It’s instructive that the Bible not only alerts us to watch out for doctrinal heresy, but also for relational heresy. The Bible commands us not only to be careful out there about people who are false teachers; we also must be careful out there about people who are false lovers—divisive, biting, devouring, overbearing, quarrelsome, and contentious people. Consider just a few of the times that the Bible warns us to be careful, to be on guard against, and to watch out for divisive people.
