What does Jesus mean when He says I am Alpha and Omega?
The phrase Alpha and Omega means Christ is the first and last letters of the Greek alphabet—the beginning and the end, the first and the last. It declares His eternity: He existed from eternity past, will exist to eternity future, and did not begin at Bethlehem.
Les teaches that Alpha and Omega are the first and last letters of the Greek alphabet, so Jesus is saying He is A and Z, the beginning and the end, the first and the last. Les emphasizes that Christ was eternal, from eternity past to eternity future, and he corrects the idea that Christ came on the scene only at Bethlehem when born of Mary. Les points out that Christ, God the Son, called everything into being in Genesis 1, was manifested throughout the Old Testament, and in the New Testament the invisible person of the Godhead became flesh, visible and tangible—yet He has always been.
I am Alpha and Omega, the beginning and the end, the first and the last.
