all and the marriage bed kept undefiled, for God will judge the sexually immoral and adulterers.

But because there is so much sexual immorality, each man should have his own wife, and each woman her own husband.

Put to death, therefore, the components of your earthly nature: sexual immorality, impurity, lust, evil desires, and greed, which is idolatry.

Flee from sexual immorality. Every other sin a man can commit is outside his body, but he who sins sexually sins against his own body.

For of this you can be sure: No immoral, impure, or greedy person (that is, an idolater), has any inheritance in the kingdom of Christ and of God.

But I tell you that anyone who looks at a woman to lust after her has already committed adultery with her in his heart.

But among you, as is proper among the saints, there must not be even a hint of sexual immorality, or of any kind of impurity, or of greed.

Do you not know that the wicked will not inherit the kingdom of God? Do not be deceived: Neither the sexually immoral, nor idolaters, nor adulterers, nor men who submit to or perform homosexual acts, nor thieves, nor the greedy, nor drunkards, nor verbal abusers, nor swindlers, will inherit the kingdom of God.

The acts of the flesh are obvious: sexual immorality, impurity, and debauchery; idolatry and sorcery; hatred, discord, jealousy, and rage; rivalries, divisions, factions, and envy; drunkenness, orgies, and the like. I warn you, as I did before, that those who practice such things will not inherit the kingdom of God.

I am afraid that when I come again, my God will humble me before you, and I will be grieved over many who have sinned earlier and have not repented of their acts of impurity, sexual immorality, and debauchery.

For it is God’s will that you should be holy: You must abstain from sexual immorality;

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.

“Food for the stomach and the stomach for food,” but God will destroy them both. The body is not intended for sexual immorality, but for the Lord, and the Lord for the body. By His power God raised the Lord from the dead, and He will raise us also. Do you not know that your bodies are members of Christ? Shall I then take the members of Christ and unite them with a prostitute? Never! Or don’t you know that he who unites himself with a prostitute is one with her in body? For it is said, “The two will become one flesh.” But he who unites himself with the Lord is one with Him in spirit. Flee from sexual immorality. Every other sin a man can commit is outside his body, but he who sins sexually sins against his own body. Do you not know that your body is a temple of the Holy Spirit who is in you, whom you have received from God? You are not your own; you were bought at a price. Therefore glorify God with your body.

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.

My son, pay attention to my wisdom; incline your ear to my insight, that you may maintain discretion and your lips may preserve knowledge. Though the lips of the forbidden woman drip honey and her speech is smoother than oil, in the end she is bitter as wormwood, sharp as a double-edged sword. Her feet go down to death; her steps lead straight to Sheol. She does not consider the path of life; she does not know that her ways are unstable. So now, my sons, listen to me, and do not turn aside from the words of my mouth. Keep your path far from her; do not go near the door of her house, lest you concede your vigor to others, and your years to one who is cruel; lest strangers feast on your wealth, and your labors enrich the house of a foreigner. At the end of your life you will groan when your flesh and your body are spent, and you will say, “How I hated discipline, and my heart despised reproof! I did not listen to the voice of my teachers or incline my ear to my mentors. I am on the brink of utter ruin in the midst of the whole assembly.” Drink water from your own cistern, and running water from your own well. Why should your springs flow in the streets, your streams of water in the public squares? Let them be yours alone, never to be shared with strangers. May your fountain be blessed, and may you rejoice in the wife of your youth: A loving doe, a graceful fawn— may her breasts satisfy you always; may you be captivated by her love forever. Why be captivated, my son, by an adulteress, or embrace the bosom of a stranger? For a man’s ways are before the eyes of the LORD, and the LORD examines all his paths. The iniquities of a wicked man entrap him; the cords of his sin entangle him. He dies for lack of discipline, led astray by his own great folly.
