The phrase Alpha and Omega aren’t used for First and Last
because the Old Testament was originally written in Hebrew,
and alpha and omega are Greek letters. The New Testament
was written in Greek and we need to look there to find that
The Last Is The Omega
Alpha and omega are the first and last letters of the Greek
alphabet; thus the meaning of the many scriptural references to
the first and the last. The book of Revelation states:
Alpha and Omega, the first and the last…”
(Rev 1:11, KJV).
(See also Rev. 1:17, 2:8, 22:13.) The One who is the Alpha is
also the Omega—He is both the Creator and the Consumma-
tor. What could make more sense than for the One who creat-
ed the world to be the One who also consummates it?
Thus, the Last is the Omega.
The Omega Is God Almighty
From the book of Revelation we find,
“I am the Alpha and
the Omega, says the Lord God, who is, and who was, and who
is to come, the Almighty”
(Rev. 1:8). (See also Rev. 4:8.)
One sees here that the Lord God Almighty is the Omega.
