11 (but if she departs, let her remain unmarried, or else be reconciled to her husband), and that the husband not leave his wife. 12 But to the rest I—not the Lord—say, if any brother has an unbelieving wife, and she is content to live with him, let him not leave her. 13 The woman who has an unbelieving husband, and he is content to live with her, let her not leave her husband. 14 For the unbelieving husband is sanctified in the wife, and the unbelieving wife is sanctified in the husband. Otherwise your children would be unclean, but now they are holy. 15 Yet if the unbeliever departs, let there be separation. The brother or the sister is not under bondage in such cases, but God has called us in peace. 16 For how do you know, wife, whether you will save your husband? Or how do you know, husband, whether you will save your wife?
Matthew Henry's Commentary on 1 Corinthians 7:11-16
Commentary on 1 Corinthians 7:10-16
(Read 1 Corinthians 7:10-16)
Man and wife must not separate for any other cause than what Christ allows. Divorce, at that time, was very common among both Jews and Gentiles, on very slight pretexts. Marriage is a Divine institution; and is an engagement for life, by God's appointment. We are bound, as much as in us lies, to live peaceably with all men, Romans 12:18, therefore to promote the peace and comfort of our nearest relatives, though unbelievers. It should be the labour and study of those who are married, to make each other as easy and happy as possible. Should a Christian desert a husband or wife, when there is opportunity to give the greatest proof of love? Stay, and labour heartily for the conversion of thy relative. In every state and relation the Lord has called us to peace; and every thing should be done to promote harmony, as far as truth and holiness will permit.
