Some Christians have come to believe that it is okay to have romantic relations with people of other religions, atheists, agnostics or unbelievers in general. But what does the Bible say? 2Cor 6:14-17 Do not be bound together with unbelievers; for what partnership have righteousness and lawlessness, or what fellowship has light with darkness? Or what harmony has Christ with Belial, or what has a believer in common with an unbeliever? Or what agreement has the temple of God with idols?
