I.                  Introduction

If you’re my age or older, you’ve seen our culture shift quite a bit on its view of Christianity.  Aaron Renn noted that, while the culture was largely positive toward Christianity before 1994, it became neutral toward it afterward, and then negative toward it post-2014.[1]  This means that we remember when the church was respected in America, when we had a voice in the public square, and we’ve seen that change.  We live in what many Christians accept now as “negative world,” and many debate how we should engage culture and evangelize.

For instance, many Christians suggest that we now “contextualize” the gospel message for this age.  This method seeks to tailor the gospel to current audience by building bridges and finding common ground.  This means making the message relatable and less intimidating, perhaps weaving in contemporary issues like social justice or personal fulfillment into gospel presentations. 

If you’ve heard of remaking movies for “modern audiences,” you might have an idea of what the issue is here.  While this can effectively draw people in, it risks diluting the gospel, sometimes prioritizing cultural relevance over the stark truth of sin, repentance, and the cross.  It also relies on human effort to make the gospel attractive rather than trusting the Spirit’s work through the proclaimed Word.

In contrast, we have what is sometimes called the “presuppositional” approach.  This evangelistic method begins with the conviction that the Bible is the ultimate authority and that all human reasoning, morality, and meaning depend on God’s truth.  This approach lovingly challenges the wisdom by which unbelievers operate, their presuppositions, exposing the inconsistencies of their worldviews while pointing to Christ.  For instance, a presuppositional evangelist might ask an unbeliever how they justify morality or knowledge without God, using such questions to reveal the necessity of God’s revelation.  

The reality is that unbelievers are naturally resistant to Christian truth, whether or not they view it as a net positive or a negative for culture.  Even when culture looks down upon Christianity, as the Corinthian culture did, believers must continue to preach the message of the cross with no worldly additions.  Yet, because of their divisions, some Corinthian Christians wrongly tried to impress the unbelieving Jews, and others were trying to impress the unbelieving Greeks.  They were trying to build bridges, but sin twists human reason and messaging.  Human wisdom according to the world is not God’s wisdom, and God even keeps the two separate in the name of holiness.

We don’t want to inadvertently shift focus from the gospel’s content to the messenger.  Instead, we trust that the Holy Spirit works through the Word to convict and to convert, even when it appears foolish to the world.  That’s what we see as we delve into this passage, as Paul emphasizes on the cross’s power over human words and strategies.

If we are to evangelize our age, then we need to understand this.  There is only one power that can change hearts and minds in this world, and it is the message of the cross.  In this passage, we will note both the strength of the Word (vv. 18–21) and the superiority of the Word (vv. 22–25).  Let’s consider the central message we should communicate as we evaluate this together.

II.              First, the Strength of the Word (vv. 18–21)

For the word of the cross is foolishness to those who are perishing, but to us who are being saved, it is the power of God.  For it is written, “I will destroy the wisdom of the wise, and the cleverness of the clever I will set aside.”  Where is the wise man?  Where is the scribe?  Where is the debater of this age?  Has not God made foolish the wisdom of the world?  For since, in the wisdom of God, the world through its wisdom did not come to know God, God was well-pleased, through the foolishness of the message preached, to save those who believe.

Paul just said that Christ didn’t send him “to baptize, but to proclaim the gospel, not in wisdom of word, so that the cross of Christ will not be made empty” (1 Cor. 1:17).  The message of the gospel (which is the message of the cross) is more important than baptism, and Paul goes on here to say that it’s also more important than human wisdom.  Sinful people will see it as foolish, but it is true wisdom.

That’s ironically why it’s so important to proclaim “the word of the cross” or the “message” (NET, HCSB).  This is, as the MacArthur Study Bible notes, “God’s total revelation, i.e., the gospel in all its fullness, which centers in the incarnation and crucifixion of Christ (2:2); the entire divine plan and provision for the redemption of sinners, which is the theme of all Scripture, is in view.”[2]  Of course, this message divides us between believers and unbelievers,[3] which Paul expresses in this verse.

Consider first “those who are perishing.”  They are currently traveling a path to eternal destruction, and their choices everyday give evidence of this spiritual death.  As such, this message appears as “foolishness,” a term from which we derive the term “moron.”[4]  Indeed, the unsaved, certain of their superior thought process, have names for Christians!  We’ll talk more about why they think this way in a few minutes, but, at the heart level, though, they don’t want this message because the word of the cross cuts to the heart of self-centeredness, demanding self-renunciation and obedience (cf. Mark 8:34–35; 2 Tim. 2:12).[5] 

Paul contrasts this position to “us who are being saved.”  Here, Paul includes himself and the Corinthian believers and with all who would believe.  Note that salvation isn’t only something accomplished in the past, but it is also an ongoing reality, a divine work in process — initiated at conversion, advanced through sanctification, and consummated in glorification (cf. Rom. 8:23; 13:11).[6]  The present tense underscores certainty: God is actively saving His people.

