Jude is a short, fiery letter written with passionate urgency. The author had hoped to write about the joys of salvation but instead pivots to sound an alarm against corrupt teachers who had infiltrated the church. These individuals were twisting God's grace into a license for immorality and denying the lordship of Jesus Christ. To prove his point, Jude marshals a series of stark examples of divine judgment from the Old Testament and Jewish tradition, painting a vivid picture of the apostates' character and their inevitable doom. The letter is not merely a polemic, however; it is a powerful exhortation for believers to stand firm, build themselves up in the faith, pray in the Holy Spirit, and keep themselves in the love of God, all while trusting in the one who is able to keep them from stumbling.
