3 Let the husband render to his wife the affection due her, and likewise also the wife to her husband. 4 The wife does not have authority over her own body, but the husband does. And likewise the husband does not have authority over his own body, but the wife does. 5 Do not deprive one another except with consent for a time, that you may give yourselves to fasting and prayer; and come together again so that Satan does not tempt you because of your lack of self-control.
Matthew Henry's Commentary on 1 Corinthians 7:3-5
Commentary on 1 Corinthians 7:1-9
(Read 1 Corinthians 7:1-9)
The apostle tells the Corinthians that it was good, in that juncture of time, for Christians to keep themselves single. Yet he says that marriage, and the comforts of that state, are settled by Divine wisdom. Though none may break the law of God, yet that perfect rule leaves men at liberty to serve him in the way most suited to their powers and circumstances, of which others often are very unfit judges. All must determine for themselves, seeking counsel from God how they ought to act.
