Just because two people are Christians, doesn't mean they have to be best friends. Or hang out. They just have to be friendly. A lot of times we have this thought that we have to be friends with somebody just because they are a Christian too. But that doesn't make a whole lot of sense. I wouldn't want to hang out all the time with a home-schooling, cross-stitching, TBN-watching Christian. But I would be nice to them.
It's okay to disagree with other Christians, so long as the relationship is maintained. JM
