The book of Jude is a General Epistle (Apostolic Letter). The author is Jude the brother of James, both of who are half-brothers of Jesus Christ. Jude wrote it circa 75 A.D.
The purpose of this book is to address false teachings and to illustrate a contrast between the error of heresy and the truth of Jesus Christ. Jude consists of only one chapter.
Verses 1- 16 – Jude identifies himself and quickly delves into the dilemma of false teachings.
“For there are certain men crept in unawares, who were before of old ordained to this condemnation, ungodly men, turning the grace of our God into lasciviousness, and denying the only Lord God, and our Lord Jesus Christ” (vs. 4)
Heresy was obviously seeping into the region, disturbing the churches, and deceiving believers. He begins by illustrating similarities between false teachers and condemned individuals from the Old Testament citing Cain, Balaam, and Korah.
Verses 17-25 – Jude urges Christians to…
“But, beloved, remember ye the words which were spoken before of the apostles of our Lord Jesus Christ“(vs. 17).
He was referring to all of the apostles and disciples in the past, which had warned about false teachers and prophets that were coming to deceive.
His advice is to focus on Jesus Christ and to watch out for each other so that no one is misled into error.
Those who place their faith and trust in Jesus Christ are secure in salvation, not by their own good deeds, because no one is good enough to do that, but believers are secure by the vicarious work of Jesus Christ on the Cross.
Now unto him that is able to keep you from falling, and to present you faultless before the presence of his glory with exceeding joy,
To the only wise God our Savior, be glory and majesty, dominion and power, both now and ever. Amen (vs. 24-25).
