External forces seem to be lining up against the church of Jesus Christ more and more each day. While these dangers are significant, there exists an internal threat that is just as real as external dangers facing the church. This internal threat is careless thinking and immoral living within the church. In response to this danger within the church, Dr. Brammer writes to remind and encourage the church to build a solid foundation of biblical truth so they will know when error threatens. Using the New Testament book of Jude as the guide, Dr. Brammer desires that this book will awaken believers to internal threats that will hinder them from disunity while simultaneously striving to "to contend for the faith that was once for all delivered to the saints."
