3 The husband should give to his wife her conjugal rights, and likewise the wife to her husband. 4 For the wife does not rule over her own body, but the husband does; likewise the husband does not rule over his own body, but the wife does. 5 Do not refuse one another except perhaps by agreement for a season, that you may devote yourselves to prayer; but then come together again, lest Satan tempt you through 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.
