Luke 17:30

Analysis & Commentary

Even thus shall it be in the day when the Son of man is revealed. Jesus applies both historical examples (Noah and Lot) to His second coming. Even thus (κατὰ τὰ αὐτὰ, kata ta auta—"according to these same things") draws direct parallel between past judgments and future eschatological judgment. In the day when the Son of man is revealed (ᾗ ἡμέρᾳ ὁ υἱὸς τοῦ ἀνθρώπου ἀποκαλύπτεται, hē hēmera ho huios tou anthrōpou apokalyptetai)—the verb apokalyptō (ἀποκαλύπτεται, is revealed) means to unveil, uncover, make manifest what was hidden.

Currently, Christ's glory is veiled—He reigns from heaven, invisible to human eyes (Colossians 3:3-4). At His return, the veil lifts; He appears in manifest glory (Colossians 3:4, 1 John 3:2). The parallel with Noah and Lot emphasizes:

1. Normalcy—life continues as usual until the moment of revelation
2. Suddenness—judgment strikes without further warning
3. Totality—no escape for the unprepared
4. Separation—the righteous saved, the wicked destroyed
5. Irreversibility—no second chances after judgment falls.

   The day (ᾗ ἡμέρᾳ, hē hēmera) is singular, definite—not gradual process but specific moment when history culminates in Christ's appearing. 2 Thessalonians 1:7-10 describes this revelation: Christ returns 'in flaming fire taking vengeance' on those who 'know not God,' while simultaneously glorifying Himself in His saints.

That day divides humanity finally and forever—vindication for believers, destruction for unbelievers. The warning: prepare now, while grace extends; judgment comes suddenly, irreversibly.

Historical Context

First-century Jewish apocalyptic expectation anticipated 'the day of the Lord'—God's decisive intervention in history to judge evil and establish His kingdom (Joel 2:1-11, Amos 5:18-20, Zephaniah 1:14-18). Jesus appropriates this language, identifying 'the day of the Lord' with 'the day of the Son of man'—His return in glory. The Pharisees asked 'when the kingdom of God should come' (v. 20); Jesus responds that His second coming will be unmistakable, like lightning (v. 24), like Noah's flood, like Sodom's destruction.

Early Christians lived expecting this day. Paul wrote of 'the day of Christ' (Philippians 1:6, 10, 2:16), 'the day of the Lord' (1 Thessalonians 5:2, 2 Thessalonians 2:2), 'that day' (2 Thessalonians 1:10, 2 Timothy 1:12, 18, 4:8). Peter warned it would come 'as a thief in the night' when 'the heavens shall pass away with a great noise, and the elements shall melt with fervent heat' (2 Peter 3:10). The consistent apostolic message: live holy lives in light of coming judgment (2 Peter 3:11-14). Jesus' teaching here grounds this expectation in historical precedent—as surely as God judged Noah's and Lot's generations, He will judge ours.

Questions for Reflection

• How should the certainty that Christ will be revealed in judgment 'even thus' (exactly like Noah's flood and Sodom's fire) affect daily priorities?
• What does it mean to live ready for 'the day' when Christ is revealed, given that it will come suddenly like past judgments?
• How does the revelation of Christ's glory comfort believers while terrifying unbelievers (2 Thessalonians 1:7-10)?
