Predicazioni/Matteo/Costruire sulla Roccia/English version
We live in an age where scientific and technological progress coexist with wars, crises, and profound uncertainties regarding humanity's future. Why does it seem that people never learn from the lessons of history? Jesus concludes the Sermon on the Mount with the parable of the two houses, showing that the fundamental issue is not the violence of the storms, but the foundation upon which we build our lives. This reflection considers how God, in His Providence, uses the trials of life and history to call us to build upon the only Rock that never fails: Christ—heeded and followed in the obedience of faith.
Building on the Rock
Introduction: The Lessons of History
We live in an extraordinary age. Humanity has never possessed so much scientific knowledge, so many means of communication, so many technological possibilities, or such material prosperity—though not for all. Yet, alongside these advancements, we continue to witness wars, injustices, violence, divisions, and new forms of fear. In recent months, there has even been renewed and anxious talk of the imminent risk of nuclear conflict. One cannot help but ask: Is it possible that humanity never learns from the lessons of history?
Many thinkers have sought to answer this question. Some attribute society’s failures to economics, others to politics, still others to culture or institutions. All these analyses contain elements of truth and deserve respect. As Christians, we do not believe that those who do not share our faith are incapable of understanding important aspects of reality. However, the Bible invites us to go even deeper and ask a different question: What does God want to teach us through history?
When we read events in the light of faith, we discover that history is not merely a random succession of events, nor is it simply the result of human decisions. Scripture teaches us that God continues to govern the world with His Providence. At times, He educates His people and calls humanity to account precisely by allowing the consequences of the choices on which individuals, peoples, and civilisations have built their existence to come to light. The storms of life and history do not create the foundation on which we have built; they reveal it.
With this perspective, we can better understand the words with which Jesus concludes the Sermon on the Mount—the parable of the two houses. It is not merely an invitation to personal prudence. It is a call to continually examine the foundation on which we are building our lives, our families, our communities, and even the society in which we live. The storms will come for everyone. The decisive question is not if they will come, but whether, when they do, they will find a house built on sand or on the Rock.
The Parable of the Two Houses
Let us listen to this Gospel text and ask ourselves what Jesus wants to say with this parable—to me, to our Christian communities, and to the world:
"Therefore everyone who hears these words of mine and puts them into practice is like a wise man who built his house on the rock. The rain came down, the streams rose, and the winds blew and beat against that house; yet it did not fall, because it had its foundation on the rock. But everyone who hears these words of mine and does not put them into practice is like a foolish man who built his house on sand. The rain came down, the streams rose, and the winds blew and beat against that house, and it fell with a great crash." (Matthew 7:24–27)
I. Everyone Builds—But on What Foundation?
Jesus does not contrast a hardworking person with a lazy one. Both men build a house. Both hear His words. Both desire security and stability. The difference does not lie in effort, intelligence, or even religiosity. The difference is entirely in the foundation. One house is built on rock, the other on sand.
We, too, are all builders. We build our lives, our families, our work, our relationships. Christian communities build their testimony. Nations build institutions, economic systems, cultures, and political orders. No one lives without building something. This is why Jesus’ question is universal: On what foundation are we building? When the storm comes, will what we have built withstand it?
Here, the Master surprises us. We might be tempted to look first at the building: how large it is, how beautiful, how efficient it seems. But Jesus looks at what no one normally sees: the foundation. Foundations are hidden, yet they decide the destiny of the house. The same is true in personal life and in the history of peoples. Great civilisations, like individuals, may appear solid and promising. They may accomplish extraordinary works and pursue noble ideals such as justice, freedom, or peace. The problem is not necessarily the building; the problem is the ground on which it is built.
II. The Storms Reveal the Foundation
The parable contains a detail that often escapes us. Jesus does not say that the house built on the rock will be spared from rain, streams, and winds. The storm strikes both houses. The difference is not in the intensity of the trial but in its outcome.
This corrects a mistaken idea that sometimes creeps in even among Christians. Faith does not shield us from all of life’s difficulties. Even those who build on the Rock experience pain, illness, disappointment, trials, and even persecution. Being disciples of Christ does not mean living a life without storms; it means having a foundation that endures when the storms come.
This observation applies not only to personal life but also to the history of peoples. Nations endure wars, economic crises, social conflicts, cultural changes, periods of prosperity and decline. Every generation faces its own storms. We ourselves live in days when the world seems to be traversed by ever more serious and unpredictable tensions. Many wonder where humanity is heading and whether it has truly learned anything from the tragedies of the past.
The Bible invites us to look at these events with a different gaze. Without claiming to interpret every single event as a particular judgment of God, we know that nothing escapes His Providence. God continues to govern history, and at times He allows men, peoples, and civilisations to experience the consequences of the foundations on which they have built. It is a form of education, sometimes severe, but always aimed at calling humanity back to the truth.
This is why storms also have a revealing function. As long as the sky is clear, the two houses appear equally solid. Only when the rain, streams, and wind come does the difference become apparent. Trials do not create the foundation; they expose it. Storms do not determine the solidity of the house; they reveal it.
This is also one of the great lessons of history. Civilisations that seemed unshakable have collapsed. Political systems that promised a radiant future have shown deep contradictions. Even the most prosperous societies have suddenly discovered their fragility. Not because every project they undertook was wrong, but because no human construction can endure if it claims to replace the foundation that only God can provide.
III. Building on the Rock
At this point, the parable places a very personal question before us. It does not first ask us to judge others. It does not invite us to identify which are today’s "houses built on sand." Instead, it asks: On what are you building?
