Event 34 — Public Preaching Begins in Galilee

If you could boil Jesus’ whole message down to a single sentence, the Gospels already did it for you. This is that sentence — His opening headline, the announcement everything else unpacks.

Matthew 4:17 Mark 1:14–15; Luke 4:14–15 Event 34 of the harmony The Life of Jesus
The big picture

“The time is fulfilled, and the kingdom of God is at hand”

With John now in prison, Jesus steps fully into public ministry, and the Gospels hand us His headline — the one-sentence summary of everything He came to proclaim: “The time is fulfilled, and the kingdom of God is at hand; repent and believe in the gospel.” Every phrase carries weight. The long-promised, decisive moment has finally arrived. God’s reign is breaking into the world in the person of the King who is speaking. And the way in has two hands: turn from sin, and trust the good news. Jesus takes up John’s call to repent and adds the note John could only point toward — “believe the gospel,” for the King Himself has now come.

Matthew’s summary: 17From that time Jesus began to preach and say, “Repent, for the kingdom of heaven is at hand.”

Mark 1:14–15; Matthew 4:17; Luke 4:14–15 (NASB95)
📖 Read each account

Read Mark 1:14–15, Matthew 4:17, and Luke 4:14–15. “Kingdom of heaven” (Matthew) and “kingdom of God” (Mark, Luke) mean the same thing — Matthew, writing for Jewish readers, reverently says “heaven” in place of the divine name.

Word secrets

What the original words mean

Five words that unpack one sentence.

Mark 1:15 · “the time is fulfilled”
πεπλήρωται ὁ καιρός
peplērōtai ho kairos
Literal: the appointed time has been filled up

Not ordinary clock-time (chronos) but kairos — the decisive, appointed moment. The long centuries of promise have been “filled up” to the brim; the hour the prophets pointed to has struck. Paul says it the same way: “when the fullness of the time came, God sent forth His Son” (Galatians 4:4).

↑ Back to the passage
Mark 1:15 · “the kingdom of God”
ἡ βασιλεία τοῦ θεοῦ
hē basileia tou theou
Literal: the reign / kingship of God

Less a place than a reality: God’s active rule breaking into the world. Israel had waited for the day God would reign as King and put everything right (Daniel 2:44; 7:14). Jesus announces that day is arriving — in Himself. Where the King is, the kingdom has come near.

↑ Back to the passage
Mark 1:15 · “is at hand”
ἤγγικεν
ēngiken
Literal: has come near / drawn close

The kingdom is no longer far off on the horizon; it has “drawn near” — near enough to step into, near enough to demand a response now. This is the “already” of the kingdom: present in the King, even as its full arrival still lies ahead.

↑ Back to the passage
Mark 1:15 · “repent”
μετανοεῖτε
metanoeite
Literal: change your mind, turn around

The same word John thundered in the wilderness — a U-turn of mind and life. A new King is here, so the only fitting response is to turn: away from sin and self-rule, toward Him. Repentance is not the price of entering the kingdom but the doorway shaped to fit it.

↑ Back to the passage
Mark 1:14–15 · “the gospel”
τὸ εὐαγγέλιον
to euangelion
Literal: good news

The word announced an emperor’s victory or birthday — royal good news (the same word the angels used over Bethlehem). Jesus calls His message the “gospel of God,” and the command is not only to repent but to believe it. This is the joy John could only point toward: the King has actually come, and the good news is to be trusted.

The world of the passage

Four phrases, one announcement

“The time is fulfilled” — the long-promised, appointed moment has come
“The kingdom of God is at hand” — God’s reign is breaking in, in the King Himself
“Repent” — turn from sin and self-rule toward the King
“Believe in the gospel” — trust the good news that the King has come
🏺 What “the kingdom of God” meant to Jesus’ hearers

For a first-century Jew, “the kingdom of God” was a charged, hopeful phrase. Under Roman occupation, Israel longed for the day God would step in as King — ending exile, defeating enemies, and ruling the world from Zion, as Daniel had seen: “the God of heaven will set up a kingdom which will never be destroyed” (Daniel 2:44). When Jesus says that kingdom is “at hand,” the crowds’ hearts would have leapt — though His version of the kingdom would surprise them. It would come not by an army but by a cross; it would grow like a hidden seed; and its King would reign by serving and dying. The headline is thrilling, but it would take the rest of the Gospels to show what kind of kingdom He meant.

📜 “In the power of the Spirit” — the anointed mission

Luke notes that Jesus returned to Galilee “in the power of the Spirit” (4:14). The Spirit who descended at His baptism and led Him through the wilderness now drives His public ministry. The very next event — the synagogue at Nazareth — will make this explicit, when Jesus reads Isaiah’s words, “The Spirit of the Lord is upon Me, because He anointed Me to preach the gospel” (Luke 4:18; Isaiah 61:1). The kingdom Jesus announces is launched in the power of God’s Spirit, not human strength — and that same Spirit is what He will pour out on His people.

Discussion questions

  • Jesus sums up His whole message in one sentence. To a people under Rome longing for God to reign, what would “the kingdom of God is at hand” have stirred?
  • “The time is fulfilled” uses a word for the decisive, appointed moment. How does it change things to see Jesus’ arrival as the climax the whole Old Testament was building toward?
  • The response is two-handed: repent and believe. Why do both belong together, and what is lost if we keep only one?
  • Jesus calls His message “the gospel” — royal good news. How is “believe the good news” different in tone from merely “try harder”?
  • Only after all that does the question reach us: the kingdom is “at hand,” near enough to step into now. What would turning toward this King look like in your life this week?
