Don't team up with those who are unbelievers. How can righteousness be a partner with wickedness? How can light live with darkness? What harmony can there be between Christ and the devil? How can a believer be a partner with an unbeliever?
See 2 Corinthians 6:14-15
God warns against relationships in which one loves God and the other doesn't because these will naturally lead to conflict or to spiritual compromise. BE BLESSED!
