Jesus Warns You: Two Foundations, One Future

Introduction

The preacher admits something about herself right away: she's not the best person to invite to a horror movie. Not because she's scared, but because she has a habit of talking to the screen. When she sees people doing something stupid, she needs to shout "Watch out!", even knowing they can't hear her. There's a reflex in her to warn people before the worst happens.

This habit, she says, is part of how our world works. There's even a legal duty to warn someone in danger: warning people is human, and it's Christian. And that's exactly what she loves about the Lord: "he doesn't shy away from the facts; he is always faithful to warn us about the real dangers." In the last short paragraph of the Sermon on the Mount, Jesus tells a story to warn you. He uses the language of a sage, full of metaphors, to put you face to face with real dangers that carry eternal consequences. This article invites you to stop and sit with these words.

Message Outline

1. Jesus puts a choice in front of you

• The preacher reads Matthew 7:24-27: "Everyone therefore who hears these words of mine, and does them, I will liken him to a wise man, who built his house on a rock… Everyone who hears these words of mine, and doesn't do them will be like a foolish man, who built his house on the sand."
• "First of all, Jesus puts a choice in front of us." It's a very vivid story, but there's a choice at its heart. Door number one: hear the Word and put it into practice. Door number two: hear the Word and neglect it. And two completely different endings.
• Jesus, like any good speaker, leaves people with a choice. It's how he closes his sermon. And all through Scripture, you find this same kind of choice, sometimes with very similar imagery. The preacher points to Psalm 1: the one who meditates on the law of the LORD day and night is like "a tree planted by the streams of water, that produces its fruit in its season, whose leaf also does not wither" (Psalm 1:3).
• The secret? "He doesn't walk in the counsel of the wicked, he doesn't stand on the path of sinners, but he loves the Word", and so his life is solid. "Exactly like what Jesus describes when he talks about someone who builds his house on a rock. It's solid."

2. Hearing and doing the Word: a solid life

• The people hearing Jesus for the first time understand the image perfectly. These are people who live off the land, who depend on their trees and their fruit. Building their houses is simple work. Water and a good foundation are essential for both projects to succeed.
• But Jesus introduces something new compared to the psalmist: both houses get hit by the rain, a rising flood, the winds. In other words, the trials of life.
• The preacher draws on Saint Augustine, who describes these trials this way: evil compared to the darkness of superstition, the rumors of men to the wind, the flood to the lust of the flesh. "He who has his house founded on the rock fears none of these things. That is, he not only hears the command but does it too."
• In practical terms: sometimes we hold onto ideas that don't hold up, and when reality catches up with us, it's like a flood. When people slander us, talk behind our back, those are terrible winds beating against our door. When we suffer the consequences of our own foolishness, our own sin, that really does feel like a flood closing in on us.
• But for the person who builds their life on the words of Christ, there's something that helps. His Word. Take slander on social media. Without the words of Jesus already read in Matthew 5:21-22, "Whoever is angry with his brother without a cause shall be in danger of the judgment", it's very hard to arrive at forgiveness or let go of the anger. What's most natural is to feed it, grab your phone, and go on the attack.
• When you're caught in a really precarious situation, it's very hard to stop and not worry. Without "Consider the birds of the sky… See how the lilies of the field grow" (Matthew 6:26-28), nothing stops you. Picture the most hardened atheist you know: you can be sure that when he's anxious, he isn't telling himself, "ah yes, I need to go look at the birds or the flowers." Without Christ, that reflex is absolutely absurd. With Christ, you have the Creator of heaven and earth behind you, able to change anything. And you know that because you know his Word.
• "The word of Christ supplies a power and a perspective that go beyond our own strength, a perspective that carries us all the way to our last day and into eternity with confidence."

3. Hearing and neglecting: the ruin that follows

• Two men. They heard the same words. They built the exact same kind of house. But the results are very different. People often push back on this by saying: "sure, but still, people who don't follow Christ have a lot more fun."
• The preacher recounts a crisis of faith a student once shared with her: "Jesus wants to give me an abundant life, but clearly, if I want to live a happy life, I need to do whatever I want." Yes and no. Sin is like a loan; a very bad loan: sure, you can spend, but you have to pay it back, and the interest is enormous. It destroys far more than the pleasure it started with.
• Another thing: neither Jesus's parable nor Psalm 1 is talking about the happiness of a moment. They're talking about the blessing of an entire life lived Christ's way. And that kind of argument can only be judged at the end of a life. Maybe, for a moment, there's some pleasure. But at the end, there's ruin.
• The fool, meanwhile, built his house on sandy ground, or planted his tree in the sand. We've all seen floods. We know what happens when the waters rise and the foundation is bad.
• The preacher uses the image of the Eiffel Tower. We now know it was built on marshland. The Champ de Mars, before, was waterlogged ground. What did it take? Draining the water, drying out the soil, digging very deep before laying the structure. When you look at the base of the tower today, there's no more soil there: it's all brick and stone. It has lived through several world wars and shows no sign of falling. "Jesus wants you to be Eiffel Towers in your own Paris; the kind that last."
• A word of caution: Jesus isn't talking about someone who has never heard, but about someone who has heard, who has probably understood, but who neglects the Word or rejects it. We hope that at the first rains, this person wakes up. But instead they build their life on sand. They're proud of that sand, they place their hope in that sand. That's the whole folly of it, and why Jesus ultimately speaks of ruin and condemnation.

