1 Corinthians 7:4
The wife hath not power of her own body, but the husband: and likewise also the husband hath not power of his own body, but the wife.
Note 6 at 1Co 7:4: These are some amazing statements that do not sit well with the thinking of most people today. It would be unthinkable to many people that their mates could have access to them sexually at any time. They would say, "What about my rights?" Paul was saying that when people marry, they yield their rights to their mates, even down to the most intimate details.
If people today would realize that this is the way it is in a godly marriage, they would take the selection of a mate much more seriously, and they would have fewer problems in their marriages.
Of course, it needs to be qualified that the Lord is speaking about normal sexual relationships. This is not saying that either partner has to yield to any type of perverted sexual acts.
