From the beginning of time, God’s design for marriage was for a male and a female to become united as one ... united physically, mentally, emotionally and spiritually. If spiritual oneness has eluded you, that is all the more reason to be the Lord’s silent witness before your unbelieving mate. Never lose hope...
“We have been unfaithful to our God by marrying foreign women from the peoples around us. But in spite of this, there is still hope for Israel.”
An unequally yoked marriage is the union of a husband and wife in which one is a believer and the other is an unbeliever.
The Bible tells believers to avoid becoming yoked with unbelievers.
“Do not be yoked together with unbelievers. For what do righteousness and wickedness have in common? Or what fellowship can light have with darkness?”
2 Corinthians 6:14
A believer is a person who has a personal relationship with Jesus Christ and who seeks to live a life relying on the Lord for everything.
Mere intellectual assent that Jesus is Lord is not evidence that one is a believer. A changed life is the evidence of authentic salvation.
“Not everyone who says to me, ‘Lord, Lord,’ will enter the kingdom of heaven, but only the one who does the will of my Father who is in heaven” Matthew 7:21
An unbeliever is a person who does not have a personal relationship with Jesus Christ and who lives life trusting and relying on human effort instead of relying on the Lord for everything.
“What does a believer have in common with an unbeliever?”
2 Corinthians 6:15
“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. For 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. But if the unbeliever leaves, let it be so. The brother or sister is not bound in such circumstances; God has called us to live in peace. How do you know, wife, whether you will save your husband? Or, how do you know, husband, whether you will save your wife?”
1 Corinthians 7:12–16
“Be wise in the way you act toward outsiders; make the most of every opportunity. Let your conversation be always full of grace, seasoned with salt, so that you may know how to answer everyone.”
1 Corinthians 13:1–8, 13
2 Corinthians 3:18
