Keep Your Enemies Closer

At some level, everybody has an "us" and "them" reality. There are people who are "for" me, that have my back and are in my corner, and there are people who are "against" me. Maybe it's a feuding family member. Maybe an ex who lives to see you suffer. Maybe a boss or a teacher who, for some reason, has your number. Or maybe a friend who has disowned you. So what do we do with the "them's" of our world? How does Jesus expect us to treat our enemies?
