The Foolishness of the Cross : and Yet the Power of God

Introduction

In 1 Corinthians 1:18 to 2:5, Jason Procopio opens the third week of the series on Paul's first letter to the Corinthians. The apostle tackles the root of that church's divisions: they had moved the cross of Jesus Christ out of the center of their attention and replaced it with philosophical wisdom and human teachers. Paul goes further than correcting the symptom. He shows that the cross does not merely save sinners; it dismantles every competing system of wisdom, status, and self-sufficiency. If you keep the cross at the center, your life will inevitably look absurd in the eyes of the world. And yet that is precisely where the true power of God is found.

Sermon Outline

1. The cross always divides humanity into two perceptions (v. 18-20)

• "The message of the cross is foolishness to those who are perishing, but to us who are being saved it is the power of God." One message, two radically opposed perceptions.
• The issue is never intelligence, reason, or logic. It is the spiritual orientation of the person listening. The cross is foolishness to those who are perishing, power to those who are being saved.
• Neutrality toward the cross does not exist. It is either rejected as absurd, or it completely redefines your reality.
• This was no accident. Quoting Isaiah 29:14, Paul shows that God had planned from the beginning to destroy the wisdom of the wise. Our elevated thinking has brought us much, but it has never led us to God.

2. God chose a salvation that looks absurd: a crucified Messiah (v. 21-25)

• Crucifixion was not primarily the most efficient method of execution. It was designed for shame. The condemned man; naked, nailed, hung up in public until he suffocated, forced to carry his shame even into death, reduced to absolute weakness.
• Christianity claims that our Savior, the creator of the world, was condemned as a blasphemer and crucified. From the outside, this is a ridiculous message: our hero lost, he was defeated, he was publicly humiliated.
• The Greeks seek philosophical wisdom. The Jews seek a miraculous sign, a Messiah after the pattern of King David who conquers enemies and makes the kingdom prosper. A crucified Messiah is a scandal to some and foolishness to others.
• This is still the reason why many go astray today. They come to faith for the experience, for the signs, for what God can do for them. But a ministry based on experience can never produce saving faith. Only those whom the gospel has saved grasp the true power of the gospel.

3. The very makeup of the church proves the message of the cross (v. 26-31)

• "Consider your own calling, brothers and sisters. Not many of you were wise by human standards, not many were powerful, not many were of noble birth."
• God deliberately fills his churches with ordinary human beings, people the world will not find impressive. This is not an accident; it is intentional.
• On two levels, God shames the wise and the strong. First in Christ himself, who appeared weak and despised. Then in the church, in an eschatological sense: when Christ returns to judge the world, the powerful who relied on themselves will be revealed as weak, and the ordinary people who placed their faith in Christ will stand firm.
• No human being can boast before God. The only thing you can boast in is God himself: "He became for us wisdom from God, our righteousness, our sanctification, and our redemption."

4. Paul's ministry displays the same weakness (2:1-5)

• Paul did not come to Corinth with superiority of speech or wisdom, even though he was capable of it. He resolved to know nothing among them except Jesus Christ, and him crucified.
• "I was with you in weakness and in fear and much trembling." The messenger matched the message.
• The demonstration of the Spirit and of power that Paul speaks of is not primarily visible in miracles. It is visible when someone hears this absurd message and, instead of rejecting it, says: "This is true. It doesn't make sense, but I know it's true." That conviction comes only from the Holy Spirit working within.
• Result: a faith that does not rest on human persuasion, but on the power of God.

Key Takeaways

• The cross does not merely save sinners. It dismantles every competing system of wisdom, status, and self-sufficiency.
• The cross necessarily divides humanity. There is no possible neutrality: it is either foolishness or the power of God.
• This is not a matter of intelligence but of spiritual orientation. No one is saved because they are smarter; everyone is saved by the power of the Holy Spirit who opens the heart.
• A church shaped by the cross will look strange and unimpressive, filled with ordinary people. But that is exactly where the true power of God is displayed.
• If you still feel the need to prove yourself, the cross is not truly at the center of your life. Christ's finished work sets you free from having to impress anyone.

Personal Application

1. Before whom, this week, do you still feel the need to prove yourself? What does that reveal about the real place of the cross in your life?
2. Do you seek God first for what he can do for you (solving a problem, giving you an experience, giving you a sign), or for what he has already done at the cross?
3. When you tell someone about the gospel and they find it absurd, what is your reaction: trying to "update" the message so it goes down easier, or continuing to proclaim the cross clearly while depending on the Spirit?
4. Look around you in your church. Do you thank God for filling it with ordinary people, or do you wish it were more impressive, bigger, more visible?
5. In what area have you added something to the cross (your performance, your service, your spiritual experience) as the foundation of your confidence before God?

Frequently Asked Questions

Why is the cross called foolishness in 1 Corinthians 1?

Because crucifixion was not primarily a method of execution; it was designed for shame. The condemned died naked, nailed up, in public, in the most absolute weakness. To claim that the Savior of the world was crucified is to proclaim that our hero lost and was publicly humiliated. To a mind seeking philosophical wisdom (like the Greeks) or a sign of power (like the Jews), this announcement seems absurd. It becomes the power of God only for those whom the Spirit opens to the truth.

How do I know if the cross is truly at the center of my Christian life?

A good indicator, Jason Procopio points out, is your need to prove yourself. If you still feel the need to be impressive, exceptional, convincing, then the cross has not yet truly redefined your identity. A life shaped by the cross no longer seeks to prove itself, because Christ has already accomplished everything. Your wisdom, your righteousness, your sanctification, and your redemption do not come from you. They come from him.

Why did God choose a church filled with ordinary people?

Because the very makeup of the church is meant to prove the message of the cross. If God filled his churches with presidents, prime ministers, philosophical geniuses, and powerful personalities, we might think it was our own strength that saved us. Instead, he deliberately chooses people the world does not find impressive, so that no one can boast before him and the glory goes entirely to Christ.
