What does "in a flash, in the twinkling of an eye" signify?

Setting the Scene

1 Corinthians 15:52: “in an instant, in the twinkling of an eye, at the last trumpet. For the trumpet will sound, the dead will be raised imperishable, and we will be changed.”


The Greek Snapshot

• “Instant” (en atomō) – the smallest indivisible unit of time; shorter than a heartbeat.

• “Twinkling” (rhipē) – the rapid flick of an eyelid or a quick flash of light.

Together they emphasize absolute immediacy.


What Happens in That Split Second

• The last trumpet sounds—God’s final summons (cf. 1 Thessalonians 4:16).

• All who have died in Christ are raised with incorruptible bodies.

• Believers still alive are transformed without dying (1 Corinthians 15:51).

• Mortality is swallowed up by life—our bodies become like Christ’s glorious body (Philippians 3:20-21).


Linked Passages That Echo the Suddenness

Matthew 24:27—Christ’s coming “like lightning.”

Luke 17:34-36—two people side by side, one taken, one left.

1 John 3:2—“We know that when Christ appears, we shall be like Him.”

John 14:2-3—Jesus promises to return and take us to Himself.

2 Corinthians 5:1-5—God prepares us for a heavenly dwelling.


Why Instantaneity Matters

• Affirms God’s sovereign power: He needs no gradual process to glorify His people.

• Offers unshakeable hope: death will have no time to sting, and decay cannot cling.

• Calls for readiness: because the change is sudden, continual faithfulness is vital (Matthew 24:42-44).

• Comforts the grieving: reunion with believing loved ones will be immediate and bodily (1 Thessalonians 4:17-18).


Living in Light of This Truth

• Stand firm, abounding in the Lord’s work, knowing it is not in vain (1 Corinthians 15:58).

• Fix hearts on the incorruptible inheritance kept in heaven (1 Peter 1:3-4).

• Encourage one another with the certainty of rapid, glorious transformation (Hebrews 10:24-25).
