Paul’s Warning Against Tolerated Sin and the Shepherd’s Burden in a Confused Age
2 Corinthians 12:19-21
"Have you been thinking all along that we have been defending ourselves to you? It is in the sight of God that we have been speaking in Christ, and all for your upbuilding, beloved. For I fear that perhaps when I come I may find you not as I wish, and that you may find me not as you wish; that perhaps there may be quarreling, jealousy, anger, hostility, slander, gossip, conceit, and disorder. I fear that when I come again my God may humble me before you, and I may have to mourn over many of those who sinned earlier and have not repented of the impurity, sexual immorality, and sensuality that they have practiced."
In verse 19, Paul clarifies his entire letter’s tone:
His words haven't been a self-defense before the Corinthians but spoken "in the sight of God" and "in Christ," aimed entirely at their upbuilding (the edification, and strengthening of otherwise weak faith). He’s not posturing for approval; he’s laboring as a spiritual father for their growth. He dreads finding the church marked by relational sins, "deeds of the flesh" that destroy community. Paul is worried that the church will remain immature, prone to infighting, (quarreling, jealousy, anger, hostility, slander, gossip, conceit, and disorder) rather than a humble, gospel-centered love.
A father’s sorrow is profound when his children persist in sin rather than maturing. Paul, their spiritual father, doesn’t fear the nonsense of relativistic arguments per se, but moreso the underlying spiritual condition that produces them; pride, worldliness, and refusal to submit to gospel truth. He fears arriving to a church still dominated by the flesh, requiring painful discipline rather than joyful fellowship.
It's a lot like family reunions. Whether literal holiday gatherings or the kind of long-awaited returns Paul anticipates in 2 Corinthians 12; often these reunions expose how little the mere passage of time does to mend deep relational fractures. We hope absence will soften edges, dull memories, or let offenses fade into the background, but instead, the old wounds can resurface sharper than before, triggered by proximity, unresolved words, or unchanged patterns of behavior.
Paul's not just worried about surface-level awkwardness or debates; he’s dreading the discovery that the Corinthian "family" hasn’t truly healed in his absence. And that he's going to be forced into taking a hardline. He’s not eager for confrontation; quite the opposite. As a spiritual father, he dreads having to step into the role of a disciplinarian. He’d far prefer a joyful reunion, mutual encouragement, and seeing the fruit of his labors in their maturity and holiness. But their persistent lack of self-control; the unrepented impurity, sexual immorality, and sensuality, alongside the relational toxins like quarreling, jealousy, anger, slander, conceit, and disorder, has forced his hand and the situation to this point.
He’s clear that this isn’t his preference. Paul sees this situation as a humbling task he must take on, a painful necessity of confronting their sin head-on. He anticipates mourning over many who sinned earlier and haven’t repented. Not an "I told you so". It’s the grief of a pastor who loves them deeply and hates what sin does to them.
Why worry, why not just let the people continue in their sin, let the Lord sort them all out?
Paul knows what sin does to them and to the body of Christ. He knows that ignoring it would be unloving, allowing the leaven to spread throughout the whole lump. And it also had the side effect of encouraging these "superapostles" (false gospel teachers) who were coming into the church and ripping the people off.
Sin is contagious and corrupting within the body of Christ. A single unaddressed, unrepented sin, especially sexual immorality, doesn’t stay isolated. It spreads influence, normalizes compromise, dulls consciences, and erodes the church’s collective holiness. We see this happening everywhere today within all the denominations of Christianity throughout the West.
In mainline Protestant bodies (United Methodist Church, Presbyterian Church USA, Episcopal Church, Evangelical Lutheran Church in America), shifts toward affirming same-sex marriage, ordination of LGBTQ+ clergy, and blessing same-sex unions have accelerated. But these are the result of many decades of immoral behaviors even among the heterosexual community. These behaviors didn’t emerge in a vacuum; they’re frequently the downstream fruit of decades-long tolerance. Tolerance that began with Fornication (premarital sex) which is profoundly problematic in every Christian community. Not to mention related heterosexual sins like cohabitation, adultery, pornography use, and casual sexual encounters. When a community quietly accommodates or excuses "lesser" sexual sins within its own ranks, it erodes the moral framework needed to uphold biblical sexual ethics consistently. Over time, this creates a slippery slope. If heterosexual fornication is winked at or reframed as "committed love" outside marriage, it’s harder to draw firm lines on other forms of sexual expression without appearing hypocritical.
Heterosexual sins often precede or parallel broader shifts in the culture. Many denominations that later affirmed same-sex unions had already moved toward accepting divorce/remarriage more leniently, cohabitation as a "trial marriage," or casual sex as a private matter. The church’s failure to address the full spectrum of "porneia" (sexual immorality) allowed the leaven to spread, leading to these divisions, immaturity, and unrepentant behaviors that Paul is mourning here. This is a timely reminder for the Christian faith community today. Around 57% of all Christians in several polls have said sex between unmarried adults in a committed relationship is acceptable, with even higher rates among mainline Protestants (around 67%). Among younger folk it hovers around 70-80%.
