Jude and the Subverters

Today's Scripture

The whole letter of Jude is twenty-five verses. Read it twice today. Here is its heart.

Jude 3-4 — "I found it necessary to write appealing to you to contend for the faith that was once for all delivered to the saints. For certain people have crept in unnoticed... ungodly people, who pervert the grace of our God into sensuality and deny our only Master and Lord, Jesus Christ."

Jude 22-23 — "And have mercy on those who doubt; save others by snatching them out of the fire; to others show mercy with fear, hating even the garment stained by the flesh."

Jude 24 — "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."

The Big Idea

Jude wanted to write a happy letter about salvation. Instead he had to write an urgent one, because smooth-talking teachers had slipped into the church and turned grace into a permission slip for sin. His little letter shows us how to fight for the truth without turning bitter — and it ends not with our grip on God, but with God's grip on us.

Reflection

Grace twisted into a permission slip

Jude tells us his plans changed. He sat down to write about "our common salvation," and the news forced his pen another direction (v. 3). Certain people had "crept in unnoticed" — the Greek word pictures spies slipping into a city — and were teaching something that sounded wonderfully gracious: God forgives everything, so live however you like.

Jude 4 — they "pervert the grace of our God into sensuality." Sensuality is an old word for letting your appetites drive the car. Notice the method. These teachers did not attack grace. They weaponized it. They took the most beautiful word in the Christian faith and bent it into a license.

Paul had already met this move and given it the sharpest answer in his vocabulary. Romans 6:1-2 — "Are we to continue in sin that grace may abound? By no means!" And nineteen centuries later, Dietrich Bonhoeffer gave the counterfeit its lasting name — cheap grace:

"Cheap grace is the preaching of forgiveness without requiring repentance, baptism without church discipline, Communion without confession, absolution without personal confession. Cheap grace is grace without discipleship, grace without the cross, grace without Jesus Christ, living and incarnate." — Dietrich Bonhoeffer, The Cost of Discipleship

Grace without the cross. That is what had crept into Jude's churches, and it still creeps. So Jude says: contend — fight, strain, defend — "for the faith that was once for all delivered to the saints" (v. 3). The faith is not ours to update; it was delivered, entrusted, like a family inheritance. John Calvin felt the obligation in his bones:

"A dog barks when his master is attacked. I would be a coward if I saw that God's truth is attacked and yet would remain silent." — John Calvin, Letters

Some silence is not humility. It is cowardice with good manners. Jude will not allow it.

Three old roads to ruin

To explain the intruders, Jude reaches back into Genesis and Numbers and pulls out three names. Jude 11 — "Woe to them! For they walked in the way of Cain and abandoned themselves for the sake of gain to Balaam's error and perished in Korah's rebellion."

Cain is the road of envy. His offering was rejected and his brother's accepted, and instead of repenting he turned on his brother. God's warning to him names the danger for all of us. Genesis 4:7 — "sin is crouching at the door. Its desire is contrary to you, but you must rule over it." In the church, the way of Cain is the leader who cannot celebrate another's blessing — who builds his platform out of attacks on other ministries. It gets called boldness. It is envy.

Balaam is the road of greed. His strange story fills Numbers 22-24: a real prophet, with a real gift, offered real money to curse Israel. God would not let him curse, so he found a workaround — he taught Israel's enemies how to corrupt Israel from within (Numbers 31:16). The way of Balaam is the gifted teacher whose gift slowly bends toward whatever pays. The wages are not always cash. Sometimes they are applause, access, a bigger room.

Korah is the road of proud rebellion. He was already a Levite, already in ministry, and he wanted Moses' place. His slogan even sounded humble and democratic. Numbers 16:3 — "all in the congregation are holy, every one of them... Why then do you exalt yourselves?" It was a power grab dressed as a principle. The way of Korah is the insider who decides he deserves the authority God gave to others.

Envy, greed, pride. Nothing exotic. These are the recurring sins of every human heart — which is exactly Jude's unsettling point. The intruders did not come from another species. They came from the same fallen stock we did. Notice, too, that two of the three were already in ministry: Balaam was a genuine prophet, Korah a genuine Levite. False teachers are not usually outsiders who hate the church. They are insiders whose ordinary sins were never put to death, and who grew a platform faster than they grew a soul. Discernment that forgets this — that treats false teachers as monsters instead of mirrors — stops being discernment and becomes Cain's road by another route.

