Shaken & Stirred – Sermon on Luke 21:25-36 for the Second Sunday of Advent

Luke 21:25–36

25 “And there will be signs in sun and moon and stars, and on the earth distress of nations in perplexity because of the roaring of the sea and the waves, 26 people fainting with fear and with foreboding of what is coming on the world. For the powers of the heavens will be shaken. 27 And then they will see the Son of Man coming in a cloud with power and great glory. 28 Now when these things begin to take place, straighten up and raise your heads, because your redemption is drawing near.”

29 And he told them a parable: “Look at the fig tree, and all the trees. 30 As soon as they come out in leaf, you see for yourselves and know that the summer is already near. 31 So also, when you see these things taking place, you know that the kingdom of God is near. 32 Truly, I say to you, this generation will not pass away until all has taken place. 33 Heaven and earth will pass away, but my words will not pass away.

34 “But watch yourselves lest your hearts be weighed down with dissipation and drunkenness and cares of this life, and that day come upon you suddenly like a trap. 35 For it will come upon all who dwell on the face of the whole earth. 36 But stay awake at all times, praying that you may have strength to escape all these things that are going to take place, and to stand before the Son of Man.”

In the name of Jesus. Amen.

We’ll get to this text, I promise. But first, I want to make a quick comment on our liturgy. Right away, the term or word “liturgy” might seem dull or dry. But the word ‘liturgy’ is a biblical word that simply means ‘public service.’ It seems less common now, but people used to talk about a church either being ‘liturgical’ or ‘contemporary.’ But that isn’t a helpful distinction because every church has a liturgy. In some churches, that order looks like singing for a long time, hearing a sermon, singing again, and leaving the building. You know what the service looks like here. And in other churches you may have attended, it looks different. When Christians gather together in church, they do things in a particular order, and that order is the liturgy.

I’m not sure when, but sometime in the not-too-distant future I’m going to take the time during a Sunday morning service to explain the different parts of our service and why we do what we do when we do it. But that’s for another time.

‌Today, I want to highlight one of the parts of our liturgy which is the Collect. It’s that short prayer that is offered right after the Confession and Absolution and before the Scripture readings. The Collect changes every week, because it takes the different Scripture readings we hear during the service and collects (hence the name) them into a prayer that we offer to God. What the Collect does is it sets the theme for what we will hear from God’s Word each week. People have traced the origins of these prayers far back through Church history. They have been used by Christians since the 400-500’s.

‌I printed the main part of today’s Collect there for you in the Scripture insert, and I want to draw your attention to it again right now. “Stir up our hearts, O Lord, to make ready the way of Your only-begotten Son, that by His coming we may be enabled to serve You with pure minds.” It’s a good prayer because we need to have our hearts stirred up by God, and Jesus certainly does that in this Gospel reading. Jesus says that the day is coming when, “The powers of the heavens will be shaken” (Lk. 21:26).

‌Shaking the heavens is no problem for God. God created all the celestial bodies on the fourth day of creation by simply speaking (Gen. 1:14-19). All the planets, solar systems, stars, and galaxies didn’t get where they are by accident. God did it with precision. Earth is about 91.6 million miles from the sun. If it were a tiny fraction closer to the sun, the whole planet would fry; a tiny fraction further, and it would freeze. And it isn’t just Earth’s proximity to the sun that sustains life. It is tilted in just the right way as well. Also, God created the other planets of our solar system in the right sizes and set them at the right distances to keep our orbit just right and protect us from asteroids. Our moon is just the right size and distance to sustain life on the planet by causing the high and low tides. And I wouldn’t be at all surprised if the Milky Way galaxy is the perfect distance from other galaxies and black holes too.

‌You probably know the rule In carpentry, “Measure twice; cut once.” I’m not sure how to state a similar rule for creating the universe. Maybe, “Measure twice; carefully place all the powers of the heavens in their positions once.”

‌Well, Jesus tells us that all of it is going to be shaken. Normally, when things are shaken, it’s a violent and chaotic thing. You shake something and stuff goes all over the place and ends up in random positions when the shaking stops. But the same precision that God used in creating the heavens will also be used when God shakes them. Yes, everything is going to be shaken, but that doesn’t mean God isn’t in control of what’s happening.

‌Shaking the heavens is no problem for God. The bigger problem is stirring our stubborn hearts. That’s why Jesus tells us to “stay awake at all times, praying that you may have strength to escape all these things that are going to take place, and to stand before the Son of Man” (Lk. 21:36). In other words, don’t get in a tizzy when the powers of the heavens are shaken. Instead, pray that as the universe shakes that God would strengthen you to stand before Him when He returns.

‌This past Thursday, a news alert came on my phone that there had been an earthquake off the coast of central California and a tsunami warning had been issued. I said a quick prayer for the people and cities. (I’d encourage you, when you get an alert like that or when you hear sirens, the first thing to do is pray. At least send up a, “Lord, have mercy.”) About half an hour after I saw that alert, I took a break to check Twitter – I still can’t call it ‘X’ – to see if there was a tsunami since I know people who live in that area. I found a bunch of posts from people who lived in that area, and most of them were saying that they were more startled by the alert from their phone than they were worried about being swept away. I was fairly shocked. Even though a tsunami could still have been coming, people were complaining that the buzzing and noise from their phone was too loud.

‌Now, I know those emergency alerts are very shocking, but they’re supposed so they grab our immediate attention. But I found it remarkably interesting that people were scared more by their phones than they were about the possibility of their cars, houses, workplaces, and city being completely swept away in an instant.

‌But then, I realized that all those comments of misdirected fear is what I and, probably, most of us do. We get riled up about all sorts of things, but the things that get us riled up aren’t what is most important. Especially this time of year, we focus more on what gifts to buy, how much money we are spending, rushing around for all the parties and get-togethers, and the final exams or papers. But are we preparing to stand before Christ, the Son of Man? Our concern for temporary tings often leads to complacency about eternal things. Remember what Jesus says, “Heaven and earth will pass away, but My Words will not pass away” (Lk. 21:33).

When you listen to the world, what do you hear them talking about? You hear about wars and rumors of wars. They talk about the atmosphere and “catastrophic global climate change.” And they’re definitely perplexed about all of it. Many of the signs Jesus speaks about in this text are the constant chatter of our day and age.

‌Dear saints, God would have you speak differently than the world speaks. You can see the different calamities happening in our world and use them as an opportunity to share the joy and hope you have of the Savior’s return. Yes, it is clear that creation isn’t going to last forever. This world will not endure because of the sin we have brought into it. But you know that Christ is risen. You know that His death and resurrection was to save the world. You know that your Redeemer promises to make all things new, and again, His words will not pass away. What He has promised will surely happen.

‌Jesus, your Savior, is coming again for your redemption. That puts a new perspective on all the evil and chaos of this world. You have Christ’s promise that the things you struggle with and have to endure in this world will cease and be replaced with the joy of living in God’s eternal kingdom.

‌Even as the powers of the heavens are shaken, we pray that God would stir up our hearts to be ready for Jesus’ coming. The cares of this life are certainly real, but they are nothing compared to the redemption that is coming and drawing near.

Dear saints, in the midst of the evil of this broken world, straighten up. Raise your heads. Your redemption is coming, and it is drawing near. Amen.

The peace of God, which surpasses all understanding, will guard your hearts and minds in Christ Jesus. Amen.
