This sermon introduces the book of Jude as a critical 'battlefield letter' for the last days, urging believers to earnestly contend for the faith against rising apostasy. The speaker traces the historical and theological context of Jude, highlighting his identity as a humble servant of Christ and his connection to the early church leadership, including his brother James. Key themes include the danger of false teachers who pervert grace into licentiousness, illustrated by biblical examples such as Israel, Sodom, and Korah. The message emphasizes a dual mandate: to defend the truth with conviction while simultaneously exercising compassion to rescue those caught in deception. The sermon concludes with the assurance that God preserves believers from falling, enabling them to stand faultless before His glory with exceeding joy.
