1 Cor 7:12-24
¹⁰To the married I give this command (not I, but the Lord): A wife must not separate from her husband. ¹¹But if she does, she must remain unmarried or else be reconciled to her husband. And a husband must not divorce his wife.

¹²To the rest I say this (I, not the Lord): If any brother has a wife who is not a believer and she is willing to live with him, he must not divorce her. ¹³And if a woman has a husband who is not a believer and he is willing to live with her, she must not divorce him. ¹⁴For the unbelieving husband has been sanctified through his wife, and the unbelieving wife has been sanctified through her believing husband. Otherwise your children would be unclean, but as it is, they are holy.

¹⁵But if the unbeliever leaves, let him do so. A believing man or woman is not bound in such circumstances; God has called us to live in peace. ¹⁶How do you know, wife, whether you will save your husband? Or, how do you know, husband, whether you will save your wife?

¹⁷Nevertheless, each one should retain the place in life that the Lord assigned to him and to which God has called him. This is the rule I lay down in all the churches. ¹⁸Was a man already circumcised when he was called? He should not become uncircumcised. Was a man uncircumcised when he was called? He should not be circumcised. ¹⁹Circumcision is nothing and uncircumcision is nothing. Keeping God's commands is what counts. ²⁰Each one should remain in the situation which he was in when God called him. ²¹Were you a slave when you were called? Don't let it trouble you—although if you can gain your freedom, do so. ²²For he who was a slave when he was called by the Lord is the Lord's freedman; similarly, he who was a free man when he was called is Christ's slave. ²³You were bought at a price; do not become slaves of men. ²⁴Brothers, each man, as responsible to God, should remain in the situation God called him to.
