1 Corinthians 7:13 Meaning and Commentary

1 Corinthians 7:13

And the woman which hath an husband that believeth
The apostle puts the case both ways, there being the same reason for one as for another; that if she that was a sister, who was partaker of the grace of God, and a member of the church, had a husband to whom she was married before her conversion; who was an unbeliever, had no faith in Christ, nor any notion of the Gospel, but an infidel to both:

and if he be pleased to dwell with her;
loves her, and is willing to continue with her; neither puts her away from him, nor departs from her on account of her Christianity:

let her not leave him;
but continue, and cohabit with him as man and wife; this is the advice the apostle gives, as agreeably to the light of nature and reason; as becoming the Gospel of Christ, and as what might serve to recommend it, and spread the knowledge of it.

1 Corinthians 7:13 In-Context

11 but and if she may separate, let her remain unmarried, or to the husband let her be reconciled, and let not a husband send away a wife.
12 And to the rest I speak -- not the Lord -- if any brother hath a wife unbelieving, and she is pleased to dwell with him, let him not send her away;
13 and a woman who hath a husband unbelieving, and he is pleased to dwell with her, let her not send him away;
14 for the unbelieving husband hath been sanctified in the wife, and the unbelieving wife hath been sanctified in the husband; otherwise your children are unclean, but now they are holy.
15 And, if the unbelieving doth separate himself -- let him separate himself: the brother or the sister is not under servitude in such [cases], and in peace hath God called us;
