The Book of Jude is a short but powerful letter warning Christians about false teachers who have crept into the church, distorting the gospel and leading others into immorality. Jude urges believers to defend the faith, remain steadfast, and remember God’s past judgments on the wicked. He uses examples from history, including fallen angels and Sodom and Gomorrah, to emphasize the consequences of rebellion. The letter ends with an encouragement to persevere in faith and a beautiful doxology praising God’s power to keep His people from falling.
