This message introduces our new series for 2026-2027, studying the Old Testament book of Jeremiah. To lay the foundation

Looking at Jesus's announcement that he will build his church, the sermon argues that the church's role in society is prophetic rather than kingly or priestly: revealing truth the world cannot know on its own, holding out hope that Satan will not win, and bringing heaven close to earth. It introduces Jeremiah as the book that trains a church for exactly that.

The passages

Now when Jesus came into the parts of Caesarea Philippi, he asked his disciples, saying, “Who do men say that I, the Son of Man, am?” They said, “Some say John the Baptizer, some, Elijah, and others, Jeremiah or one of the prophets.” He said to them, “But who do you say that I am?” Simon Peter answered, “You are the Christ, the Son of the living God.” Jesus answered him, “Blessed are you, Simon Bar Jonah, for flesh and blood has not revealed this to you, but my Father who is in heaven. I also tell you that you are Peter, and on this rock I will build my assembly, and the gates of Hades will not prevail against it. I will give to you the keys of the Kingdom of Heaven, and whatever you bind on earth will have been bound in heaven; and whatever you release on earth will have been released in heaven.” Then he commanded the disciples that they should tell no one that he was Jesus the Christ.

Matthew 16:13–20

Jesus therefore answered them, “Most certainly, I tell you, the Son can do nothing of himself, but what he sees the Father doing. For whatever things he does, these the Son also does likewise.

John 5:19

“Behold, the days come,” says Yahweh, “that I will make a new covenant with the house of Israel, and with the house of Judah, not according to the covenant that I made with their fathers in the day that I took them by the hand to bring them out of the land of Egypt, which covenant of mine they broke, although I was a husband to them,” says Yahweh. “But this is the covenant that I will make with the house of Israel after those days,” says Yahweh: “I will put my law in their inward parts, and I will write it in their heart. I will be their God, and they shall be my people. They will no longer each teach his neighbor, and every man teach his brother, saying, ‘Know Yahweh;’ for they will all know me, from their least to their greatest,” says Yahweh, “for I will forgive their iniquity, and I will remember their sin no more.”

Jeremiah 31:31–34

Go deeper

How do I know what's true when the world around me keeps calling wrong right?

Peter got his answer about Jesus without a classroom, and Jesus said his Father gave it to him. Jeremiah stood in a city that was sure it was fine while it was drifting, and he kept saying what God actually said.

Now when Jesus came into the parts of Caesarea Philippi, he asked his disciples, saying, “Who do men say that I, the Son of Man, am?” They said, “Some say John the Baptizer, some, Elijah, and others, Jeremiah or one of the prophets.” He said to them, “But who do you say that I am?” Simon Peter answered, “You are the Christ, the Son of the living God.” Jesus answered him, “Blessed are you, Simon Bar Jonah, for flesh and blood has not revealed this to you, but my Father who is in heaven.

Matthew 16:13–17

Now Yahweh’s word came to me, saying, “Before I formed you in the womb, I knew you. Before you were born, I sanctified you. I have appointed you a prophet to the nations.” Then I said, “Ah, Lord Yahweh! Behold, I don’t know how to speak; for I am a child.” But Yahweh said to me, “Don’t say, ‘I am a child;’ for you must go to whomever I send you, and you must say whatever I command you. Don’t be afraid because of them, for I am with you to rescue you,” says Yahweh. Then Yahweh stretched out his hand and touched my mouth. Then Yahweh said to me, “Behold, I have put my words in your mouth. Behold, I have today set you over the nations and over the kingdoms, to uproot and to tear down, to destroy and to overthrow, to build and to plant.”

Jeremiah 1:4–10

Jesus therefore said to those Jews who had believed him, “If you remain in my word, then you are truly my disciples. You will know the truth, and the truth will make you free.”

John 8:31–32

Every Scripture is God-breathed and profitable for teaching, for reproof, for correction, and for instruction in righteousness, that each person who belongs to God may be complete, thoroughly equipped for every good work.

2 Timothy 3:16–17

Is there any real hope left when it feels like evil is winning everywhere?

Jesus said the gates of Hades would not overcome the church he builds. Jeremiah lived through the darkest stretch of Israel's story and still announced a new covenant in the middle of it.

I also tell you that you are Peter, and on this rock I will build my assembly, and the gates of Hades will not prevail against it.

Matthew 16:18

“Behold, the days come,” says Yahweh, “that I will make a new covenant with the house of Israel, and with the house of Judah, not according to the covenant that I made with their fathers in the day that I took them by the hand to bring them out of the land of Egypt, which covenant of mine they broke, although I was a husband to them,” says Yahweh. “But this is the covenant that I will make with the house of Israel after those days,” says Yahweh: “I will put my law in their inward parts, and I will write it in their heart. I will be their God, and they shall be my people. They will no longer each teach his neighbor, and every man teach his brother, saying, ‘Know Yahweh;’ for they will all know me, from their least to their greatest,” says Yahweh, “for I will forgive their iniquity, and I will remember their sin no more.”

