Day 2974– “What A Difference Jesus Makes” – Luke 13:18-35
Putnam Church Message – 10/11/2026
The Good News According to Luke: “Straight Talk for Saints and Sinners”
Last week, our message was “What a Difference Jesus Makes!” and we learned that when Jesus steps into the story… everything changes.
>Today, we continue with our forty-second message from Luke’s narrative of the Good News of Jesus Christ. Today’s message is “Straight Talk for Saints and Sinners.” Our core passage today is Luke 13:18-35, starting on page 1620 of your pew Bibles.
The Parables of the Mustard Seed and the Yeast
18 Then Jesus asked, “What is the kingdom of God like? What shall I compare it to? 19 It is like a mustard seed, which a man took and planted in his garden. It grew and became a tree, and the birds perched in its branches.”
20 Again he asked, “What shall I compare the kingdom of God to? 21 It is like yeast that a woman took and mixed into about sixty pounds of flour until it worked all through the dough.”
The Narrow Door
22 Then Jesus went through the towns and villages, teaching as he made his way to Jerusalem. 23 Someone asked him, “Lord, are only a few people going to be saved?”
He said to them, 24 “Make every effort to enter through the narrow door, because many, I tell you, will try to enter and will not be able to. 25 Once the owner of the house gets up and closes the door, you will stand outside knocking and pleading, ‘Sir, open the door for us.’
“But he will answer, ‘I don’t know you or where you come from.’
26 “Then you will say, ‘We ate and drank with you, and you taught in our streets.’
27 “But he will reply, ‘I don’t know you or where you come from. Away from me, all you evildoers!’
28 “There will be weeping there, and gnashing of teeth, when you see Abraham, Isaac and Jacob and all the prophets in the kingdom of God, but you yourselves thrown out. 29 People will come from east and west and north and south, and will take their places at the feast in the kingdom of God. 30 Indeed there are those who are last who will be first, and first who will be last.”
Jesus’ Sorrow for Jerusalem
31 At that time some Pharisees came to Jesus and said to him, “Leave this place and go somewhere else. Herod wants to kill you.”
32 He replied, “Go tell that fox, ‘I will keep on driving out demons and healing people today and tomorrow, and on the third day I will reach my goal.’ 33 In any case, I must press on today and tomorrow and the next day—for surely no prophet can die outside Jerusalem!
34 “Jerusalem, Jerusalem, you who kill the prophets and stone those sent to you, how often I have longed to gather your children together, as a hen gathers her chicks under her wings, and you were not willing. 35 Look, your house is left to you desolate. I tell you, you will not see me again until you say, ‘Blessed is he who comes in the name of the Lord.’[b]”
Opening Prayer
Father, we come before You asking for truth without disguise and grace without compromise.
Lord Jesus, teach us to hear Your words as they are—clear, loving, urgent, and true. Give us humility when Your truth corrects us, courage when it challenges us, patience when Your Kingdom seems slow, and faith when the road ahead looks hard.
Holy Spirit, open our hearts so that saints and sinners alike may hear what the King is saying today.
In Jesus’ name, amen.
Introduction: The Small Beginning Nobody Notices
A farmer once planted a tiny seed in a corner of his property. For days, nothing seemed to happen. He watered the soil. Still nothing. A week passed. Nothing obvious.
Someone looking from the road might have said, “That seed is doing nothing.”
But beneath the surface, roots were forming. Life was beginning. What looked inactive was actually alive. Then one morning, a small green shoot broke through the soil.
That is a good picture of the Kingdom of God. / Years later, the thing that began as something almost invisible had become impossible to ignore.
Last week, in “What A Difference Jesus Makes!”, we saw Jesus call people to repentance, warn them not to judge tragedy simplistically, and then set a bent-over daughter of Abraham free on the Sabbath.
The Kingdom was not just being discussed. / It was arriving. / A woman stood upright. / A captive was released. / Religious hypocrisy was exposed.
And today Jesus keeps speaking plainly.
- No slogans.
- No public-relations spin.
- No attempt to make the future sound easier than it would be.
He tells His followers three uncomfortable truths:
- The Kingdom may start small, but it will prevail.
- The invitation is open, but the door will not remain open forever.
- And the Messiah’s path to glory runs straight through rejection, suffering, and death.
That is why today’s title is: “Straight Talk for Saints and Sinners”
Because Jesus tells the truth to everyone.
- To the curious.
- To the committed.
- To the religious.
- To the rebellious.
- To the saint.
- To the sinner.
- And His truth is always gracious—but never soft.
Today, let’s explore four truths to help us understand the coming of God’s kingdom more fully.
Truth 1: The Kingdom May Begin Small, But It Will Not Stay Small
Luke 13:18–21 Jesus asks: “What is the Kingdom of God like?”
Then He answers with two ordinary pictures. / A mustard seed. / And yeast in dough… Nothing flashy. / Nothing political. / Nothing militaristic. / That itself is surprising.
The Mustard Seed
In Jesus’ world, mustard seed was commonly used to picture something very small. / Tiny. / Easy to miss. / Easy to dismiss.
Yet under the right conditions, the plant could grow large enough for birds to rest in its branches.
- Jesus is saying: Do not judge the Kingdom by its beginning.