4. Why the Word of Christ carries such authority

• Why do the words of Christ matter so much? The preacher points you back to the source. She recalls that for Moses, God gave instructions; especially when he provided manna from heaven.
• Deuteronomy 8:3 answers: "He humbled you, and allowed you to be hungry, and fed you with manna, which you didn't know, neither did your fathers know, that he might make you know that man does not live by bread only, but by everything that proceeds out of the mouth of Yahweh does man live."
• For those who disobeyed; those who said, "fine, okay, you're giving us manna, you'll give us more tomorrow, so I'll do whatever I want with this provision", God held them accountable for what they knew. They heard the words and ignored them. They suffered the consequences. That's normal in our world too.
• But why does God go through the word at all? If he wants us to obey, why doesn't he just plant it in our hearts so we react naturally? The preacher quotes Dallas Willard: "God can make himself present to the human mind in whatever way he chooses, but for good reasons, deeply rooted in the nature of the person and of personal relationships, his preferred way of communicating is to speak."
• God created us as social beings. We're normally born into a family; even a small one, even with just one parent, no one is born alone. The way God designed it, humans live in community. He created us to communicate and live together.
• What sets us apart from animals is complex language: we can communicate without having to move. The preacher is doing it right now; she's using words, you're hearing them, and something happens in your mind. All of this is God's creation. And it goes all the way back to Genesis. When God says, "Let there be light," "Let us make man in our image," you already glimpse the relationship within the Godhead. We're created in his image, and we need to communicate, to use words.
• That's why God communicates with us through words. And if God speaks to us in words, he is the source, so those words carry supreme value. Even more so when it's the one who is the Word of life, the Word made flesh (John 1:14), greater than Moses.

5. God's compassion toward your weakness

• God, in his compassion, took your weakness into account. He understood that sometimes you want to build your house on the rock, but sometimes you doubt, sometimes you're tempted, and sometimes you're simply rebellious.
• He understood this weakness, and what did he do? He sent his Son. During his life on earth, Jesus showed what it looks like to live as the wise man who built his house on the rock. John 5:19: "The Son can do nothing of himself, but what he sees the Father doing." He showed us what that looks like.
• And because you still can't manage it on your own, what has he given you? The Holy Spirit, who changes you, who gives you the desire to change, and who gives you what you need to actually do it. "It's wonderful, isn't it?"
• That's why the foolish man is, in the end, without excuse, and why his ruin is so great.

6. Two endings, one future

• To close, the preacher sums it up. She's shared the illustration of the man who built his house on the rock. It's a metaphor. "The Lord isn't calling us to move into a building; he's calling us to build our lives."
• In one case, you hear what he says and you let it change you. What happens? You go through trials, disappointments, failures, tragedies. But you're not alone, you hold firm, you come through as more than a conqueror, and you're welcomed into eternity.
• In the other, you hear what he says, you forget, you neglect it. What happens? You face the same trials, the same disappointments, the same failures, the same tragedies. What's the final outcome? Eternal ruin.
• Who can say such a thing? Who has that kind of authority? "Only the one who knows the beginning and the end; only the Judge himself." And here's the wonder of it: that same person is also the one who gave his own life to secure your place in paradise.

Key Takeaways

• Jesus warns you: he doesn't shy away from the facts, and he puts a clear choice in front of you. Hear and do it, or hear and neglect it.
• The storm will come against both houses. The difference isn't in the weather; it's in the foundation. Your foundation is what you do with the words of Christ.
• The trials that hit you; slander, anxiety, the consequences of your own sins, false ideas; are real. The Word of Christ, meditated on and put into practice, gives you the power and the perspective to hold on to the very end.
• Sin isn't "more fun", it's a very bad loan, with enormous interest. You don't judge a life by the pleasure of a moment, but by how it ends.
• God hasn't left you alone: he sent his Son, who lived the life of the wise man, and then his Holy Spirit, who changes you from the inside. The fool, in the end, is without excuse.

Personal Application

• What specific word of Christ, heard recently, are you hearing without putting it into practice? What's holding you back from a concrete step this week?
• The last time slander or criticism hit you, what did you do? Did you go looking for the Word (Matthew 5:21-22), or did you grab your phone to strike back?
• Faced with a worry that won't let go of you, do you dare to pray with "Consider the birds of the sky" (Matthew 6:26), or does that reflex feel, just like it does to the world, completely absurd to you?
• Where in your life are you tempted to say, "God will provide tomorrow, so I'll do whatever I want today"? Are you willing to admit that, in that moment, you're building on sand?
• What foundation are you really building your life on these past few months; your success, your pleasures, your relationships, your comfort; or the words of Christ put into practice?

FAQ

Does the parable of the two houses mean Christians are spared from trials?

No, and that's exactly the point of the text. Both houses face the same rain, the same flood, the same wind. Jesus doesn't promise you a life without storms: he promises that if you build on his words and put them into practice, your house will stand. The difference isn't in the weather; it's in the foundation.

What does it actually mean to "put into practice" the words of Jesus?

The preacher gives two concrete examples. When you're slandered, instead of feeding your anger and striking back on your phone, you respond out of Matthew 5:21-22. When you're eaten up by worry, you go to Matthew 6:26-28 and look at the birds, the flowers, because the Creator is your Father. Putting it into practice isn't about perfecting a theory; it's letting the Word straighten out your reflexes.

How can the fool be "without excuse" if he went through the same storms?

Because he heard. Jesus isn't talking about someone who never heard, but about someone who heard and neglected it. God sent him his Son, who lived out the life of the wise man right in front of him. He offered him the Holy Spirit to change his heart. Neglecting all of that means building on sand with your eyes wide open: the final ruin isn't an injustice; it's the result of a choice.
