1 Corinthians 7:13

13 And if a believing woman has a husband who is not a believer and he is willing to continue living with her, she must not leave him.

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 if she does leave him, let her remain single or else be reconciled to him. And the husband must not leave his wife.
12 Now, I will speak to the rest of you, though I do not have a direct command from the Lord. If a fellow believer has a wife who is not a believer and she is willing to continue living with him, he must not leave her.
13 And if a believing woman has a husband who is not a believer and he is willing to continue living with her, she must not leave him.
14 For the believing wife brings holiness to her marriage, and the believing husband brings holiness to his marriage. Otherwise, your children would not be holy, but now they are holy.
15 (But if the husband or wife who isn’t a believer insists on leaving, let them go. In such cases the believing husband or wife is no longer bound to the other, for God has called you to live in peace.)