Jeremiah 31:31–34

We know that we are of God, and the whole world lies in the power of the evil one.

1 John 5:19

No, in all these things we are more than conquerors through him who loved us. For I am persuaded that neither death, nor life, nor angels, nor principalities, nor things present, nor things to come, nor powers, nor height, nor depth, nor any other created thing will be able to separate us from God’s love which is in Christ Jesus our Lord.

Romans 8:37–39

What does it actually look like to bring heaven into my ordinary week?

Jesus gave Peter keys, and the sermon describes the prophet as someone for whom the line between heaven and earth is thin. Elisha's servant saw chariots of fire, Stephen saw Jesus standing, and Isaiah saw the Lord high and lifted up.

I will give to you the keys of the Kingdom of Heaven, and whatever you bind on earth will have been bound in heaven; and whatever you release on earth will have been released in heaven.”

Matthew 16:19

When the servant of the man of God had risen early and gone out, behold, an army with horses and chariots was around the city. His servant said to him, “Alas, my master! What shall we do?” He answered, “Don’t be afraid, for those who are with us are more than those who are with them.” Elisha prayed, and said, “Yahweh, please open his eyes, that he may see.” Yahweh opened the young man’s eyes, and he saw; and behold, the mountain was full of horses and chariots of fire around Elisha.

2 Kings 6:15–17

But he, being full of the Holy Spirit, looked up steadfastly into heaven and saw the glory of God, and Jesus standing on the right hand of God, and said, “Behold, I see the heavens opened and the Son of Man standing at the right hand of God!”

Acts 7:55–56

In the year that King Uzziah died, I saw the Lord sitting on a throne, high and lifted up; and his train filled the temple. Above him stood the seraphim. Each one had six wings. With two he covered his face. With two he covered his feet. With two he flew. One called to another, and said, “Holy, holy, holy, is Yahweh of Armies! The whole earth is full of his glory!” The foundations of the thresholds shook at the voice of him who called, and the house was filled with smoke. Then I said, “Woe is me! For I am undone, because I am a man of unclean lips and I live among a people of unclean lips, for my eyes have seen the King, Yahweh of Armies!”

Isaiah 6:1–5

Why does standing in the middle mean taking abuse from both sides?

The sermon says the prophet is not the king forcing everyone to comply and not the priest withdrawn into a private circle. It's the one who stands in between and gets hit from both directions, the way Jeremiah did and the way Jesus did.

Yahweh, you have persuaded me, and I was persuaded. You are stronger than I, and have prevailed. I have become a laughingstock all day. Everyone mocks me. For as often as I speak, I cry out; I cry, “Violence and destruction!” because Yahweh’s word has been made a reproach to me, and a derision, all day. If I say that I will not make mention of him, or speak any more in his name, then there is in my heart as it were a burning fire shut up in my bones. I am weary with holding it in. I can’t. For I have heard the defaming of many: “Terror on every side! Denounce, and we will denounce him!” say all my familiar friends, those who watch for my fall. “Perhaps he will be persuaded, and we will prevail against him, and we will take our revenge on him.”

Jeremiah 20:7–10

“Blessed are you when people reproach you, persecute you, and say all kinds of evil against you falsely, for my sake. Rejoice, and be exceedingly glad, for great is your reward in heaven. For that is how they persecuted the prophets who were before you.

Matthew 5:11–12

Are they servants of Christ? (I speak as one beside himself.) I am more so: in labors more abundantly, in prisons more abundantly, in stripes above measure, and in deaths often. Five times I received forty stripes minus one from the Jews. Three times I was beaten with rods. Once I was stoned. Three times I suffered shipwreck. I have been a night and a day in the deep. I have been in travels often, perils of rivers, perils of robbers, perils from my countrymen, perils from the Gentiles, perils in the city, perils in the wilderness, perils in the sea, perils among false brothers; in labor and travail, in watchings often, in hunger and thirst, in fastings often, and in cold and nakedness. Besides those things that are outside, there is that which presses on me daily: anxiety for all the assemblies.

2 Corinthians 11:23–28

If you are insulted for the name of Christ, you are blessed, because the Spirit of glory and of God rests on you. On their part he is blasphemed, but on your part he is glorified. But let none of you suffer as a murderer, or a thief, or an evil doer, or a meddler in other men’s matters. But if one of you suffers for being a Christian, let him not be ashamed; but let him glorify God in this matter.

1 Peter 4:14–16
