Background: Jesus, the Day of the Lord, and the Second Exodus

Opening Hook

Ask your group what they picture when they hear “the Day of the Lord” — most will say something like “the end of the world,” a single cataclysmic future event. Then point out something surprising: when Israel actually returned from exile in Babylon — rebuilt temple, rebuilt walls, priest and governor both in place — nothing about it felt like the fulfillment they’d been promised. By every measure that mattered, they were still in exile. That gap between the promise and the underwhelming “return” is exactly what sets up why Jesus’s arrival was both expected and completely unexpected at the same time.

The Core Teaching

Three source articles feed this session: expl/background/israel/the-day-of-the-lord.md, expl/background/israel/jesus-and-the-covenant.md, and expl/background/israel/the-second-exodus.md.

What the Day of the Lord actually is. It isn’t simply “the end of the world” — it’s the day that finally delivers what the covenant always promised: judgment on Israel’s enemies, the restoration of Israel, judgment on the wicked within Israel itself, and the fulfillment of remaining promises like the outpouring of the Spirit. When Israel returned from exile, the temple was rebuilt under Ezra and the wall under Nehemiah, with Joshua as high priest and Zerubbabel as ruler — the outward pieces were in place. But the substance wasn’t: the people were still under foreign rule in every meaningful sense (Ezra 9), the promised blessing hadn’t arrived (Haggai 1:7-12), and the outpouring of the Spirit hadn’t happened (Ezekiel 36:25-27). One citation correction worth noting here: the source material’s claim that “the land was still under the curse” points to Malachi 3:10-11 — but those verses are actually the positive promise of blessing if the people bring the full tithe. The explicit statement that the land is under a curse for withholding it comes one verse earlier, in Malachi 3:9. Small fix, same conclusion: by every prophetic measure, the exile hadn’t really ended — it just changed its outward shape.

The disagreement about how the Day of the Lord would arrive. By Jesus’s time, Jewish groups sharply disagreed on the details: Qumran expected withdrawal from society with increased Torah observance; the Pharisees pushed for increased observance within society as it stood; the Sadducees favored cooperation with Rome (worth a small correction here — the Sadducees are better described as holding a comparatively minimal view of legal observance, rejecting the Pharisees’ oral tradition, rather than favoring “increased” observance); and the Zealots wanted increased observance paired with active armed resistance. Into that fractured landscape, Mark opens his gospel with the word euangelion — the term for an imperial accession announcement — immediately following it with a quotation from Isaiah at the exact point the Day of the Lord is announced. The claim is audacious: the true king, and the true fulfillment, has arrived, and He looks nothing like any faction expected.

How Jesus retraced Israel’s own story. The calling of the twelve disciples on a mountain echoes Sinai and the twelve tribes; Jesus’s forty days of temptation in the desert deliberately mirrors — and reverses — Israel’s forty years of failure after the twelve spies; the casting out of demons pictures God’s restorative action against Israel’s true enemies (not Rome, as many expected, but the powers behind Rome); the multiplication of bread recalls the manna in the wilderness; meals with sinners anticipate the final banquet of God with His people. Even the kingdom’s arrival came in a deliberately hidden form Jesus kept returning to — the sower, the mustard seed, the yeast (notably a symbol never used elsewhere in the Old Testament for God’s kingdom, since leaven typically symbolizes corruption) — the smallest, least likely thing becoming the largest, a reversal Israel should already have recognized from its own election as the smallest of nations (Deuteronomy 7:7).

A hard, honest word from the source material worth naming carefully. Some of what Israel expected turned out to be misconceptions: that the enemies were the oppressing Romans (Jesus named the real enemies as the demonic powers, Mark 3:22-27), that the faithful “remnant” meant the visibly religious, and that ruling meant ruling the way other nations ruled. The accuracy review flagged this as an area where the source material generalizes about “what Israel thought” without citing the range of Second Temple sources that would support it — worth treating as a broad, representative pattern rather than a airtight claim about every first-century Jewish person’s belief, especially given how much the same source material shows these groups disagreeing with each other just paragraphs earlier.

Already, but not yet. When Jesus read Isaiah 61:1-2 in the synagogue and declared it fulfilled (Luke 4:16-21), He stopped mid-sentence — before “the day of vengeance of our God.” That’s not an accident. Jesus didn’t come to judge yet, because judging now would mean judging everyone (Matthew 11:20-24). He effectively split the Day of the Lord into two comings: the first bringing grace, the second bringing final judgment. This is the theological backbone of the whole “already/not yet” framework you’ll hear referenced throughout the rest of this series.

The second Exodus, traced through Luke-Acts. Mark and Luke both open with the same Isaiah 40 quotation — “prepare the way of the Lord” — because “the way” is the Exodus itself: God’s means of restoring Israel, running now through the church. Acts returns to this “the way” language six times, and develops it through Pentecost’s inclusion of Jews from every nation, the coming of the Spirit, the restoration of David’s kingdom, and the inclusion of the excluded. One citation correction: the “fig tree” comparison in the Mark/Isaiah table (Jesus’s judgment on the unfruitful fig tree framing His arrival in Jerusalem) is properly grounded in Mark 11:12-14, 20-21, not Revelation 17:14 (which is about the beast and ten kings, unrelated to fig trees or fruitfulness) — a mismatched citation in the source material worth flagging if you go looking at it directly.

Discussion Questions

Understanding the text:

1. Why didn’t the return from Babylonian exile actually feel like the fulfillment of the covenant promises, even though the temple and walls were rebuilt?
2. Trace two or three ways Jesus’s early ministry deliberately retraces and reverses Israel’s Exodus story. What does the reversal (succeeding where Israel failed) tell us about who Jesus is?
3. Why did Jesus stop mid-verse in Luke 4, leaving out “the day of vengeance”? What does that tell us about the “already/not yet” shape of His mission?

So what for us: 4. Several first-century groups disagreed sharply about what faithfulness to God should look like in a compromised political situation. Where do believers today disagree just as sharply — and how does Jesus’s own redefinition of “the real enemy” speak into those disagreements? 5. The kingdom arrived hidden, in small, unimpressive ways (a mustard seed, yeast, a handful of disciples). Where do you expect God to work through visible strength when He might actually be working through something small and easy to overlook? 6. If we live in the “already/not yet” — grace now, judgment still to come — how should that shape both our patience with a broken world and our urgency about the gospel?

Closing Prayer Prompt

Thank Jesus for stopping mid-sentence in Nazareth — for choosing grace over immediate judgment, and for retracing Israel’s whole failed story to succeed where it failed. Ask for eyes to see where God is working small and hidden in your own life and church right now, rather than only recognizing Him in what looks impressive.
