HELPS Word-studies

Cognate: 166 aiṓnios (an adjective, derived from 165 /aiṓn ("an age, having a particular character and quality") – properly, "age-like" ("like-an-age"), i.e. an "age-characteristic" (the quality describing a particular age); (figuratively) the unique quality (reality) of God's life at work in the believer, i.e. as the Lord manifests His self-existent life (as it is in His sinless abode of heaven). "Eternal (166 /aiṓnios) life operates simultaneously outside of time, inside of time, and beyond time – i.e. what gives time its everlasting meaning for the believer through faith, yet is also time-independent. See 165 (aiōn).

[166 (aiṓnios) does not focus on the future per se, but rather on the quality of the age (165 /aiṓn) it relates to. Thus believers live in "eternal (166 /aiṓnios) life" right now, experiencing this quality of God's life now as a present possession. (Note the Gk present tense of having eternal life in Jn 3:36, 5:24, 6:47; cf. Ro 6:23.)]

STRONGS NT 166: αἰώνιος

αἰώνιος, , and (in 2 Thessalonians 2:16; Hebrews 9:12; Numbers 25:13; Plato, Tim., p. 38 b. (see below); Diodorus 1:1; (cf. WHs Appendix, p. 157; Winers Grammar, 69 (67); Buttmann, 26 (23))) αἰώνιος, αἰώνια, αἰώνιον (αἰών);

1. without beginning or end, that which always has been and always will be: Θεός, Romans 16:26 ( μόνος αἰώνιος, 2 Macc. 1:25); πνεῦμα, Hebrews 9:14.

2. without beginning: χρόνοις αἰωνίοις, Romans 16:25; πρό χρόνων αἰωνίων, 2 Timothy 1:9; Titus 1:2; εὐαγγέλιον, a gospel whose subject-matter is eternal, i. e., the saving purpose of God adopted from eternity, Revelation 14:6.

3. without end, never to cease, everlasting: 2 Corinthians 4:18 (opposed to πρόσκαιρος); αἰώνιον αὐτόν, joined to thee forever as a sharer of the same eternal life, Philcmon 1:15; βάρος δόξης, 2 Corinthians 4:17; βασιλεία, 2 Peter 1:11; δόξα, 2 Timothy 2:10; 1 Peter 5:10; ζωή (see ζωή, 2 b.); κληρονομία, Hebrews 9:15; λύτρωσις, Hebrews 9:12; παράκλησις, 2 Thessalonians 2:16; σκηναί, abodes to be occupied forever, Luke 16:9 (the habitations of the blessed in heaven are referred to, cf. John 14:2 (also,dabo eis tabernacula aeterna, quae praeparaveram illis, 4 Esdras (Fritzsche, 5 Esdr.) []); similarly Hades is called αἰώνιος τόπος, Tobit 3:6, cf. Ecclesiastes 12:5); σωτηρία, Hebrews 5:9; (so Mark 16 (WH) in the (rejected) 'Shorter Conclusion'). Opposite ideas are: κόλασις, Matthew 25:46; κρίμα, Hebrews 6:2; κρίσις, Mark 3:29 (Rec. (but L T WH Tr text ἁμαρτήματος; in Acta Thom. § 47, p. 227 Tdf., ἔσται σοι τοῦτο εἰς ἄφεσιν ἁμαρτιῶν καί λύτρον αἰωνίων παραπτωμάτων, it has been plausibly conjectured we should read λύτρον, αἰώνιον (cf. Hebrews 9:12))); ὄλεθρος (Lachmann text ὀλέθριος, 2 Thessalonians 1:9 (4 Macc. 10:15); πῦρ, Matthew 25:41 (4 Macc. 12:12 αἰωνίῳ πυρί καί βασάνοις, αἱ εἰς ὅλον τόν αἰῶνα οὐκ ἀρνήσουσί σε). (Of the examples of αἰώνιος from Philo (with whom it is less common than ἀΐδιος, which see, of which there are some fifty instances) the following are noteworthy: de mut. nora. § 2; de caritate § 17; κόλασις αἰώνιος fragment in Mang. 2:667 at the end (Richter 6:229 middle); cf. de praem, et poen. § 12. Other examples are de alleg, leg. iii., § 70; de poster. Caini § 35; quod deus immut. § 30; quis rer. div. her. § 58; de congressu quaer, erud. § 19; de secular sec 38; de somn. ii. § 43; de Josepho § 24; quod omn. prob. book § 4, § 18; de ebrietate § 32; de Abrah. § 10; ζωή αἰώνιος: de secular § 15; Θεός () αἰώνιος: de plantat. § 2, § 18 (twice), § 20 (twice);de mundo § 2. from Josephus: Antiquities 7, 14, 5; 12, 7, 3; 15, 10, 5; b. j. 1, 33, 2; 6, 2, I; κλέος αἰών Antiquities 4, 6, 5; b. j. 3, 8, 5, μνήμη αἱ.: Antiquities 1, 13, 4; 6, 14, 4; 10, 11, 7; 15, 11, 1; οἶκον μέν αἰώνιον ἔχεις (of God), Antiquities 8, 4, 2; ἐφυλάχθη Ἰωάννης δεσμοῖς αἰωνίοις, b. j. 6, 9, 4. SYNONYMS: ἀΐδιος, αἰώνιος: ἀΐδιος covers the complete philosophic idea — without beginning and without end; also either without beginning or without end; as respects the past, it is applied to what has existed time out of mind. αἰώνιος (from Plato on) gives prominence to the immeasurableness of eternity (while such words as συνεχής continuous, unintermitted, διατελής perpetual, lasting to the end, are not so applicable to an abstract term, like αἰών); αἰώνιος accordingly is especially adapted to supersensuous things, see the N. T. Cf. Tim. Locr. 96 c. Θεόν δέ τόν μέν αἰώνιον νόος ὄρη μόνος etc.; Plato, Tim. 37 d. (and Stallbaum at the passage); 38 b. c.; legg. x., p. 904 a. ἀνώλεθρον δέ ὄν γενόμενον, ἀλλ' οὐκ αἰώνιον. Cf. also Plato's διαιώνιος (Tim. 38 b.; 39 e.). Schmidt, chapter 45.
