DEEP-DIVE SMALL GROUP DISCUSSION GUIDE

Based on: Investigating Jesus — The Three Ages of Human History Primary Texts: Luke 21:5-28; Matthew 24:1-31 Series: Investigating Jesus (Gospel of Luke) Time: 90-120 minutes

========================================

LEADER PREPARATION

========================================

Overview: This session explores what Jesus called the "Olivet Discourse" — his longest recorded answer to any single question — in which he maps out three distinct ages of human history and calls his followers to faithful readiness. The sermon walked through the end of the age of Judaism, the current age of the Gentiles, and the coming return of Christ. Your group will dig into the historical evidence, the original language, and the theological weight of what Jesus predicted.

Big Idea: Because Jesus' past predictions came true with precise accuracy, his future predictions — including his return — are equally certain, and that certainty should shape how we live right now.

Essential Background:

• The Olivet Discourse gets its name from the Mount of Olives, where Jesus sat when he gave this teaching. It is his longest uninterrupted answer to any question in all four Gospels.
• Herod's Temple was one of the ancient world's greatest architectural achievements — massive limestone blocks, some weighing over 100 tons. When Jesus said "not one stone will be left on another," his disciples would have considered it nearly impossible.
• The historian Josephus (a first-century Jewish eyewitness) and the Roman historian Tacitus both independently recorded the destruction of Jerusalem in 70 AD under the Roman general Titus — precisely as Jesus described it 37 years earlier.
• The Greek word ethnon (nations/Gentiles) is the same root word used in both Luke 21 and Matthew 28:19 (the Great Commission), linking these passages intentionally.

Preparation Checklist:

• Read Luke 21:5-28 and Matthew 24:1-31 twice — slowly
• Review the word studies below so you can share them conversationally
• Think through your own honest answers to the discussion questions
• Pray for each group member by name before they arrive

Facilitator Encouragement: You don't need to be a prophecy expert or a theologian to lead this discussion well. Your job is to ask good questions and create space for honest conversation. The Holy Spirit is the real teacher in the room. Trust the process, trust your group, and trust him.

========================================

OPENING (5-10 minutes)

========================================

Icebreaker Question:

Think about a time someone made a prediction that turned out to be exactly right — maybe a weather forecast, a doctor's prognosis, a coach's pre-game assessment, or something a parent or mentor told you. How did that accurate prediction change how much you trusted that person going forward?

Let a few people share briefly. This question sets up the session's core theme: the credibility of Jesus as a predictor shapes how seriously we take what he says is still coming.

========================================

TEACHING TIME (15-20 minutes)

========================================

Leader note: Share this material conversationally — you're setting the table for discussion, not delivering a lecture. Feel free to paraphrase in your own words.

HISTORICAL & CULTURAL CONTEXT (5-7 minutes)

The Setting: Jesus gave this teaching on the Mount of Olives — his favorite place to pray — just days before his crucifixion. He and his disciples were looking across the Kidron Valley at Herod's Temple, which was still under construction and had been for decades. Imagine standing next to the Empire State Building while it's being built and hearing someone say, "Every single piece of this will be demolished." That's the scale of what Jesus said.

The Temple's Significance: For Jewish people, the Temple wasn't just a religious building — it was the center of their entire identity. It was where heaven and earth intersected. The entire sacrificial system — priests, offerings, the Day of Atonement, the Holy of Holies — all of it happened there. When Jesus predicted its destruction, he was predicting the end of an entire world.

What Actually Happened: In 70 AD, exactly as Jesus predicted, the Roman general Titus besieged Jerusalem. A rogue soldier threw a torch into the Temple, the gold melted into the cracks between the stones, and the soldiers literally pried apart every stone to retrieve the gold. The Temple was completely dismantled — not one stone left on another. The Jewish people were scattered across the nations. Both Josephus and Tacitus recorded it. Five for five: every specific prediction Jesus made came true.

Why This Matters for the Rest: If Jesus was 100% accurate about the past predictions, we have every reason to take seriously what he says about the future ones.

KEY WORD STUDIES (5-7 minutes)

"Nations" / "Gentiles" — Greek: ethnon (ἐθνῶν) This is the word from which we get our English word ethnicity. In Luke 21, Jesus calls the current age "the times of the Gentiles" (ethnon). Remarkably, the identical Greek word appears in Matthew 28:19 — "Go and make disciples of all nations" (ta ethne). Jesus is connecting the Great Commission directly to this age of history. The mission of the church — taking the gospel to every people group — is literally what defines the era we're living in.

