What does Revelation 1:8 Mean?

Verse Meaning

God confirmed the preceding forecast with a solemn affirmation of His eternity and omnipotence. Alpha and omega are the first and last letters of the Greek alphabet and signify here God"s comprehensive control over all things including time. This is probably a merism, a figure of speech in which two extremes represent the whole. John strengthened this point further with present, past, and future references (cf. Revelation 4:8; Revelation 11:17; Hebrews 13:8). He is the originator and terminator of all things. God is not only Lord of the future. He is also powerful enough to bring what John just predicted to pass. He is the "Almighty."
"A weighing of evidence, especially in light of the OT "flavor" of the expression and a recollection that the Father in the OT refers to Himself as "I am" (i.e, the Tetragrammaton, Exodus 3:14; cf. Isaiah 48:12), tips the balance ever so slightly to the side of concluding that God the Father speaks in Revelation 1:8....
"God"s declaration in Revelation 1:8 thus ends with a note of authority. The omnipotent one will surely implement what His prophet has predicted by way of future judgment." [1]
John frequently used "Almighty" as a key name for God in Revelation ( Revelation 1:8; Revelation 4:8; Revelation 11:17; Revelation 15:3; Revelation 16:7; Revelation 16:14; Revelation 19:6; Revelation 19:15; Revelation 21:22).
This whole introduction points to the main event of the following Revelation , the return of Jesus Christ at His second coming ( Revelation 19:11-16). It also presents the triune God as Lord of time (past, present, and future), faithful to His promises, and powerful enough to bring these events to pass. In Genesis , Moses also emphasized God"s power and faithfulness more than any other of His attributes. The last Bible book stresses these qualities of God as does the first Bible book.

Context Summary

Revelation 1:1-8 - The Revelation Of Jesus Christ
In His capacity as mediator, our Lord receives from the Father and transmits to His servants, that they may in turn transmit to the world of men, the great panorama of the future, known to Him from before the foundation of the world. Let us not miss the special benediction which is attached to the patient reading and consideration of this wonderful book.
The seven churches represent the one Church under different phases and possibly in successive stages of its history; the letters addressed to them are therefore universally applicable. Notice the august reference to the Holy Trinity-the eternal Father, the sevenfold Spirit, and our Lord. Our Lord bore a faithful witness even to death; that death was a birth into the risen life, as ours may be; all kings are His vassals.
How wonderful it is to be told in the next verse that He loves us, and has not only washed, but loosed us, as though He had broken the terrible entail. "He breaks the power of canceled sin." Jesus often comes with clouds. We cannot understand His dealings with us, yet those clouds are gold with His light. So He shall come at last. As Alpha He begins, but He never begins without carrying into full effect His purpose as our Omega. [source]

Greek Commentary for Revelation 1:8

The Alpha and the Omega [το Αλπα και το Ο]
The first and the last letters of the Greek alphabet, each with its own neuter (grammatical gender) article. This description of the eternity of God recurs in Revelation 21:6 with the added explanation η αρχη και το τελος — hē archē kai to telos (the Beginning and the End) and of Christ in Revelation 22:13 with the still further explanation ο πρωτος και ο εσχατος — ho prōtos kai ho eschatos (the First and the Last). This last phrase appears also in Revelation 1:17; Revelation 2:8 without το Αλπα και το Ο — to Alpha kai to O The change of speaker here is unannounced, as in Revelation 16:15; Revelation 18:20. Only here and Revelation 21:5. is God introduced as the speaker. The eternity of God guarantees the prophecy just made. [source]
The Lord God [Κυριος ο τεος]
“The Lord the God.” Common phrase in Ezekiel (Ezekiel 6:3, Ezekiel 6:11; Ezekiel 7:2, etc.) and in this book (Revelation 4:8; Revelation 11:17; Revelation 15:3; Revelation 16:7; Revelation 19:6; Revelation 21:22). See Revelation 1:4; Revelation 4:8 for the triple use of ο — ho etc. to express the eternity of God.The Almighty (ο παντοκρατωρ — ho pantokratōr). Late compound (πας — pās and κρατεω — krateō), in Cretan inscription and a legal papyrus, common in lxx and Christian papyri, in N.T. only in 2 Corinthians 6:18 and Revelation 1:8; Revelation 4:8; Revelation 11:17; Revelation 15:3; Revelation 16:7, Revelation 16:14; Revelation 19:6, Revelation 19:15; Revelation 21:22.

