Second Corinthians (KJV) tells us not to be “unequally yoked” with an unbeliever.The imagery is of two incompatible oxen sharing the same yoke.
The passage goes on to say that there is no harmony between Christ and Belial (Satan).
There can be no spiritual harmony in a marriage between a Christian and a non-Christian.
Instead of working together to pull the load, they would be working against each other.
While this passage does not specifically mention marriage, it definitely has implications for marriage.
The Bible also says, “Do not be misled: ‘Bad company corrupts good character’ (1 Corinthians ).
Having any kind of intimate relationship with an unbeliever can quickly turn into something that is a hindrance to your walk with Christ.If you were dating an unbeliever, what would honestly be your priority, romance or winning a soul for Christ? Is it wrong for a couple to live together before marriage?We are called to evangelize the lost, not be intimate with them.There is nothing wrong with building quality friendships with unbelievers, but that is as far as it should go.Paul goes on to remind believers that they are the dwelling place of the Holy Spirit, who inhabits their hearts at salvation (2 Corinthians -17).Because of that, they are to be separate from the world—in the world, but not of the world—and nowhere is that more important than in life’s most intimate relationship—marriage.
