There is no magic formula for a successful marriage and if you are married to an unbeliever, you will need to keep your focus on your Savior.
A Christian marriage should be an example of how Christ is married to the Church and so it makes no sense for a Christian to be married to an unbeliever.
1 Corinthians 7:12-14 “To the rest I say (I, not the Lord) that if any brother has a wife who is an unbeliever, and she consents to live with him, he should not divorce her. If any woman has a husband who is an unbeliever, and he consents to live with her, she should not divorce him. For the unbelieving husband is made holy because of his wife, and the unbelieving wife is made holy because of her husband. Otherwise your children would be unclean, but as it is, they are holy.”
You will be pulled in two directions— toward God and away from Him by your spouse. But you need to prioritize your relationship with God above your relationship with your spouse.
2 Corinthians 6:14 “Do not be unequally yoked with unbelievers. For what partnership has righteousness with lawlessness? Or what fellowship has light with darkness?”
The Bible tells us to not be ‘yoked’ with unbelievers. The term yoked is used when two animals are walking side by side and pulling a cart or plough. They have to be of the same size and strength or the cart would veer off to one side.
Similarly, we are told that God intends believers to marry believers of the same faith and not unbelievers or people of a different faith so that we can move in the same direction.
A mismatched marriage will bogs you down rather than make you look to the Lord of hosts, who deserves your primary allegiance, who fulfills our heart’s desires in a way our spouse never could.
1 Peter 3:1 “Likewise, wives, be subject to your own husbands, so that even if some do not obey the word, they may be won without a word by the conduct of their wives.”
It is God who helps us to love our spouse when that person doesn’t seem lovable. God loves our partner much more than we could ever do and we should rest in His presence and not in our circumstance.
Deuteronomy 7:3-4 “You shall not intermarry with them, giving your daughters to their sons or taking their daughters for your sons, for they would turn away your sons from following me, to serve other gods. Then the anger of the Lord would be kindled against you, and he would destroy you quickly.
Improve your relationship with God by spending time in prayer, studying the Bible, attending church, and getting involved in fellowship with other believers.
Your different beliefs doesn’t have to make you stop loving your spouse because you married him/her as you enjoyed each other’s company and had areas of mutual interest.
If you are married to someone of a different religion then we encourage you by saying that by your good behavior and faith in God, you are making a great impact on your spouse’s life and you should continue to be married.
But if you are not married yet and are seeing someone of another faith, then the Bible clearly warns against this.
