This message explores the idea that words are incredibly powerful. They don’t just describe things, they do things. Chri
Words are not just descriptions but actions, and God has entrusted his people with speech that can uproot, plant, warn, and heal. The sermon holds up Jeremiah as the model of a prophet whose mouth God touches, and it calls every Christian to speak words of life with love, patience, and courage.
The passages
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.” Moreover Yahweh’s word came to me, saying, “Jeremiah, what do you see?” I said, “I see a branch of an almond tree.” Then Yahweh said to me, “You have seen well; for I watch over my word to perform it.” Yahweh’s word came to me the second time, saying, “What do you see?” I said, “I see a boiling cauldron; and it is tipping away from the north.” Then Yahweh said to me, “Out of the north, evil will break out on all the inhabitants of the land. For behold, I will call all the families of the kingdoms of the north,” says Yahweh. “They will come, and they will each set his throne at the entrance of the gates of Jerusalem, and against all its walls all around, and against all the cities of Judah. I will utter my judgments against them concerning all their wickedness, in that they have forsaken me, and have burned incense to other gods, and worshiped the works of their own hands. “You therefore put your belt on your waist, arise, and say to them all that I command you. Don’t be dismayed at them, lest I dismay you before them. For behold, I have made you today a fortified city, an iron pillar, and bronze walls against the whole land—against the kings of Judah, against its princes, against its priests, and against the people of the land. They will fight against you, but they will not prevail against you; for I am with you”, says Yahweh, “to rescue you.”
Jeremiah 1:9–19
If I speak with the languages of men and of angels, but don’t have love, I have become sounding brass or a clanging cymbal. If I have the gift of prophecy, and know all mysteries and all knowledge, and if I have all faith, so as to remove mountains, but don’t have love, I am nothing. If I give away all my goods to feed the poor, and if I give my body to be burned, but don’t have love, it profits me nothing.
1 Corinthians 13:1–3
God said, “Let there be light,” and there was light.
Genesis 1:3
In the beginning was the Word, and the Word was with God, and the Word was God. The same was in the beginning with God. All things were made through him. Without him, nothing was made that has been made. In him was life, and the life was the light of men. The light shines in the darkness, and the darkness hasn’t overcome it. There came a man sent from God, whose name was John. The same came as a witness, that he might testify about the light, that all might believe through him. He was not the light, but was sent that he might testify about the light. The true light that enlightens everyone was coming into the world. He was in the world, and the world was made through him, and the world didn’t recognize him. He came to his own, and those who were his own didn’t receive him. But as many as received him, to them he gave the right to become God’s children, to those who believe in his name: who were born, not of blood, nor of the will of the flesh, nor of the will of man, but of God. The Word became flesh and lived among us. We saw his glory, such glory as of the only born Son of the Father, full of grace and truth.
John 1:1–14
Go deeper
Why do my words carry more weight than I expect?
A sentence said in a moment can outlive the moment by decades. The tongue is small and the damage or the life it carries is out of all proportion to its size. James watched a whole congregation of people bless God and curse neighbors with the same mouth and could not get over it.
Indeed, we put bits into the horses’ mouths so that they may obey us, and we guide their whole body. Behold, the ships also, though they are so big and are driven by fierce winds, are yet guided by a very small rudder, wherever the pilot desires. So the tongue is also a little member, and boasts great things. See how a small fire can spread to a large forest! And the tongue is a fire. The world of iniquity among our members is the tongue, which defiles the whole body, and sets on fire the course of nature, and is set on fire by Gehenna.
James 3:3–6
Death and life are in the power of the tongue; those who love it will eat its fruit.
Proverbs 18:21
There is one who speaks rashly like the piercing of a sword, but the tongue of the wise heals.
Proverbs 12:18
I tell you that every idle word that men speak, they will give account of it in the day of judgment. For by your words you will be justified, and by your words you will be condemned.”
Matthew 12:36–37
How do I know what God actually wants me to say to someone?
The hardest part is not the courage to speak but the discernment of what to say. Jeremiah had God's word put in his mouth directly, and most of us do not. The sermon's counsel is to ask, to look for the opening God gives rather than the one we create, and to accept that we will sometimes get it wrong.
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.
