Boasting Only in the Lord: Demolishing Strongholds with the Unadorned Gospel
2 Corinthians 10:17-18
"Let the one who boasts, boast in the Lord." For it is not the one who commends himself who is approved, but the one whom the Lord commends.
Paul didn't destroy spiritual strongholds through physical force, human rhetoric, manipulation, intimidation, or worldly methods; like relying on impressive speech, personal charisma, political maneuvering, or comparisons with others (which his opponents did). Instead he took the minds of his audience captive with information, with the gospel of Jesus Christ (The Word of God). He emphasized spiritual warfare against mental and ideological fortresses.
These were not literal castles or demonic territories in a physical sense, but they referred to fortified patterns of thinking in the minds of the Corinthians. The "strongholds" were intellectual and spiritual barriers; arrogant opinions, deceptive arguments, and thoughts that opposed God’s revealed truth in Christ. Paul’s method was divine power through spiritual weapons, not human effort. He actively demolished these strongholds by proclaiming and defending the truth of the gospel. Paul’s letters themselves were part of this, weighty and powerful (v. 10), aimed at building up obedience to Christ.
His method was systematically confronting and correcting erroneous thinking. Reasoning from Scripture, correcting misunderstandings. This comports with a saying Jesus taught and gets to the heart of why sola scriptura stands as the God-given standard for the Church:
John 16:8-11
"And when he [the Holy Spirit] comes, he will convict the world concerning sin and righteousness and judgment: concerning sin, because they do not believe in me; concerning righteousness, because I go to the Father, and you will see me no longer; concerning judgment, because the ruler of this world is judged."
Convict (reprove) in this context means to expose, reprove, prove wrong, or bring to light; essentially confronting error and erroneous thinking head-on. It's about the sins of the world, but not in the sense that we might think. It's not speaking simply about murders, and thefts and such, but about the sin of unbelief.
There's only one sin that can condemn a person now, and that's the rejection of Jesus Christ. Light has come into the world, and the world has rejected it. Jesus threw his death paid the price for every sin. He didn't come to condemn the world, but to save them, because the world was already condemned. The condemnation was the rejection of the light. So the Holy Spirit came into the world concerning that sin. But not only for sin but righteousness also.
Q: Why would Jesus equate his righteousness to his ascension into heaven?
A: Jesus, ascending into heaven before the disciples, was God's statement to mankind ; "this is the righteousness that can be received into heaven". Nothing less, nothing more.
By faith in Jesus Christ's ascending to His throne, God inputs His righteousness which is in Christ through faith.
This Gospel truth immediately and emphatically destroys any works of righteousness strongholds. And it is for this standard that we contend for the faith, and exhort the Church into right thinking about the Gospel truth. This convicting ministry; exposing, reproving, and proving wrong, operates through divine truth, not human force, and it centers on the gospel’s core realities. It's not something to be feared or ashamed of, not something you should apologize for. Nor should we boast in it. Instead we measure our work according to the Scriptures. Not as other men measure.
The world’s standards of "right" fall short; even the best fall short of God’s perfect holiness. We see it all the time. And this is why the God-given measure is always and ONLY the Spirit convicting people that true righteousness is imputed (credited) to believers by faith in His ascended son, Jesus Christ. No other measures can substitute for His ascendancy. Righteousness is available only because He went to the Father. Any boasting must be in the Lord alone (2 Corinthians 10:17), for approval comes from His commendation, not ours (v. 18).
This is why Scripture alone stands as the God-given standard. The Spirit works through the Word to convict, expose error, and reveal Christ. This is not a call to human boasting, intimidation, or worldly measures, Paul rejects those outright; but to humble reliance on divine truth that convicts without apology, measures without comparison to men, and commends only as the Lord does.
Have you ever wondered why those "super-apostles" (false teachers) didn’t go out and evangelize the unsaved, like Paul did in unreached areas?
