This isn’t to say that unbelievers can’t be good people, but I am saying I’d discourage you from dating someone who isn’t on the same spiritual foundation as you.
In 2 Corinthians , the Apostle Paul says that believers should not "be unequally yoked with non-believers." While it's true that this passage does not specifically mention marriage, it does refer to being bound in a relationship with another person—no relationship is more binding than marriage.
Anyone who doesn’t encourage you to seek a deeper relationship with God, isn’t someone worth giving your time to.
This might sound harsh, but I promise you it’s a standard worth implementing.
I understand that God can use all things to work together for the good of those who are in Christ, but I cannot help but wonder if God would encourage a relationship that is unequally yoked. I’m not ignorant enough to think that God hasn’t used an unequally yoked couple for His good, but I will still fall on the side of discouraging relationships where both parties aren’t on the same spiritual page. (Proverbs 16)Your relationship with God should always be put above your relationship with anyone else, and that includes your future spouse.
My wife and I both encourage one another to make God our first priority, and in doing so, our relationship with each other will flourish.
