The little book of Jude kind of comes out of nowhere. Landing right before Revelation, it is thought to have been written by one of the biological brothers of Jesus, and he seems pretty concerned about false teachers who had found their way into groups of believers. They sow seeds of discord instead of harmony. They are arrogant instead of humble. They ridicule instead of trying to understand. These are pretty good standards for us today. If we look like any of those false teachers, we may be one ourselves.
