Ω, ω
Omega
Noun (letter) / Title
Omega / Last Letter

Definition

The Greek letter omega (Ω, ω) is the last letter of the Greek alphabet, corresponding in theological significance to the Hebrew tav (&tav;). As Strong’s G5598, it represents finality, completion, and consummation. In the Book of Revelation, Jesus applies it to Himself in the title “I am the Alpha and the Omega” (Revelation 1:8; 21:6; 22:13) — pairing it with alpha (G1) to declare that He is the beginning and the end, the first and the last. Omega signifies that Christ is the goal, telos, and consummation of all things — history is not random but moves toward Him.

Usage & Theological Significance

If alpha declares that Christ is the origin of all things, omega declares that He is the destination. The divine title “Alpha and Omega” encompasses the full sweep of redemptive history: God initiated creation (alpha) and will consummate it in the new heaven and new earth (omega). Nothing falls outside this span. The title appears three times in Revelation — in 1:8 spoken by “the Lord God, the Almighty,” in 21:6 by the One on the throne making all things new, and in 22:13 by Jesus Himself alongside “the First and the Last, the Beginning and the End.” This threefold repetition in the final book of the Bible functions as a capstone over all of Scripture: the God who spoke “Let there be light” in Genesis 1:3 is the same God who declares “It is done” in Revelation 21:6. Omega is not merely an ending — it is the fulfillment of every divine purpose, the point at which every promise finds its “Yes” and “Amen” (2 Corinthians 1:20).
