1 Corinthians 7:13-15

Living Bible

¹³ And if a Christian woman has a husband who isn’t a Christian, and he wants her to stay with him, she must not leave him. ¹⁴ For perhaps the husband who isn’t a Christian may become a Christian with the help of his Christian wife. And the wife who isn’t a Christian may become a Christian with the help of her Christian husband. Otherwise, if the family separates, the children might never come to know the Lord; whereas a united family may, in God’s plan, result in the children’s salvation.

¹⁵ But if the husband or wife who isn’t a Christian is eager to leave, it is permitted. In such cases the Christian husband or wife should not insist that the other stay, for God wants his children to live in peace and harmony.