Contending without contempt

So how do we fight without becoming the thing we are fighting? Watch where Jude turns next, because it is not where the internet would turn.

He does not organize a purge. He tells the church to tend its own soul. Jude 20-21 — "But you, beloved, building yourselves up in your most holy faith and praying in the Holy Spirit, keep yourselves in the love of God, waiting for the mercy of our Lord Jesus Christ that leads to eternal life." Get rooted. Pray. Stay warm. Keep the end of the story in view. A guard who never sleeps becomes useless; a watchdog that bites everyone protects no one.

Then come the most surgical instructions in the letter. Jude 22-23 — "have mercy on those who doubt; save others by snatching them out of the fire; to others show mercy with fear." Three kinds of people, three responses. The doubter needs gentleness, not a lecture. The one at the cliff's edge needs an urgent hand, now. The deeply entangled still gets mercy — but careful mercy, the kind that knows how flammable the rescuer's own heart is. Paul gives the same safety briefing in Galatians 6:1 — restore the fallen "in a spirit of gentleness. Keep watch on yourself, lest you too be tempted."

We all know what ignoring this looks like, because we have watched it in a group chat: someone says something off, and the pile-on starts, and within an hour the correctors have committed more sins than the corrected. John Newton — the former slave trader who wrote "Amazing Grace" — diagnosed the disguise our pride wears in a fight:

"There is a principle of self, which disposes us to despise those who differ from us; and we are often under its influence, when we think we are only showing a becoming zeal in the cause of God." — John Newton, Letter 'On Controversy'

We can feel righteous while merely feeling superior. John Wesley warned a young friend that knowledge alone would not protect him from this:

"Beware you be not swallowed up in books! An ounce of love is worth a pound of knowledge." — John Wesley, Letter to Joseph Benson

And Francis Schaeffer raised the stakes: the watching world is allowed to judge our message by our love.

"Yet, without true Christians loving one another, Christ says the world cannot be expected to listen, even when we give proper answers." — Francis Schaeffer, The Mark of the Christian

Truth without love does not merely fail to persuade. It teaches people that the truth is unlovely. Jude refuses the trade in both directions: no surrendering the faith to be nice, and no surrendering kindness to be right.

Kept by the One who never stumbled

Why can Jude be both ferocious and tender on the same page? Because of where his letter lands. He does not end with "so stay vigilant." He ends with a song.

Jude 24-25 — "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."

He is able to keep you. After twenty-three verses about creeps, wolves, and the roads of Cain, Balaam, and Korah, the final word is not our alertness but God's grip. This is the gospel underneath all discernment: Jesus walked every road we fail on. Offered every shortcut Balaam took, he stayed poor. Holding all authority Korah grasped at, he knelt with a towel. Envied and hated as Abel was, he let the violence fall on himself — and his blood, Hebrews says, speaks a better word. He never stumbled, and then he died for stumblers, and rose to present them "blameless... with great joy."

Tim Keller compresses that into the sentence every contender needs taped to the mirror:

"The gospel is this: We are more sinful and flawed in ourselves than we ever dared believe, yet at the very same time we are more loved and accepted in Jesus Christ than we ever dared hope." — Tim Keller, The Meaning of Marriage

A person who knows the first half cannot sneer at the deceived — there but for grace go I. A person who knows the second half cannot go soft on the truth — this grace cost the cross, and it is not for sale cheap. Hold both, and you can contend all your life without becoming the bitter version of yourself.

Going Deeper

Think of one real person in your life who is in the orbit of teaching that concerns you — drifting, deconstructing, or dazzled by a voice you distrust. Which of Jude's three categories fits them right now: doubting, in immediate danger, or deeply entangled? Write their name down, choose the matching response — gentle mercy, urgent honesty, or careful, prayerful distance — and take one small step toward them this week. The difference between bitter Christians and discerning ones is usually this: the discerning ones did this exercise with actual people, with actual love.
