Jude opens his epistle making it clear that his intention is to sound the alarm about “certain men” who have “crept in unnoticed.” Jude intends to expose these people and to warn the church not to let these men to seduce the church with their twisted message. These people taught that it is possible to be a believer while also engaging in sexual behavior that violates the very precepts of God’s Word, including the teaching and example of Jesus Christ. Indeed, these people even denied “the only Lord God and our Lord Jesus Christ.” So why were these people in the church, how did they get into the church, and why should these people be forced out of the church unless, of course, they repent and observe whatsoever Jesus commanded? In verses 12 and 13 Jude provides a compact but powerful answer to these questions.
