Don't team up with those who are unbelievers. How can righteousness be a partner with wickedness? How can light live with darkness?
See 2 Corinthians 6:14
Partnership, whether in business or marriage, is the teaming up of one with another to act as one. God warns us against a partnership that is unequally yoked - one who loves God and one who doesn't. For how can these two different belief systems act as one? BE BLESSED!!!!!!!!!
Can two walk together, except they be agreed?