For those in this category, the word of the cross is “the power of God.”  This power is not mere intellectual assent but transformative.  It is the power to turn sinners into saints, and to clean our messes in holiness.  The word of the cross only has power for believers, though.

This brings us to a sobering thought: Some people will hate our message.  So, are we reacting by trying to dilute the message with worldly appeals, or are we being faithful?  There are some who want to shave off the rough edges, those like Joel Osteen who won’t talk about sin or Tim Keller who wanted to avoid anything “too political.”  The message will divide, so let it do its work.

In v. 19, Paul substantiates his point by quoting Isaiah 29:14.  It’s always worth noting how often the New Testament invokes scriptural authority, a fitting example in this context.  And, in Isaiah’s context, God warns Judah's leaders against relying on human ingenuity amid threats from the Assyrians.  After all, their “wisdom” and “cleverness” — which the Spirit uses ironically here — will be thwarted by God.  Of course, this prophecy finds ultimate fulfillment in Christ’s kingdom (Rev. 17:14), where all human wisdom perishes,[7] but it also illustrates present, divine intervention — like when God destroyed 185,000 Assyrians with one angel (Isa. 37:36; 2 Kings 18–19).[8]  Another example of this is in the Book of Daniel, where God repeatedly shows His power over the wise and clever men.  Only God’s chosen are capable of having success when they follow what He has said.

God’s word is able to accomplish what man cannot.  So, this warns us not to elevate our human intellect over His revelation.  As believers, we must proclaim the cross without apology, trusting God to dismantle pretentious wisdom.  God’s ways will confound the proud to and exalt the humble.

So, in v. 20, Paul unleashes four rhetorical questions,[9] dripping with sarcasm, which show how much stronger and wiser God’s word is.  First, he asks, “Where is the wise man?” — a possible general reference to Greek philosophers who had persuasive speech.[10]  One commentator notes

some catch-phrases in the popular philosophy of the day: ‘The wise man is king’ and ‘To the wise man all things belong’.  Paul rejected this worldly wisdom.  He also rejected the form in which much of it was purveyed, i.e. with persuasive eloquence.  ‘The Greeks were intoxicated with fine words.’  Rather like many in Oxford University today, they were concerned not so much with the truth or otherwise of what was said, as with the articulacy and cleverness with which it was said.[11]

Similarly, Paul calls out the scribe.  This often refers to Jewish experts in the Mosaic law.[12]  This would parallel his Jew/Greek distinction in this passage.

Next, Paul asks about the “debater of this age.”  These would be those who might be skilled at arguing philosophy[13] or rhetoric.[14]  The Reformation Study Bible notes that it’s unclear how precise Paul wants these categories, but it seems like there is plenty here to highlight the great thinkers both in the Jewish faith as well as in Gentile Corinth.

That leads to Paul’s big question — “Has not God made foolish the wisdom of the world?”  He frames this question to expect a resounding “yes!”  He’s saying that God has already “made foolish” (as a past action) worldly wisdom.  The question is whether we believe this and submit our wisdom to the cross.

In fact, God’s wisdom takes us on an unexpected path, as v. 21 explains.  God’s wise design ordained that “the world through its wisdom did not come to know God.”  If we think we can argue people to God, we’re mistaken, and they’re just as mistaken if they think they can argue themselves there.  As one study notes, this “would exalt man, so God designed to save helpless sinners through the preaching of a message that was so simple the ‘worldly wise’ deemed it nonsense.”[15]  Human wisdom — philosophy, science, debate — fails to reach God.

Though the Greeks thought their wisdom could get them closer to God, it is not possible.  Similarly, some today think they can know God though enough scientific knowledge.  As T. S. Elliot wrote in the opening stanza of “Choruses from ‘The Rock:’ ”

Knowledge of words, and ignorance of the Word.
All our knowledge brings us nearer to our ignorance,
All our ignorance brings us nearer to death,
But nearness to death no nearer to GOD.

Yet, there is good news.  We read that God “was well-pleased” — a term of divine delight — to save believers.  How?  It’s through the foolishness “of the message preached.”  Of course, Paul uses the term “foolishness” sarcastically, for he’s already identified this as the wisdom of God.  There’s a message of good news for any who would humble themselves to believe some holy nonsense!  And this salvation is where we see the power of the word most clearly.

Note, though, that salvation comes only to “those who believe.”  This is a continual blow to human pride as God uses the “low” and the “simple” to save.  This empowers preachers and evangelists, though — we have what we need.  We may feel like it’s not enough for the lost world’s questions, but it’s all that’s needed.

In summary, these verses reveal the strength of the Word.  It divides, it destroys worldly wisdom, and it delivers salvation through faith.  Let us trust its power in our witness, for there’s nothing better.  And that brings us to the next point:

III.           Second, the Superiority of the Word (vv. 22–25)

For indeed Jews ask for signs and Greeks search for wisdom, but we preach Christ crucified, to Jews a stumbling block and to Gentiles foolishness, but to those who are the called, both Jews and Greeks, Christ the power of God and the wisdom of God.  Because the foolishness of God is wiser than men, and the weakness of God is stronger than men.