This gradual compromise dulls the conscience on holiness, and Paul knows it, as should we.
Unaddressed fornication normalizes compromise, weakens teaching on self-control and purity, and fosters a culture where personal desires trump biblical commands. And time only erodes the teaching even more. When heterosexual immorality goes unchallenged for generations, the church loses all credibility to call any sexual sin to repentance, leading to either silence or full accommodation to avoid accusations of selective judgment. Fornication isn’t a "minor" issue, it’s profoundly problematic. It's an open festering wound.
If sinners are left to their own to believe what they will, by what power do they do it?
The answer Scripture gives is unflinching; none at all in themselves. The Scriptures don’t flatter us with ideas of innate goodness or neutral potential; they declare us dead from the start. Every person, every soul that comes into this world is a lifeless corpse. Every person enters this world spiritually dead in trespasses and sins. So immediately we can shrug off these emotions that suggest that people are essentially good. Paul states it plainly in Ephesians 2:1–5. This "deadness" isn’t a mere sickness or impairment that a person can overcome with enough willpower, education, or moral effort. A corpse doesn’t decide to get up, breathe, or respond to a call; it’s utterly powerless, incapable of life or movement apart from external intervention.
So it is with the unregenerate heart; enslaved to sin, hostile to God. Left to themselves, sinners suppress truth in unrighteousness; chase desires of the flesh and mind, and remain children of wrath. There is no innate power to turn, repent, or believe the gospel. God alone can create that restoration. God makes the dead alive (Ephesians 2:5). By grace through faith; and even that faith is not of ourselves; it is the gift of God.
Left to our own we chase fleshly desires, remain under wrath, and have no innate power to turn, repent, or believe. Oh we may make bargains in the end, play at acknowledging God's mercy and grace due to the inconvenient truth that our bodies are actually about to die. But what we missed all along was we were already dead to our sins if we hadn't already repented and received God's gift of faith in Christ.
No one merely stumbles into sin; we all pursue fleshly desires with an enslaved zeal. Scripture exposes the fatal flaw in the deathbed strategy; we were already dead long before the body fails. A corpse doesn’t bargain its way back to life; it lies lifeless until sovereign power intervenes. Until Christ calls that body and soul back to life, that dead sinner is just plain dead. If repentance and faith haven’t been granted by God earlier; through the regenerating work of the Spirit quickening the heart to see Christ’s worth and hate sin for what it is, then the final moments offer no automatic escape hatch. The "gift of faith" (Ephesians 2:8) isn’t conjured by desperation; it’s bestowed by grace, often in ways that bear fruit over time, not just in a panicked whisper.
There's an old Puritan saying:
"true repentance is never too late, but late repentance is seldom true."
Why?
Because genuine repentance involves:
1. A deep recognition of sin as offense against God. That's key!
2. Genuine sorrow that grieves the heart of God. That reveals our heart, and motives.
3. A turning, a resolve to forsake sin and pursue righteousness. Rare without a prior softening of the heart.
This doctrine crushes any illusion of self-salvation or the delayed surrender to grace. And establishes the principle that the power to resurrect the dead is GOD'S power ONLY! The scriptures never offer any justification for thinking it is left up to the individual to choose God.
God chooses us!
Paul’s deep concerns for the Corinthian church in revolve around persistent, tolerated sin that refuses to yield to repentance. This isn’t isolated incidents of stumbling but ongoing patterns of impurity, sexual immorality, and sensuality that have gone unaddressed, alongside relational poisons. These aren’t new problems, and they have yet to be resolved in church history. Today we see the downstream effects in modern mainline denominations persisting. At root, these problems stem from the same misplaced ideas Paul battled; thinking sin can be managed, excused, or reframed without full repentance.
The call remains urgent; repent now, pursue holiness together, depend on Christ’s resurrecting power. May the Lord awaken His church to purge the leaven, restore purity, and shine as a faithful witness in a compromised age. It's going to mean that there must be faithful Shepherds teaching truth, and accountability. And their task is going to be extremely complicated in our culture in this age of confusion that is currently arguing foundational truths about human identity, biology, and God’s design for sexuality.
Today Shepherds must navigate these legal minefields while prioritizing soul care over institutional preservation. The church cannot retreat into silence on these matters. Like Paul, though they may want a different focus, they must face these leavening challenges head-on. Faithful Shepherds must proclaim holiness boldly, extend mercy freely, and trust Christ’s resurrecting power to awaken hearts in this confused age.
May the Lord raise up such shepherds in abundance; men and women who fear God more than courts or culture, who shepherd with integrity, and who lead flocks to shine as lights in darkness.
In Jesus Christ's Holy name, amen.
