In our study of 1 Corinthians chapter seven, we look at love and marriage with a non-Christian. Paul wrote this letter to the church at Corinth in response to questions that they had asked concerning a biblical marriage relationship.
"Now for the matters you wrote about: It is good for a man not to marry." NIV translation
The first six chapters of this letter dealt with some things that were going on in the local church but now the focus shifts to answering questions that they had about biblical marriage. When Paul speaks of marriage, here, he is in fact talking of a sexual relationship between a man and a woman as that was only allowed in the marriage relationship. Paul says it is good for a man to stay single but, as we shall see, there is more to it than that.
"But since there is so much 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." NIV translation
We must remember that Corinth was like the "sin city" of the day and, in fact, sex had become a religion there.
In light of this temptation that was all around them, Paul said that men and women should be joined together in a marriage relationship. The sexual relationship was appropriate in the overall marriage relationship and men as well as women should be fulfilling those needs in their marriage.
"The wife's body does not belong to her alone but also to her husband. In the same way, the husband's body does not belong to him alone but also to his wife." NIV translation
When a man and woman are joined in marriage, they give up self and the two become one (see Genesis 2). Therefore, they each belong to the other and not to themselves.
