I love the short letter from Jude.
Jude sat down to write a letter of encouragement. That was the plan. He says so himself:
“Although I was very eager to write to you about our common salvation, I found it necessary to write appealing to you to contend for the faith that was once for all delivered to the saints” (v. 3).
Something had come up. Certain people had crept into the congregation unnoticed, and Jude couldn’t let it go.
So the encouraging letter never got written. Instead, we have this warning.
It’s only twenty-five verses, but don’t let that fool you. Jude isn’t pulling punches. He names what’s happening, backs it with Scripture and history, and tells his people exactly what to do about it. Let’s walk through it.
A Problem Jude Couldn’t Have Imagined
Before we get into the text, let me point out one contextual issue.
Every word Jude wrote about false teachers assumes you’re in the same room with them. He’s writing to a local congregation about people embedded in their fellowship — people they eat with, worship with, do life with. That’s the assumed setting for everything he says about discernment.
None of the New Testament authors could have dreamed about YouTube, podcasts, or a handheld device that gives you access to thousands of teachers at any moment. But that’s where we live now. And it changes things, because some of what Jude describes you can only see up close.
I listen to a handful of teachers online who I think handle the Word well. But handling the Word well isn’t a guarantee that someone isn’t a false teacher. The marks Jude is about to list aren’t all visible through a screen.
I’m not saying don’t listen to anything outside your local church. I am saying the teachers you allow to shepherd your soul should be people within a local fellowship — people who have a vested interest in you specifically. It’s no skin off a podcast host’s back if you drift. But your pastor will answer to the Lord for how he led you. That’s the kind of accountability that earns access to your soul.
What False Teachers Are Actually Doing
Jude names two things in verse 4: these teachers pervert the grace of God into sensuality, and they deny the Lordship of Jesus Christ. The two go together.
To pervert grace into sensuality means you take advantage of God’s forgiveness instead of being transformed by it. Paul asked the same question in Romans 6: “Are we to continue in sin that grace may abound?” These “teachers” answered yes. They treated Christ’s forgiveness as a license to keep following whatever the flesh wanted — food, sex, power, whatever — grace as a safety net rather than a new life. Paul’s own answer was blunt: “By no means! How can we who died to sin still live in it?”
And when grace becomes a license to sin, Jesus has quietly been moved off the throne of your life. You can’t have it both ways.
To make the stakes plain, Jude reaches for three examples. The generation God rescued from Egypt with signs and wonders — destroyed in the wilderness for following their impulses instead of trusting him. The angels of Genesis 6, who abandoned their posts to chase the lust of their eyes and ended up in eternal chains. Sodom and Gomorrah, who need no explanation. All three share one thread: they looked at what God had given them, decided their own desires were better and more satisfying, and were destroyed for it. Jude says false teachers lead people the same direction.
How to Recognize Them
Jude’s profile is detailed. These teachers rely on subjective experiences — dreams, visions, special revelation — to ground their authority (v. 8). That private knowledge becomes a leg up on everyone else, so when someone with real authority comes to correct them, they reject it: “They just don’t get it.” They speak carelessly about things in the spiritual realm they don’t actually understand (v. 10).
He also names three biblical types in verse 11: the way of Cain, the error of Balaam, the rebellion of Korah. Jealousy. Greed. Lust for power. Three men from across Israel’s story, all sharing one root — dissatisfaction with the station God had given them, and a reach for something more. False teachers are driven by the same things.
Then comes a string of meaningful visuals in verses 12 and 13.
Hidden reefs. A reef doesn’t announce itself; ships don’t run aground on what they can see. The danger is just below the surface — a teacher who looks fine, sounds reasonable, maybe draws a crowd, and quietly wrecks everyone who follows too closely.
Shepherds feeding themselves — starving the very flock they’re supposed to feed. Waterless clouds — rolling in like rain and bringing nothing, false hope to dry ground. Fruitless trees — alive in appearance only; Jesus cursed one of those. Wild waves — unpredictable, thrashing, going nowhere.
Jude closes with a behavioral list (vv. 15-16): grumblers, malcontents, led by their desires, loud boasters who show favoritism to build loyalty. They gather the discontented, stoke the discontent, and set themselves up as the voice everyone else missed. Most of us have seen this. The question is whether we named it.
So What Do You Do?
In verse 17, Jude turns to the rest of us.
Remember the Word. The apostles told you scoffers were coming. That isn’t a reason to panic; it’s preparation. You’re not caught off guard by something you were warned about.
Build yourself up in the faith. Pray in the Holy Spirit. Keep yourself in the love of God (vv. 20-21). This is interior work, and it’s where discernment actually comes from — not a critical spirit, but a relationship with the Lord deep enough that you can discern when something is off. You know the real thing, so the counterfeit stands out.
And then — don’t rush past this — have mercy on those who doubt. Snatch some out of the fire. Show mercy with fear, hating even the garment stained by the flesh (vv. 22-23). False teaching does real damage to real people, ordinary believers who got swept up in something they didn’t fully understand. The call isn’t only to expose false teaching. It’s to rescue people from it.
My Favorite New Testament Doxology
After twenty-three verses of warning, Jude lands here:
“Now to him who is able to keep you from stumbling and to present you blameless before the presence of his glory with great joy, to the only God, our Savior, through Jesus Christ our Lord, be glory, majesty, dominion, and authority, before all time and now and forever. Amen.” (vv. 24-25)
Notice where he ends. Not on the false teachers. Not on the danger. On the one who is able to keep you from stumbling.
Therefore, contend for the faith. Discern carefully. Rescue who you can. And trust the God who is able to present you blameless before his own glory.
The warning is real. But so is the one who holds you. That’s not a contradiction — that’s the Gospel.