Instead they targeted an already-established church, undermining Paul’s ministry and "infecting" it with their influence. The biblical text and context provide a clear answer: their actions reveal they were not truly serving the gospel but serving themselves, seeking personal gain, status, and control within an existing Christian community rather than advancing the kingdom into new territory. They masqueraded as legitimate ministers of Christ; using the right language about Jesus, the Spirit, and righteousness, but preached a "different Jesus," a "different spirit," and a "different gospel". They boasted in outward appearances, eloquence, and comparisons; and exploited the church financially. They truly were Vanity Fair, eclipsing devotion to Christ with wealth, status, titles, pleasures, and reputations. And when faithful Pilgrims of the Gospel Word pass through, they are mocked, beaten, caged, and sometimes martyred for refusing to buy into the merchandise or conform to the fair’s values.
In the Corinthian context, those "super-apostles" (false apostles) operated like elite merchants at the fair. Their "wares" were spiritual-sounding but worldly. Impressive eloquence, outward charisma, claims of superior apostleship, promises of elevated status or deeper "knowledge," and traditions, a gospel laced with self-commendation or works-righteousness.
Like Vanity Fair’s merchants, they disguised their true nature. They used the language of Jesus, the Spirit, and righteousness, but twisted it to serve personal empire-building, not Christ’s kingdom. And the false teachers thrived there because the environment rewarded showmanship, rhetoric, and status-seeking. They "made merchandise" of the church, building personal followings, extracting support, and turning believers into spectators of their "ministry" rather than disciples of Christ.
And this continues even today. They promise spiritual "upgrades" or prosperity while undermining the sufficiency of Christ’s imputed righteousness and the simplicity of the gospel. They complicate matters as doctors of doctrine and masters of debate. Building personal brands/followings through books, broadcasts, conferences, and online platforms. Promoting a "different gospel" that adds requirements (positive confessions, rituals, or moral performance) beyond faith in the ascended Christ.
The most prominent parallel is the prosperity gospel (also called Word of Faith teaching), which echoes the Corinthian errors by emphasizing material/spiritual "blessings" as evidence of faith, often tied to personal declarations or giving. But every single Christian denomination has an element of this spirit at work in its core. Christian teachers in this vein promise health, wealth, elevated purpose and status through the cause while downplaying suffering, weakness, or the sufficiency of Christ’s righteousness alone. They make faith into a force to "claim" blessings, turning prayer into demands rather than submission. They conplicate the gospel with layers of "keys," "principles," or "laws" that imply God’s favor depends on human performance. This directly attacks imputed righteousness by suggesting believers must add their own efforts to maintain or increase God’s blessings; creating strongholds of works-righteousness that the gospel demolishes.
These "doctors of doctrine" complicate what Scripture presents plainly. That salvation by grace through faith, not works (Ephesians 2:8-9), with righteousness is credited solely through the ascended Christ. And Paul didn’t ignore or apologize for these intruders; he exposed them as false apostles disguising themselves as servants of righteousness.
He guarded the simplicity of the gospel. He relied on the Spirit’s convicting work through the Word to expose error and reveal Christ. He measured leaders by their fruit, were they buying into their ministry to glom onto the work of another, to build empires on showmanship and self-promotion?
Friends, why do we contend for the Gospel Word of God?
Because the church (assembled believers) of Jesus Christ must remain vigilant against these Vanity Fair merchants, lest they turn the bride into a marketplace.
Instead, let’s boast only in the Lord, rest in His imputed righteousness, and proclaim the unadorned gospel that sets minds free from every false stronghold. This is the faithful path Paul modeled, and the one that truly advances Christ’s kingdom.
Heavenly Father,
We come before You in humble gratitude for the truth of Your Word, which alone stands as our measure and our hope. Thank You for the gospel of Your Son, Jesus Christ, the ascended Lord whose perfect righteousness is freely imputed to us by faith, nothing less and nothing more. By the power of Your Holy Spirit, convict the world of sin; especially the root sin of unbelief, convict us of true righteousness found only in Christ.
In the name of Jesus Christ, our ascended Savior and only boast, we pray.
Amen.
