Whether people want to believe it or not, but some churches or at least some pastors/preachers do encourage their members to not be friends or not have a relationship with non Christians. Now you know, so for those of you that are Christians, I suggest you shouldn't be so eager to dismiss it so easily the next time someone mentions it again. I shouldn't have to explain why people shouldn't ignore this or any other similar issues because you ought to know it already. And if anyone who don't know why, then just asked me why and I'll tell you, it will help you and whatever group that you represent better yourselves though out life.
