Jude: A Study from the Brother of Jesus by Ed Rangel

Twenty-five verses. One urgent command: contend earnestly for the faith. This 14-lesson workbook walks through the New Testament's last line of defense against corruption inside the church.

Jude: A Study from the Brother of Jesus is a 14-lesson workbook by Ed Rangel covering the entire epistle verse by verse. Jude sat down to write about the salvation all Christians share, but the crisis in front of him demanded something more urgent — false teachers had crept into the fellowship, twisting the grace of God into a license for immorality and denying the authority of Christ. His short letter stands in the long biblical tradition of the watchman on the wall: the one who sees danger coming and must sound the alarm.

Rangel treats that warning as a living word for the church today. The lessons follow Jude's own movement — from believers who are called, loved, and kept, through the exposure of the intruders and the certainty of judgment, to the commands to build, keep, watch, and show mercy with discernment — ending where Jude ends, with the doxology to the God who is able to keep His people from stumbling.

What's Inside

Fourteen lessons tracing the epistle from greeting to doxology:

• Lesson 1 — Called, Loved, Kept (Jude 1–2)
• Lesson 2 — The Faith Once for All Delivered (Jude 3)
• Lesson 3 — The Invasion: Grace Turned into License (Jude 4)
• Lesson 4 — Privilege Is No Guarantee Against Judgment (Jude 5–7)
• Lesson 5 — The Diagnosis of Rebellion (Jude 8–10)
• Lesson 6 — Three Roads to Ruin: Cain, Balaam, Korah (Jude 11)
• Lesson 7 — Rotten at the Core: Portrait of Apostates (Jude 12–13)
• Lesson 8 — Enoch and the Certainty of Judgment (Jude 14–15)
• Lesson 9 — The Anatomy of False Teachers (Jude 16)
• Lesson 10 — Remember the Apostles, Prepare for the Times (Jude 17–19)
• Lesson 11 — Building, Keeping, Waiting (Jude 20–21)
• Lesson 12 — Mercy with Discernment (Jude 22–23)
• Lesson 13 — Kept from Stumbling: The Final Doxology (Jude 24–25)
• Lesson 14 — Why Jude Comes Before Revelation

Format & Features

Each lesson pairs careful exposition with Greek word studies, discussion questions, and written reflection prompts that press the text into practice. Beyond the lessons, the book includes an introduction to the epistle's background and setting, five appendices (key terms, cross-references, Jude's threefold witness patterns, and more), a selected bibliography, and a full "Preaching Jude" section with expository and topical sermon outlines — making it as useful in the pulpit as in the classroom. Scripture quotations are from the NASB 1995. Designed for a lesson-per-week rhythm in Bible classes, small groups, or personal study.

Who It's For

Bible class teachers, preachers, elders, small-group leaders, and any Christian who takes seriously the call to guard the faith once for all delivered to the saints — especially congregations navigating an age of competing religious voices.