[source]
Alpha and Omega [τὸ Α καὶ τὸ Ω]
Rev., rightly, gives the article, “the Alpha,” etc. The words are explained by the gloss, properly omitted from the text, the beginning and the ending. The Rabbinical writers used the phrase from Aleph to Tav, to signify completely, from beginning to end. Thus one says, “Adam transgressed the whole law from Aleph even to Tav.” Compare Isaiah 41:4; Isaiah 43:10; Isaiah 44:6. [source]
The Lord [ὁ Κύριος]
See on Matthew 21:3. The best texts read Κύριος ὁ Θεὸς theLord the God. Rev., the Lord God. [source]
Which is, etc. []
See on Revelation 1:4. “God, as the old tradition declares, holding in His hand the beginning, middle, and end of all that is” (Plato, “Laws,” 715). [source]
The Almighty [ὁ παντοκράτωρ]
Used only once outside of Revelation, in 2 Corinthians 6:18, where it is a quotation. Constantly in the Septuagint. [source]

Matthew 21:3 The Lord [ὁ κύριος]
From κῦρος , supreme power, authority. Hence κύριος , one having authority, lord, owner, ruler. In classical Greek, used of the gods, and in inscriptions applied to different gods, as Hermes, Zeus, etc.; also of the head of the family, who is lord ( κύριος ) of the wife and children (1 Timothy 6:1, 1 Timothy 6:2; Titus 2:9; 1 Peter 2:18), and κύριος (Ephesians 6:9; Colossians 4:1). In the Septuagint it is used by Sarah of her husband (Genesis 3:6). Joseph is called lord of the country (Genesis 18:27; Exodus 4:10). In the New Testament it is a name for God (Matthew 1:20, Matthew 1:22, Matthew 1:24; Matthew 2:15; Acts 11:16; Acts 12:11, Acts 12:17; Revelation 1:8). As applied to Christ, it does not express his divine nature and power. These are indicated by some accompanying word or phrase, as my God (John 20:28); of all (Acts 10:36); to the glory of God the Father (Philemon 2:11); of glory (1 Corinthians 2:8); so that, as a title of Christ, Lord is used in the sense of Master or Ruler, or in address, Sir (Matthew 22:43, Matthew 22:45; Luke 2:11; Luke 6:46; John 13:13, John 13:14; 1 Corinthians 8:6). Ὁ κύριος , the Lord, is used of Christ by Matthew only once (Matthew 21:3) until after the resurrection (Matthew 28:6). In the other gospels and in the Acts it occurs far oftener. Nevertheless, in the progress of Christian thought in the New Testament, the meaning develops toward a specific designation of the divine Saviour, as may be seen in the phrases Jesus, Christ our Lord, Our Lord Jesus Christ, Our Lord, Jesus our Lord. -DIVIDER-

Revelation 1:4 From him which is [απο ο ων]
This use of the articular nominative participle of ειμι — eimi after απο — apo instead of the ablative is not due to ignorance or a mere slip Here again there is a deliberate change from the articular participle to the relative use of ο — ho (used in place of ος — hos to preserve identity of form in the three instances like Ionic relative and since no aorist participle of ειμι — eimi existed). The oracle in Pausanias X. 12 has it: ευς ην ευς εστι ευς εσσεται — Zeus ēnο ερχομενος — Zeus estiο εσομενος — Zeus essetai (Zeus was, Zeus is, Zeus will be).Which is to come “The Coming One,” futuristic use of the present participle instead of απο των επτα πνευματων — ho esomenos See the same idiom in Revelation 1:8; Revelation 4:8 and (without των — ho erchomenos) in Revelation 11:17; Revelation 16:5.From the seven spirits (α — apo tōn hepta pneumatōn). A difficult symbolic representation of the Holy Spirit here on a par with God and Christ, a conclusion borne out by the symbolic use of the seven spirits in Revelation 3:1; Revelation 4:5; Revelation 5:6 (from Zechariah 4:2-10). There is the one Holy Spirit with seven manifestations here to the seven churches (Swete, The Holy Spirit in the N.T., p. 374), unity in diversity (1 Corinthians 12:4).Which are As in Revelation 4:5. [source]
Revelation 1:4 Which is to come [ο ερχομενος]

[source]
Revelation 11:17 O Lord God [Κυριε ο τεος]
Vocative form κυριε — kurie and nominative form ο τεος — ho theos (vocative in use). See Revelation 1:8; Revelation 4:8 for this combination with ο παντοκρατωρ — ho pantokratōr (the Almighty). For ο ων και ο ην — ho ōn kai ho ēn (which art and which wast) see Revelation 1:4, Revelation 1:8; Revelation 4:8; Revelation 16:5. [source]
Revelation 16:5 Which art and which wast [ο ων και ο ην]
See this peculiar idiom for God‘s eternity with ο — ho as relative before ην — ēn in Revelation 1:4, Revelation 1:8; Revelation 4:8, but without ο ερχομενος — ho erchomenos (the coming on, the one who is to be) there for the future as in Revelation 11:17.Thou Holy One (ο οσιος — ho hosios).