It is significant that Jesus does not simply say, "Whoever hears these words of mine." He says, "Whoever hears these words of mine and puts them into practice." The difference between the two builders does not lie in whether they have heard or not. Both hear. Both know the Word. Both know how one ought to build. What distinguishes them is obedience. The Rock, therefore, is not a religious theory. Nor is it even correct doctrine taken in isolation. It is Christ Himself, received in faith and followed in daily obedience. This is a decisive difference. For one can even know the Gospel without truly founding one’s life upon it.
This word also challenges our Christian communities. It is easy to read this parable and think about the world’s problems. It is much harder to let it question us. Are our communities truly building on the Rock? Or do they sometimes build on tradition, habits, organisation, prestige, numbers, or human abilities? All these things can be useful. None of them, however, is the Rock. The Rock remains Christ. This is why the Church must continually reform itself by confronting itself with His Word.
This also introduces a healthy humility. The apostle Paul writes: "No one can lay any foundation other than the one already laid, which is Jesus Christ" (1 Corinthians 3:11). Then he adds something we often forget: even what we build on that foundation will be tested by fire. This word concerns us first and foremost. Being Christian does not make us immune to error. It does not authorise us to look down on the world from on high. We, too, are continually called to examine what we are building. We, too, must allow ourselves to be corrected by the Word of God.
Precisely for this reason, Christian testimony cannot be reduced to silence. Paul writes to the Ephesians: "Have no fellowship with the fruitless deeds of darkness, but rather expose them." To expose does not mean adopting an attitude of moral superiority. It means loving our neighbour enough to tell them the truth. If I see someone building a house on sand and remain silent, I do not love them. Christian denouncement always arises from charity. It does not merely say, "There is danger here." It also says, "Come. There is a foundation that will not collapse."
And perhaps this is the task of Christian communities in our time. Not to predict the future. Not to identify every crisis as a particular judgment of God. Not to support this or that ideology. Their task is much simpler and, at the same time, much more demanding. They must show that there is a different way to build. A community where truth walks alongside love. Where authority becomes service. Where freedom is accompanied by responsibility. Where forgiveness breaks the spiral of hatred. Where the Christ proclaimed in the New Testament truly remains the foundation. This is the house the world should be able to see.
Conclusion: Building on the Rock
Let us return, then, to the question with which we began. Humanity seems never to learn from the lessons of history. The Christian faith, however, invites us to look even deeper. God continues to speak through history, and in His Providence, He sometimes allows men, peoples, and civilisations to experience the negative consequences of the false foundations on which they have built. Not because He desires their ruin, but because He calls them to build on the only foundation that can sustain life.
This call concerns us first and foremost. Building on the Rock does not simply mean declaring ourselves Christians. Jesus says: "Whoever hears these words of mine and puts them into practice." The Rock is Christ, but building on Him means living as His disciples: conforming our lives daily to His Word, allowing ourselves to be guided by the Father’s will, learning to live according to the Father’s will, as Jesus taught and embodied it in His life—that is, lived in the spirit of love, justice, and mercy that we see in the Lord Jesus. It is a journey of continuous conversion, not the possession of a perfection already attained.
This concerns our personal lives, the way we work, how we manage what God entrusts to us, how we treat our neighbour, and how we face trials. It concerns our families and our Christian communities, called to be places where the Gospel is not only preached but lived. And it concerns our presence in the world. Christians are not called to flee from society but to serve it, showing in word and deed that there is a different way to build human coexistence, founded on truth, justice, responsibility, and love.
Precisely for this reason, Christian communities cannot remain silent. The apostle Paul urges us not to participate in the fruitless deeds of darkness but to expose them. We do not do this to feel superior to others or to defend a particular ideology. We do it because we love our neighbour. Whoever sees someone building on sand and remains silent does not love them. Christian testimony does not limit itself to denouncing what leads to ruin; it also points, with humility and hope, to the foundation that will not collapse.
Jesus concludes the Sermon on the Mount not with a threat but with an invitation. The storms will come for everyone. No one can avoid them. But whoever hears His Word and puts it into practice will discover that there is a foundation that no trial of life, no crisis of history, and not even the final judgment can destroy. Let us, therefore, build on the Rock, for only in Christ can our lives, our communities, and even our service in the world find a stability that endures forever. Let us build on the Rock by hearing His Word and putting it into practice. For only then, when the rain, streams, and winds come, will the house remain firm.
Prayer
Let us pray.
Lord God, our Father, we thank You that, in Your patience and Providence, You do not cease to speak to us. You call us through Your Word and often through the lessons of life and history. Forgive our folly when we trust in our own strength, our own securities, or the works of our hands more than in You. Grant us to build our lives on the only foundation You have laid, Jesus Christ, our Lord. Give us a teachable heart, one that does not merely hear Your Word but desires to put it into practice every day. May our families and our Christian communities truly be built on the Rock, so that they may endure in trials and bear witness to the faithfulness of Your love. Make us humble and courageous witnesses in the world. Free us both from the silence that springs from fear and from the pride that judges without loving. Grant us the wisdom to discern what leads to life and what leads to ruin, and the charity to always point people to the hope that is found in Christ. And when the storms of life come, sustain us with Your Holy Spirit, so that our faith may not fail and, persevering to the end, we may glorify Your Name and faithfully serve Your Kingdom. Through Jesus Christ, our Lord. Amen.
