Study 8: Does "Forever" Mean Eternal? (New Testament)

The Greek Word Aionios and the Duration of Punishment

A Note on How to Study

Throughout this series, we distinguish between what the Bible explicitly says and what people infer from the Bible. These are not the same thing.

  • Explicit: You can point to a verse and quote it. The text directly says this.
  • Inference: Someone claims the Bible teaches something, but no single verse says it. They have drawn a conclusion — possibly a good one, possibly not — but the conclusion itself is not in the text.

In Study 7 we examined the Hebrew word olam and found that its duration is determined by the subject it describes, not by the word itself. This study asks the same question about the Greek New Testament equivalent: does aionios inherently mean "eternal/endless," or does it function the same way olam does?

Section A: What Does Aionios Mean?

  1. The Greek word aionios (G166) is derived from aion (G165), a noun meaning "an age." Strong's defines aionios as "perpetual (also used of past time, or past and future as well)." Based on this definition, does aionios describe a fixed duration, or does it mean "pertaining to an age" with the actual duration determined by context?

  2. Read Romans 16:25. Paul writes of the mystery "kept secret since the world began" — literally "in aionios times" (chronois aioniois). Here aionios refers to past time. If aionios meant "strictly endless future," could it describe the past?

  3. Read 2 Timothy 1:9. God's grace was given "before the world began" — literally "before aionios times" (pro chronon aionion). If aionios meant "eternal," what would "before eternity" mean? Does the phrase make sense?

  4. Read Titus 1:2. In this single verse, Paul uses aionios for both "eternal life" (zoe aionios, looking forward) and "before the world began" (pro chronon aionion, looking backward). If the same word can point both forward and backward in the same sentence, what does this tell you about whether aionios means "endless future"?

Section B: Two Greek Words — Aionios vs. Aidios

  1. Greek has a separate word, aidios (G126), derived from aei (G104, "always"). Strong's defines aidios as "everduring (forward and backward, or forward only)." Aidios occurs only twice in the NT. If Greek already had a word that specifically meant "everduring," what does it suggest that the NT predominantly uses aionios (from aion, "age") instead?

  2. Read Romans 1:20. Paul describes God's "eternal power" using aidios — not aionios. Why might Paul choose the "everduring" word (aidios) for God's nature rather than the "age-pertaining" word (aionios)?

  3. Read Jude 1:6-7. In verse 6, Jude uses aidios for the "everlasting chains" holding fallen angels. In the very next verse (v.7), he uses aionios for the "eternal fire" that destroyed Sodom. The same author, in adjacent verses, uses two different words. If aidios and aionios meant the same thing, why would Jude switch words?

  4. Sodom's "eternal fire" (Jude 1:7) destroyed the city. Is Sodom still burning today? What does this tell you about the kind of "eternal" that aionios describes here?

Section C: Aionios in Key Passages

  1. Read Matthew 25:46. "These shall go away into everlasting punishment (kolasin aionion): but the righteous into life eternal (zoen aionion)." The same adjective (aionios) modifies both "punishment" and "life." Some argue this means both must have identical duration. Now recall Titus 1:2, where the same word (aionios) points both forward and backward in the same verse. Does a single adjective necessarily carry the same duration for every noun it modifies?

  2. Read 2 Thessalonians 1:9. The wicked "shall be punished with everlasting destruction (olethros aionios)." The word translated "destruction" (olethros, G3639) means "ruin" or "death." No Greek lexicon defines olethros as "torment" or "ongoing suffering." What does this verse describe — eternal torment, or eternal destruction?

  3. Read Hebrews 9:12. Christ obtained "eternal redemption" (aionios lytrosis) "once" (hapax). Does "eternal redemption" mean the act of redeeming goes on forever, or that the result of the redemption is permanent?

  4. Now consider "eternal judgment" (Heb 6:2), "eternal salvation" (Heb 5:9), and "eternal inheritance" (Heb 9:15). In each case, the event is completed and the result is permanent. What does this pattern tell you about how aionios functions — does it describe an ongoing process, or a permanent result?

Section D: "For Ever and Ever" in Revelation

  1. The phrase "for ever and ever" (eis tous aionas ton aionon, literally "unto the ages of the ages") is used approximately 19 times for God and Christ in doxological passages. It is used in judgment contexts only 3 times — all in Revelation (14:11; 19:3; 20:10). What does this distribution suggest about whether these three judgment passages should be read as literal didactic teaching or as apocalyptic imagery?

  2. Read Revelation 14:11. "The smoke of their torment ascendeth up for ever and ever." Now read Isaiah 34:10, where the smoke of Edom's judgment "shall go up for ever." Is Edom still burning? If the OT "smoke ascending forever" described a completed judgment, what does the same language in Revelation describe?

  3. Read Revelation 20:9-10. In verse 9, fire comes down from heaven and "devoured" (katesthion — consumed/destroyed) the human enemies. In verse 10, the devil, the beast, and the false prophet are "tormented day and night for ever and ever." Note that the beast and false prophet are symbolic entities (Rev 19:20). Are the human enemies given the same fate as the devil and the symbolic entities, or a different fate?

Explicit or Inference?

For each statement below, decide: Does the Bible explicitly say this (you can point to a verse), or is it an inference (a conclusion someone draws that no verse directly states)?

A. "Aionios is used for past time in Romans 16:25, 2 Timothy 1:9, and Titus 1:2 — proving it does not inherently mean 'endless future.'" - [ ] Explicit — the Bible says this - [ ] Inference — someone concluded this

B. "Aionios always means 'eternal/endless' regardless of context." - [ ] Explicit — the Bible says this - [ ] Inference — someone concluded this

C. "Jude uses aidios (G126) for the angels' chains and aionios (G166) for Sodom's fire in adjacent verses." - [ ] Explicit — the Bible says this - [ ] Inference — someone concluded this

D. "Because the same adjective (aionios) modifies both 'punishment' and 'life' in Matthew 25:46, both must last exactly the same duration." - [ ] Explicit — the Bible says this - [ ] Inference — someone concluded this

E. "The 'smoke ascending for ever and ever' in Revelation 14:11 teaches that all the wicked will experience literal endless conscious torment." - [ ] Explicit — the Bible says this - [ ] Inference — someone concluded this
