1 Corinthians 7:12-16
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. 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. 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. (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.) Don’t you wives realize that your husbands might be saved because of you? And don’t you husbands realize that your wives might be saved because of you?
God can use you to bring other people into a relationship with Jesus, including an unbelieving spouse. Don’t stop praying for people. Showcase the love of God to others, loving others as Jesus has loved you: Self sacrificially. Relationships are the lens through which people will come to know Jesus. Do everything you can to foster healthy relationships because healthy relationships within healthy boundaries are what showcases God’s love.
Today, if you’re in a relationship with someone who isn’t following Jesus—maybe a friend, a family member, a spouse or a co-worker—don’t stop praying for them. You never know how God might use you to help them see Jesus.