Unbelievers always have reasons they reject the gospel, and these are sometimes cultural barriers; Paul identifies two that were pressing at the church of Corinth.  First, he says that “Jews ask for signs.”  In other words, they wanted (or demanded) attesting miracles as proof of authority (cf. Matt. 12:38; Mark 8:11–12).[16]  Of course, this didn’t stop them from rejecting the signs of Christ.[17]  Part of the problem was that they expected the Messiah to be a victor over Rome while Jesus was crucified, meaning that He couldn’t be the Messiah.[18]  This excuse from the Jewish leadership, while seeming logical, was convenient considering how they had participated in Christ’s crucifixion.  Still, this would become a major talking point for 2,000 years of future generations, where Jesus’s death was seen as a curse (cf. Deut. 21:23).

One commentary notes an example of this:

In the second century, in Justin Martyr’s Dialogue with Trypho 31–32, Justin attempts to convince Rabbi Trypho that Jesus is the Messiah with reference to Daniel 7, and Trypho responds: ‘Sir, these and such-like passages of scripture compel us to await One who is great and glorious, and takes the everlasting Kingdom from the Ancient of Days as Son of Man. But this your so-called Christ is without honor and glory, so that he has even fallen into the uttermost curse that is in the Law of God, for he was crucified’ (cf. Deut 21:23).[19]

Paul then notes that “Greeks search for wisdom.”  This doesn’t mean that no Jew wasn’t also interested in wisdom, but wisdom was an interest for the Greeks.  They wanted whatever ideas were new (cf. Acts 17:20–21) and worshiped the goddess of wisdom.[20]  And when they thought of a supreme God, they viewed Him as apathetic to and untouched by suffering — making a crucified God absurd.[21]  As another commentary notes:

The second-century philosopher Celsus, who made a career out of attacking Christianity, wrote, ‘God is good and beautiful and happy, and if in that which is most beautiful and best, if then he descends to man it involves change for him, and a change from good to bad, from beautiful to ugly, from happiness to unhappiness, from what is best to what is worst, and God would never accept such a change.’  The idea of the incarnation, not to mention the crucifixion, was utter folly to Greek thinking.  To those rationalists nothing could be more absurd than the idea of an incarnate God giving Himself to be crucified in order to secure salvation, holiness, and eternal life for a fallen world.[22]

What do we do when we encounter such barriers?  Sometimes, there are certain ministry “gurus” who talk about “contextualizing the message” to make it more palatable.  There are churches changing hymns because talk about the cross and the blood of Christ might be too offensive for some people’s sensibilities.  Perhaps there’s a clever way to alter the message and then get more converts at the altar.

However, in v. 23, Paul says, in defiance, “we preach Christ crucified.”  This is Paul’s sole message (2:2).  He acknowledges that it is a “stumbling block” to Jews, and “foolishness” to Gentiles.  Instead of contextualizing the message, we should just be faithful and expect rejection.  The cross offends pride, even that of Christians, at times.  The Corinthians will need some humility moving forward through their issues.

Yet, again, there is good news.  V. 24 gives us a turning point: “But to those who are the called, both Jews and Greeks, Christ the power of God and the wisdom of God.”  Note that we find both power and wisdom in Christ.  It’s just that it’s only there for believers.

Consider this: Believers are identified as those who are called.  This isn’t a general call, like Charlie Kirk spoke into a microphone and accurately said Jesus died for sinners.  That call must then be followed by the call of the Holy Spirit within us, replacing our hard hearts for those which are alive.  When God calls us, whether we’re Jewish or Grecian in our former thinking, we know that we’re the sinners for whom Christ died, and we’re the ones in need of redemption.  Suddenly, we realize we need to believe this message, which we now see as powerful and wise!

Paul then uses a bit more sarcasm to drive this point home in v. 25.  He first mentions the “foolishness of God” — but, of course, there is no foolishness there.  Yet, the cross in human eyes is moronic, so Paul says it’s actually “wiser than men.”  Similarly, if God has any weakness, that is “stronger than men.”  In other words, God has more power in His pinky than we have in our whole bodies! 

Of course, that brings us back to humility.  God’s wisdom and ways are superior.  It is up to us to bow to them, even if you don’t understand everything right now.

IV.           Conclusion

Remember, this is in the wisdom of God.  We are not going to argue people into the kingdom, for they could be argued back out of it.  We can’t show convincing enough proofs, for other people will show them signs that will lead them astray.  The problem is the hardness of heart due to sin, and the only solution to that is the message of the cross.

That doesn’t mean that we don’t ever engage in arguments for the sake of leading people to Christ.  This same Apostle Paul engaged in a rhetorical defense of the faith on numerous occasions.  There are times for debates and apologetics, and I can recommend examples to you of those who have done it well.  Still, remember the real problem is sin, meaning the real solution is the gospel.  This will keep us from focusing on our ability and instead trust in the power of the Word to accomplish its divine purposes.
