Marriage is an arrangement, an institution of God. Just as must all submit to governments and to institutions such as employment, so wives must submit to husbands and husbands must submit to God’s rules for marriage, so there are four submissions that Peter deals with in the course of these verses.
The very easiest teacher for a proud person to learn from is one that presents no threat to his pride and therefore the submissive wife who evidently shows that she desires only the good of her husband is most suitable under the hand of God to open his heart to gospel truth. She becomes a living example of the graciousness of God. This humble conduct of the wife will have a melting effect upon the unbelieving husband as she also prays constantly for the change she longs for in him. This will be a difficult calling for her, and she will perhaps experience much pain and need to exercise much patience before she sees God answer her prayers, but Peter says that her conduct may be the instrument that God uses in such cases to win the one who is far away from him.
Can someone be won without the word? Well, of course not! The apostle Peter doesn’t mean that. These are husbands who know the word and have repudiated it, so they are not being won without any knowledge of the gospel. But something else beside the word has come in to influence them greatly. They behold or fix their gaze upon and watch carefully the behaviour of the wife. Her chaste behaviour, her character, her devotion and reverence to God has made a deep impression on them. It may be that this leads to the salvation of the unconverted husband. Further attempts to speak directly to him may antagonise him more, and even though that response would be sinful, the believing wife is to employ wisdom. She must wait for God to act. Her gracious responses and evident intention to submit to her husband will soften his heart under the hand of God. What she must not do is reason that her own conversion has set her free from an obligation to live within the bounds of marriage. Marriage is for this world not the next, but while we are here we cannot overturn this institution of God.
Why, coupled with fear? Fear of your husband who is an unbeliever? Fear of your wife who is an unbeliever? No, the fear word means fear of discrediting God or the gospel, fear of falling into self-pity and misery, and perhaps even bitterness. ‘Coupled with fear’, reverence and respect for God, and fear of not being a witness.
What is the Christian’s attitude to divorce? Divorce should only follow adultery or desertion (and desertion may well include violence), when somebody repudiates their marriage and refuses to live peaceably and properly with the other party. Divorce is for these extreme situations. There is no such thing in the New Testament as light divorce for Christians. ‘Oh, we don’t get on’, or, ‘I don’t love him anymore’, or, ‘I don’t love her anymore.’ Love is a choice. Don’t ever let our thinking be influenced by the world around us, which has rejected the word of God and created its own rules and standards. ‘Should we be separated, should we be divorced?’ Well, is there serious adultery? Is there violence? Is there desertion? ‘Oh, no.’ Well, then, there is no question of divorce, not in the Scripture. That is not unsympathetic. We are as sympathetic as we can possibly be to anybody who for the Lord stands for him in a marriage, where their spouse does not trust in God or love him. But it is not a case for divorce.
