1 Corinthians 7 :: New International Version (NIV)
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.