- That would be like looking at an acorn and saying: “That could never become an oak.”
- Or looking at Bethlehem and saying: “That could never produce a King.”
- Or looking at twelve ordinary disciples and saying: “They could never change the world.” / But they did.
Ancient Israelite Background
The image of a large tree sheltering birds appears in Old Testament passages such as Ezekiel 17 and Ezekiel 31.
In those passages, great trees can symbolize kingdoms and empires providing shelter to nations.
Jesus takes that image and applies it to God’s Kingdom.
The Kingdom begins with a carpenter from Nazareth. / A few fishermen. / Some women. / A tax collector. / Ordinary people. / No army. / No palace. / No treasury. / No earthly throne.
And yet the branches spread. / Jerusalem. / Judea. / Samaria. / The ends of the earth.
Divine Council Perspective
This fits the larger biblical story we have been tracing. After Babel, the nations were scattered and, in the language of Deuteronomy 32, placed under members of the heavenly divine council. / But God’s plan was always to reclaim them. / He called Abraham and promised that through his family all nations would be blessed.
Now Jesus, the Messiah and rightful King, announces the Kingdom. / The seed has been planted. / The nations will come. / Revelation ends with people from every tribe, language, people, and nation gathered before the Lamb. / What began small will fill the world.
The Yeast
Then Jesus gives a second picture. A woman takes a small amount of yeast and mixes it into a large amount of flour. The yeast disappears. You cannot point to it and say: “There it is.” / But it works. / Quietly. / Internally. / Inevitably. / Eventually, the whole batch is changed.
That is what the Kingdom does. / It changes people from the inside out.
We saw that two weeks ago in “Clean From The Inside Out.”
The Kingdom does not merely polish behavior. / It transforms the heart.
Object Lesson: Yeast Packet and Loaf of Bread
Hold up a yeast packet in one hand and a loaf of bread in the other.
Ask: “Which one looks more impressive?” / Obviously, the loaf.
But the lesson is this: The biggest things in God’s Kingdom often begin in ways that look unimpressive.
A quiet prayer. / A small act of obedience. / A conversation about Jesus. / A child learning Scripture. / A generous gift no one notices. / A person forgiving an enemy. / Never despise small beginnings.
Modern Illustration
We live in a culture obsessed with instant results. / Views. / Followers. / Growth charts. / Attendance. / Quarterly reports.
We assume big means important.
Jesus says: Not necessarily. / God may be doing His deepest work where nobody is applauding.
The first lesson is: Do not mistake small beginnings for small purposes. The Kingdom of God works quietly, but it works inevitably.
Truth 2: The Door Is Open, But It Is Narrow—and It Will Not Stay Open Forever
Luke 13:22–30 As Jesus continues toward Jerusalem, someone asks: “Lord, will only a few be saved?”
That is an interesting question. And Jesus does what He often does. He refuses to satisfy curiosity without confronting the heart.
The person asks: “How many?”
Jesus answers: “What about you?”
He says: “Work hard to enter the narrow door.” / “Strive”
The Greek word carries the idea of an athlete exerting himself or a competitor straining toward the goal. It gives us the word agonize.
Jesus is not teaching salvation by human effort.
Elsewhere, Scripture is clear: salvation comes by grace through faith.
Jesus is confronting complacency.
He is saying: Do not treat the Kingdom casually. / Do not assume proximity is enough. / Do not assume religious familiarity guarantees entrance.
The Narrow Door
The image is likely a smaller entrance set within a larger gate. / The point is not that God enjoys making salvation difficult.
The point is that God has appointed an entrance.
Jesus later says in John 10: “I am the gate.” And in John 14: “I am the way.” / The door is open. / But the door is Christ.
Then Jesus describes people knocking after the door is shut.
They say: “We ate and drank with You.” “You taught in our streets.”
In modern language: “We went to church.” “We knew Christian songs.” “We had a Bible.” “We heard sermons.” “We lived around religious people.”
Jesus says none of that substitutes for knowing Him. That is a grave warning for religious insiders.
Abraham, Isaac, Jacob—and the Nations
Then Jesus says people will come from east and west, north, and south, and sit at the feast in the Kingdom of God. / There it is again. / The nations. / The Abrahamic promise. / The Divine Council storyline. / The scattered peoples are being gathered under the true King. /
And some who assumed they were “in” because of heritage may discover that outsiders have entered by faith. /
That would have shocked many in Jesus’ audience.
Old Testament Connection
Isaiah envisioned nations streaming to God’s Mountain.
Psalm 22 says all the families of the nations will worship before the Lord.
Isaiah 49 says the Servant will be a light to the nations.
Jesus is saying: That day is coming. / The table will be full. / But ancestry is not your dinner ticket. / Faith is.
Object Lesson: An Open Door
If possible, point toward a door.
Say: “As long as that door is open, people can enter.”
Then close it. “When the door closes and locks, opportunity ends.”
That is the urgency of Jesus’ teaching. / Not panic. | Urgency. / There is a difference.
Modern Illustration
We postpone important things all the time. / “I’ll make that phone call later.” / “I’ll deal with that relationship later.” / “I’ll get serious about God later.”
But later is not promised.
The second lesson is: Do not ask how many will be saved while postponing your own response to Christ. The door is open now. Enter while there is time.
