36 If anyone is worried that he might not be acting honorably toward the virgin he is engaged to, and if his passions are too strong and he feels he ought to marry, he should do as he wants. He is not sinning. They should get married.37 But the man who has settled the matter in his own mind, who is under no compulsion but has control over his own will, and who has made up his mind not to marry the virgin—this man also does the right thing. 38 So then, he who marries the virgin does right, but he who does not marry her does better. 39 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.40 In my judgment, she is happier if she stays as she is—and I think that I too have the Spirit of God.—1 Cor. 7:36-40 NIV
This is Paul’s warning against sex outside of marriage. In those times, most marriages were pre-arranged, so the person knew who they would be marrying. Therefore, Paul could make this warning specific to a particular person. In today’s world of dating, the warning would have to be generalized to mean any person with whom you are in any sort of social relationship. The couple, if they are unable to control themselves physically, should either stop the relationship or agree to get married and do so before the physical relationship leads both of them to sin. Either decision will keep us from doing the wrong thing. That does not mean that we rush into marriage just so we can have sex. There are “good” things and then there are “God” things. Search for and do the “God” thing, not the thing that feels good. Experience teaches us that if our marriage choices are not soaked in prayer, the end result can be disastrous. Once the marriage is consummated, praying together will keep the marriage together. Less than 1% of marriages where the couple pray together daily end in divorce.
If you make the decision to marry, then you are bound to each other “until death do us part”. Jesus set the example for us since He will never forsake the church
31 “For this reason a man will leave his father and mother and be united to his wife, and the two will become one flesh.” 32 This is a profound mystery—but I am talking about Christ and the church. 33 However, each one of you also must love his wife as he loves himself, and the wife must respect her husband.—Eph. 5:31-33 NIV