"Birth Pains" — Greek: ōdinōn (ὠδίνων) Jesus uses this word to describe the wars, famines, and earthquakes that will increase before his return. The same word appears in Romans 8:22 where Paul writes that "the whole creation has been groaning as in the pains of childbirth." This is crucial: Jesus isn't describing random destruction — he's describing labor. Something is being born. The chaos isn't the end of the story; it's the delivery room for what God is bringing forth.

"Apostasy" / "Turn Away" — Greek: skandalisthēsontai (σκανδαλισθήσονται) In Matthew 24:10, Jesus says "many will turn away from the faith." The root Greek word is skandalon — the same word from which we get "scandal." It literally means a trap or a stumbling block. Jesus is saying that in the end times, many will be tripped up, caught in a snare, and fall away. This isn't casual drift — it's a decisive stumbling. The word carries urgency: stay alert, stay rooted, don't be caught off guard.

IMPORTANT CROSS-REFERENCES (3-5 minutes)

Have your group keep their finger in Luke 21 while you briefly note these connections:

• Hebrews 10:1 — "The law is only a shadow of the good things that are coming." Everything in the Temple system — the priests, the sacrifices, the Day of Atonement — pointed forward to Jesus. He is the reality the shadow was pointing toward.
• Romans 8:19-22 — Creation itself is groaning in eager expectation, like a woman in labor. The chaos of this age is purposeful, not random.
• 2 Peter 3:9 — "The Lord is not slow in keeping his promise... He is patient, not wanting anyone to perish." God's apparent delay is actually mercy extended.
• Galatians 3:28 — "There is neither Jew nor Gentile... for you are all one in Christ Jesus." The age of the Gentiles isn't just about geography — it's about a new humanity being formed in Christ.
• Revelation 20:4 — John's vision of the martyrs connects directly to Jesus' warning about persecution in Matthew 24.

========================================

SCRIPTURE READING & OBSERVATION (10-15 minutes)

========================================

Read aloud: Luke 21:5-19 and Matthew 24:3-14 Suggestion: Have two different people read — one from the NIV, one from the ESV or NLT. Notice any differences in wording.

Observation Questions (These don't require answers yet — just notice and wonder):

1. What specific words or phrases does Jesus repeat across both passages?
2. What surprises you — either about what Jesus says or how he says it?
3. What emotions do you notice in Jesus' words? Is he alarmed? Calm? Urgent?
4. What questions does this passage raise for you that you'd like to dig into?

========================================

DEEP DIVE DISCUSSION (40-50 minutes)

========================================

SECTION A: UNDERSTANDING THE TEXT (3-4 questions)

1. The sermon described the Temple as the intersection point between heaven and earth — the place where sinful people could approach a holy God through priests and sacrifices. When Jesus predicted the Temple's destruction, what was he actually announcing about the old system? And what does Hebrews 10:1 add to that picture?

2. Jesus made five specific predictions in 33 AD about events that happened in 70 AD. Walk through them together. Why do you think Jesus was so specific — naming details like pregnant women, fleeing to the mountains, and not one stone remaining? What does that level of specificity tell us about how Jesus viewed the future?

[Leader Tip: If the group gets stuck, ask this follow-up: "What's the difference between a vague prediction and a specific one? Why would specificity matter when we're deciding whether to trust a prophet?" This helps connect historical accuracy to present-day trust.]

3. Jesus uses the phrase "birth pains" to describe the wars, famines, and chaos that will increase before his return. How does that metaphor change the way you read the signs he lists? What's the difference between "the world falling apart" and "the world in labor"?

4. In the word study, we saw that the Greek word ethnon connects Luke 21 (the times of the Gentiles) directly to Matthew 28 (the Great Commission). What does it mean that the defining mission of the church — making disciples of all nations — is literally what names the age we're living in?

[Leader Tip: This is a rich question. If discussion is shallow, try: "If the age we're in is literally called 'the time of the nations,' what does that say about the church's purpose during this age? What happens if the church stops pursuing that mission?"]

SECTION B: THEOLOGICAL CONNECTIONS (2-3 questions)

5. The sermon drew a detailed line from the Temple system (priests, sacrifices, the Day of Atonement, the scapegoat) to Jesus himself — showing how everything in the old system pointed forward to him. Which of those connections hit you hardest, and why? What does it reveal about how God has been telling one consistent story across thousands of years?

