ALPHA (ăl'fa). First letter of the Greek alphabet (A). The word “alphabet,” indicating a list of elementary sounds in any language, comes from the first two Greek letters, alpha and beta. In contrast is omega, the last letter of the Greek alphabet. Combined with alpha it signifies completeness, as “from A to Z” in modern usage. So God is the Alpha and the Omega, the First and the Last, the Beginning and the End (Rev.1.8), as is also Christ (Rev.21.6; Rev.22.13). Compare Isa.41.4; Isa.44.6.
