Alpha and Omega

Alpha and Omega are the first and last letters in the Greek alphabet.  They stand for the beginning and the end, the first and the last.  They are used as a mongram of Christ indicating that he is eternal rather than limited in time or place.  This is taken from Rev 1:8, 17; 21:6 and 22:13 where Christ is identified as the Alpha and the Omega, the First and the Last, the Beginning and the End.  This image is also seen in Isaiah where God says, “I am the first and I am the last; apart from me there is no God, (Is 44:6). 

The image in Revelation closely identifies Jesus with God, the Creator and Sustainer of all that is.  Those who worship him with John the author of Revelation are told, “Do not be afraid.  I am the First and the Last.  I am the Living One; I was dead, and behold I am alive for ever and ever!  And I hold the keys of death and Hades” (Rev 1:17-18).