6. 2 Peter 3:9 says God is "patient, not wanting anyone to perish." The sermon pointed out that every day Jesus waits, thousands more people come to faith — including 16,000+ per day on the African continent alone. How does this reframe the question "Why is Jesus taking so long?" What does it reveal about the character of God?

[Leader Tip: Watch for two extremes here — people who find this deeply comforting and people who find it frustrating ("but what about all the suffering in the meantime?"). Both responses are valid and worth exploring. Don't rush past the tension.]

7. Jesus warns in Matthew 24 that false prophets will perform "great signs and wonders" — miracles — but will not be from God. What criteria does Jesus give for evaluating spiritual leaders and movements? How does this connect to what the sermon said about reading Scripture for yourself rather than outsourcing your spiritual discernment entirely to others?

SECTION C: CONTEMPORARY APPLICATION (3-4 questions)

8. The sermon made the point that the church in America has largely been protected from the kind of persecution Jesus describes — but that more Christians have been martyred in the last century than in all previous centuries combined. How does that reality land with you? Does it change how you think about your faith, your comfort, or your brothers and sisters around the world?

9. Jesus' first sign of the end is a rise in global deception — people using Scripture to lead others away from Christ. The sermon gave a pointed warning: "Just because someone has a verse doesn't mean they're right. Satan knows the Bible better than you do." What habits or practices protect a person from being deceived? What makes someone spiritually vulnerable to deception?

[Leader Tip: This can become abstract quickly. Ground it with a follow-up: "What does it actually look like in your daily life to 'measure everything against the word of God'? What would have to change for that to be real for you?"]

10. The sermon described the church's mission — planting churches, reaching unreached people, giving millions to global missions — as a direct response to the theological reality that we are in the age of the Gentiles. How does understanding why the church does what it does change how you participate in it? Does knowing the theological stakes make generosity, serving, or sharing your faith feel different?

11. Jesus closes the Olivet Discourse with a simple command: "You must be ready." Not "you should be informed" or "you should be interested" — but ready. What does readiness actually look like for a follower of Jesus in 2025? What's the difference between being fascinated by end-times information and actually being prepared?

[Leader Tip: Don't let this stay abstract. Push gently toward the personal: "If someone asked you tomorrow, 'Are you ready?' — what would your honest answer be? What would make you feel more ready?"]

========================================

PERSONAL APPLICATION (15-20 minutes)

========================================

Give the group 2-3 minutes of quiet reflection before discussing. Encourage them to write something down.

Reflective Questions:

1. The sermon opened with the image of a countdown clock — always visible, always ticking. If you genuinely believed the hour was late, what would you do differently this week? This month?

2. Which of the four signs Jesus described — deception, global chaos, persecution, apostasy — do you feel least prepared for? What would it look like to take that seriously?

3. The sermon connected the age of the Gentiles to the Great Commission, and described the church's global mission as the defining work of this era. Where does your life intersect with that mission? Where could it?

This Week Challenge:

Choose one of the following — pick the one that stretches you most:

• Read: Spend 15 minutes in Matthew 24 or Luke 21 on your own. Write down one thing that surprises you and one thing that challenges you.
• Pray: Pray specifically for one person in your life who doesn't know Jesus yet — by name, every day this week. Consider what it would look like to take a step toward them.
• Act: If you haven't been through a discipleship experience like Rooted, take a concrete step toward deeper formation in community. Spiritual readiness isn't built alone.

========================================

PRAYER & CLOSING (10 minutes)

========================================

Suggested Prayer Focus:

Close by praying in three movements — invite different group members to pray for each:

1. Gratitude — Thank God that Jesus' past predictions came true, and that his faithfulness is the foundation for trusting his future promises.

2. Intercession — Pray by name for people in your lives who don't yet know Jesus. Pray for the global church — especially believers in places where following Christ carries real cost.

3. Readiness — Ask God to make your group people who are genuinely prepared — not just informed — for what is coming. Ask for courage, rootedness, and faithfulness.

Option: Break into pairs for the final prayer time. This allows more personal, honest prayer and builds connection within the group.

Closing Word for the Leader:

End with this reminder: The point of studying the end times isn't anxiety — it's faithfulness. Jesus didn't give us these signs to make us afraid. He gave them to us so we wouldn't be surprised, wouldn't be deceived, and wouldn't waste the time we have. The hour is late. That's good news — because it means the best is still coming.

For further study: Hebrews 9-10 (the Temple as shadow pointing to Christ), Romans 8:18-25 (creation groaning), 2 Thessalonians 2 (the man of lawlessness), Revelation 6-7 (the seals and the great multitude)