Revelation 17:8 And is about to come up out of the abyss [και μελλει αναβαινειν εκ της αβυσσου]
That is, he is going to come to life again.And to go into perdition (και εις απωλειαν υπαγει — kai eis apōleian hupagei). So (and he goes into perdition) the best MSS. read rather than the infinitive υπαγειν — hupagein Most interpreters see here an allusion to the “Nero redivivus ” expectancy realized in Domitian, who was ruling when John wrote and who was called Nero redivivus.Shall wonder First future passive (deponent) of ταυμαζω — thaumazō with which compare εταυμαστη — ethaumasthē in Revelation 13:3.

Revelation 19:6 Saying [λεγοντων]
The best attested reading, genitive plural of λεγω — legō agreeing with οχλου — ochlou (genitive singular), for roll of the waters and the roar of the thunders were not articulate. Some MSS. have λεγοντες — legontes (nominative plural) referring also to οχλου — ochlou though nominative instead of genitive. The fourth “Hallelujah” comes from this vast multitude.The Lord our God, the Almighty (Κυριοσ ο τεοσ ο παντοκρατωρ — Kuriosεβασιλευσεν — ho theosβασιλευω — ho pantokratōr). For this designation of God see also Revelation 1:8; Revelation 4:8; Revelation 11:17; Revelation 15:3; Revelation 16:7, Revelation 16:14; Revelation 19:15; Revelation 21:22.

Revelation 21:5 Behold, I make all things new [Ιδου καινα ποιω παντα]
The first time since Revelation 1:8 that God has been represented as speaking directly, though voices have come out of the throne before (Revelation 21:3) and out of the sanctuary (Revelation 16:1, Revelation 16:17), which may be from God himself, though more likely from one of the angels of the Presence. This message is not addressed to John (Revelation 7:14; Revelation 17:7; Revelation 21:6; Revelation 22:6), but to the entire world of the blessed. See Isaiah 43:18. for the words The idea of a new heaven and a new earth is in Isaiah 65:17; Isaiah 66:22; Psalm 102:25. For the locative here with επι — epi See Revelation 20:11 for the picture. [source]
Revelation 21:6 They are come to pass [Γεγοναν]
Second perfect active indicative of γινομαι — ginomai with αν — ̇an for ασι — ̇asi See Revelation 16:17 for a like use of γεγονεν — gegonen “They have come to pass.” Here again it is the voice of God because, as in Revelation 1:8, He says: [source]
Revelation 21:22 For the Lord God the Almighty, and the Lamb are the temple thereof [ο γαρ Κυριος ο τεος ο παντοκρατωρ ναος αυτης εστιν και το αρνιον]
“For the Lord God, the Almighty, is the sanctuary of it and the Lamb.” The Eternal Presence is the Shekinah Glory of God (Revelation 21:3). In 2 Corinthians 6:16 we are the sanctuary of God here, but now God is our Sanctuary, and so is the Lamb as in chapters Revelation 4:1-11; Revelation 5:1-14. See Revelation 1:8 and often for the description of God here. [source]

Revelation 22:13 I am the Alpha and the Omega [Εγω το Αλπα και το Ο]
Applied to God in Revelation 1:8; Revelation 21:6, and here alone to Christ, crowning proof in this book of Christ‘s deity. So in Revelation 21:6 God is termed, as Christ is here, η αρχη και το τελος — hē archē kai to telos (the beginning and the end), while ο πρωτος και ο εσχατος — ho prōtos kai ho eschatos (the first and the last) is applied only to Christ (Revelation 1:17; Revelation 2:8). Solemn assurance is thus given that Christ is qualified to be the Judge of Revelation 22:12 (cf. Matt 25:31-46). In Hebrews 12:2 Jesus is the αρχηγος και τελειωτης της πιστεως — archēgos kai teleiōtēs tēs pisteōs (the author and finisher of faith). Christ was the Creator of the universe for the Father. So now he is the Consummation of redemption. [source]
