Our Eternal Solution (1 Corinthians 1:18-25; LD 6)

Introduction

We know that we are in deep trouble. Adam had the chance to do what was right, and he failed to do it. The problem is that we can only dig the hole deeper. We think that credit card debt is bad, but our debt is far worse. Our debt will never go away, even in death. We can't out-work it, out-live it, or out-think it. So our problem is very severe and beyond overwhelming. Lord's Day 6 of the Heidelberg Catechism helps us to see the eternal solution. Only God can implement this solution.

Sin's Problem: We Need a Mediator

The catechism reminds us that we need a mediator. The very thought of a mediator means that something has gone wrong. A mediator means two parties are at odds. The very introduction of the concept of a mediator introduces an admission of our guilt. God is 100% righteous. We are 100% at fault. There is no way we can work to please God when we are 100% in debt. There is no payment plan.

And the mediator's task is staggering: take people who have fully offended a perfect God and bring them into his presence as fully righteous. This is the greatest laundering effort ever in history! In fact, it is not hiding dirty money, but fully redeeming it to remove all controversy that surrounds it.

Our cleansing requires someone who is both truly human (because it was humanity that offended God) and truly God (because no mere human can bear an infinite, eternal penalty and survive it). A human enduring his own sin would be in hell forever and never get out. There is no way that a person could pay the debt on behalf of another. This is why we need a person who is divine to endure an eternal punishment. The person also has to be human to stand in the place of the creature that offended.

Only a divine person united to a human nature can absorb eternal wrath in a moment of time. Only Christ is such a mediator.

God's Solution: The Folly of the Cross

Paul addresses a church drunk on elitism. They love their gurus. They love how they can flaunt their spiritual gifts. Ironically, Paul, who had every credential to out-elite them all, goes straight to the cross. He does not call his accomplishments to their attention as he does in Galatians. No, he goes straight to the cross.

That's a jarring move, because the cross was not a sentimental symbol like we make it today. No, the cross is a declaration of shame. In Roman culture, crucified criminals weren't even officially recorded. In Jewish culture, to be hung on a tree meant you were a covenant breaker, cursed by God. When the disciples watched Jesus die on the cross, they had every reason to think they'd been deceived. In their mind, God declared a messianic fraud who transgressed God’s holiness.

Paul knows all of this! He preaches it anyway. Why? Because the "foolishness" of the cross is precisely the point. Christ, who never broke the covenant, was publicly displayed as though he had, and that is why we need him. And because death could not hold him, the resurrection vindicates him completely. At Christ's weakest moment, he won the greatest victory. Worldly wisdom missed the cross. The Jews demanded signs and missed the sign of the cross. The Greeks sought wisdom and missed the wisdom of God standing right in front of them.

Thus, the wisest people of this age did not see the wisdom of the cross. This is why Paul calls attention to the cross. If we do not see the wisdom of God’s plan, then we will not see redemption.

God's Proclamation: The Gospel Must Keep Being Preached

Knowing the facts about Christ isn't enough on its own. Calvin puts it plainly: as long as Christ remains outside of us, he is of no benefit to us. The work of Christ has to become our work. The Lord uses Gospel preaching that lays out Christ’s cross to bring his people into their new relationship with Christ.

The Corinthians had witnessed extraordinary manifestations of the Spirit, and probably interviewed eyewitnesses of the resurrection. However, Paul still keeps going back to the gospel. This message is not a one-and-done message. It is a message that is continually preached, and we continually need this message.

The catechism traces this same pattern across all of redemptive history: the gospel was announced in Genesis 3:15, repeated to the patriarchs, foreshadowed in every sacrifice and ceremony, proclaimed by the prophets, and fulfilled in Christ. Generation after generation, God's people were sustained by this same message. It was repeated and repeated because we so easily forget Christ’s message. We fail to see that without the gospel message, we have nothing.

The cross of Christ is the message that Christ had to suffer for an insufferable people. We are such people.

We don't outgrow the gospel. We need to hear it continually, because it is the ongoing means of grace by which God keeps his people alive and moving toward glory. It is in Christ, going to the cross, that God’s wisdom is shown. It is in the cross that Christ is ultimately vindicated in his resurrection and ascension. His work was so perfect that the heavenly courts vindicated him.

Conclusion

So how do we solve our unsolvable, eternal problem? We don't. We can't. But God has.

He sent his Son. His son, who is fully God, fully man, stands in our place as the covenant breaker. We transgressed, but Christ did not. Christ bore what we deserved, was raised to prove he'd conquered it, and now the gospel goes out as the living word that unites us to him. The world will call it foolishness. Paul's response: “Fine. Call it folly. In that folly is life.”

So let us not be ashamed of the Gospel. Let us keep hearing, submitting to the preaching, and clinging to the substance of the message: Christ. Let us exude the joy that we have been redeemed by the living God. That is our significance, our credibility, and our only boast is in Christ. Let us find it there, and live in it. Amen.
