Omega

Omega is the last letter of the Greek alphabet, used in the New Testament exclusively in the title Alpha and Omega — a divine self-designation meaning the first and the last or the beginning and the end. The title appears three times in Revelation: attributed to the LORD God in 1:8 (I am the Alpha and the Omega, the beginning and the ending, says the Lord God who is and who was and who is to come, the Almighty); to the risen Christ in 22:13 (I am the Alpha and the Omega, the first and the last, the beginning and the end); and in 21:6 where God declares the same.

The title echoes the Hebrew prophetic formula in Isaiah 41:4; 44:6; and 48:12, where God identifies himself as the first and the last. By claiming this title in Revelation, Christ is identified with the eternal God of Israel — the one who encompasses all of history and whose sovereign purpose spans from creation to new creation.