Jeremiah 1:6–9
Moses said to Yahweh, “O Lord, I am not eloquent, neither before now, nor since you have spoken to your servant; for I am slow of speech, and of a slow tongue.” Yahweh said to him, “Who made man’s mouth? Or who makes one mute, or deaf, or seeing, or blind? Isn’t it I, Yahweh? Now therefore go, and I will be with your mouth, and teach you what you shall speak.”
Exodus 4:10–12
So, then, my beloved brothers, let every man be swift to hear, slow to speak, and slow to anger; for the anger of man doesn’t produce the righteousness of God.
James 1:19–20
Joy comes to a man with the reply of his mouth. How good is a word at the right time!
Proverbs 15:23
What do I do when the person I'm speaking to won't hear it?
Jeremiah was made a bronze wall precisely because the fighting was coming. The sermon treats opposition not as a sign you said the wrong thing but as the expected weather for anyone speaking on God's behalf. The instruction is to keep sowing, not to force a harvest.
“You therefore put your belt on your waist, arise, and say to them all that I command you. Don’t be dismayed at them, lest I dismay you before them. For behold, I have made you today a fortified city, an iron pillar, and bronze walls against the whole land—against the kings of Judah, against its princes, against its priests, and against the people of the land. They will fight against you, but they will not prevail against you; for I am with you”, says Yahweh, “to rescue you.”
Jeremiah 1:17–19
But the house of Israel will not listen to you, for they will not listen to me; for all the house of Israel are obstinate and hard-hearted. Behold, I have made your face hard against their faces, and your forehead hard against their foreheads. I have made your forehead as a diamond, harder than flint. Don’t be afraid of them, neither be dismayed at their looks, though they are a rebellious house.”
Ezekiel 3:7–9
…preach the word; be urgent in season and out of season; reprove, rebuke, and exhort with all patience and teaching. For the time will come when they will not listen to the sound doctrine, but having itching ears, will heap up for themselves teachers after their own lusts, and will turn away their ears from the truth, and turn away to fables. But you be sober in all things, suffer hardship, do the work of an evangelist, and fulfill your ministry.
2 Timothy 4:2–5
Let’s not be weary in doing good, for we will reap in due season if we don’t give up.
Galatians 6:9
How do I speak hard things without speaking them cruelly?
Jeremiah said devastating things to his own people and never stopped weeping for them. The sermon puts love first, not as softness but as the thing that keeps correction from turning into a weapon. Paul wrote a whole letter to a church he had to rebuke and could not say it without saying how much he loved them first.
If I speak with the languages of men and of angels, but don’t have love, I have become sounding brass or a clanging cymbal. If I have the gift of prophecy, and know all mysteries and all knowledge, and if I have all faith, so as to remove mountains, but don’t have love, I am nothing. If I give away all my goods to feed the poor, and if I give my body to be burned, but don’t have love, it profits me nothing.
1 Corinthians 13:1–3
…but speaking truth in love, we may grow up in all things into him who is the head, Christ, from whom all the body, being fitted and knit together through that which every joint supplies, according to the working in measure of each individual part, makes the body increase to the building up of itself in love.
Ephesians 4:15–16
Better is open rebuke than hidden love. The wounds of a friend are faithful, although the kisses of an enemy are profuse.
Proverbs 27:5–6
Let your speech always be with grace, seasoned with salt, that you may know how you ought to answer each one.
Colossians 4:6
Why does Jesus being called the Word change what I say?
The sermon ends by pointing past Genesis to John, where the one who spoke light into being is himself named the Word. If the Word lives in you, then the words you speak are not a performance you put on but a life coming out. Silas and Timothy and every ordinary speaker in Acts were doing the same thing: letting the Word through them reach people.
In the beginning was the Word, and the Word was with God, and the Word was God. The same was in the beginning with God. All things were made through him. Without him, nothing was made that has been made. In him was life, and the life was the light of men. The light shines in the darkness, and the darkness hasn’t overcome it.
John 1:1–5
The Word became flesh and lived among us. We saw his glory, such glory as of the only born Son of the Father, full of grace and truth.
John 1:14
Let the word of Christ dwell in you richly; in all wisdom teaching and admonishing one another with psalms, hymns, and spiritual songs, singing with grace in your heart to the Lord.
Colossians 3:16
For the word of God is living and active, and sharper than any two-edged sword, piercing even to the dividing of soul and spirit, of both joints and marrow, and is able to discern the thoughts and intentions of the heart.
Hebrews 4:12
