1 Corinthians 7:1-19
Do not deprive each other except perhaps by mutual consent and for a time, so that you may devote yourselves to prayer. Then come together again so that Satan will not tempt you because of your lack of self-control. I say this as a concession, not as a command. I wish that all of you were as I am. But each of you has your own gift from God; one has this gift, another has that.
To 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. And if a woman has a husband who is not a believer and he is willing to live with her, she must not divorce him.
But if the unbeliever leaves, let it be so. The brother or the sister is not bound in such circumstances; God has called us to live in peace.
Why?
There are many situations among Christian family, so Paul gave us a guide to obey the word of the Lord and be a good beliver of the Lord. Don't let Satan has tempt to us.
Even between a family beliver and unbeliver need to respect each other, to be a Christian need has more witness to family. Because of the Love to attract each other.
How?
Thanks the Lord give me such wonder family and keep my marriage until now.
